# Vx.x.x (Pre-release)
## Changes since v4.0.0
- [#227](https://github.com/pusher/oauth2_proxy/pull/227) Add Keycloak provider (@Ofinka)
# v4.0.0
## Release Highlights
- Documentation is now on a [microsite](https://pusher.github.io/oauth2_proxy/)
- Health check logging can now be disabled for quieter logs
- Authorization Header JWTs can now be verified by the proxy to skip authentication for machine users
- Sessions can now be stored in Redis. This reduces refresh failures and uses smaller cookies (Recommended for those using OIDC refreshing)
- Logging overhaul allows customisable logging formats
## Important Notes
- This release includes a number of breaking changes that will require users to
reconfigure their proxies. Please read the Breaking Changes below thoroughly.
## Breaking Changes
- [#231](https://github.com/pusher/oauth2_proxy/pull/231) Rework GitLab provider
- This PR changes the configuration options for the GitLab provider to use
a self-hosted instance. You now need to specify a `-oidc-issuer-url` rather than
explicit `-login-url`, `-redeem-url` and `-validate-url` parameters.
- [#186](https://github.com/pusher/oauth2_proxy/pull/186) Make config consistent
- This PR changes configuration options so that all flags have a config counterpart
of the same name but with underscores (`_`) in place of hyphens (`-`).
This change affects the following flags:
- The `--tls-key` flag is now `--tls-key-file` to be consistent with existing
file flags and the existing config and environment settings
- The `--tls-cert` flag is now `--tls-cert-file` to be consistent with existing
file flags and the existing config and environment settings
This change affects the following existing configuration options:
- The `proxy-prefix` option is now `proxy_prefix`.
This PR changes environment variables so that all flags have an environment
counterpart of the same name but capitalised, with underscores (`_`) in place
of hyphens (`-`) and with the prefix `OAUTH2_PROXY_`.
This change affects the following existing environment variables:
- The `OAUTH2_SKIP_OIDC_DISCOVERY` environment variable is now `OAUTH2_PROXY_SKIP_OIDC_DISCOVERY`.
- The `OAUTH2_OIDC_JWKS_URL` environment variable is now `OAUTH2_PROXY_OIDC_JWKS_URL`.
- [#146](https://github.com/pusher/oauth2_proxy/pull/146) Use full email address as `User` if the auth response did not contain a `User` field
- This change modifies the contents of the `X-Forwarded-User` header supplied by the proxy for users where the auth response from the IdP did not contain
a username.
In that case, this header used to only contain the local part of the user's email address (e.g. `john.doe` for `john.doe@example.com`) but now contains
the user's full email address instead.
- [#170](https://github.com/pusher/oauth2_proxy/pull/170) Pre-built binary tarballs changed format
- The pre-built binary tarballs again match the format of the [bitly](https://github.com/bitly/oauth2_proxy) repository, where the unpacked directory
has the same name as the tarball and the binary is always named `oauth2_proxy`. This was done to restore compatibility with third-party automation
recipes like https://github.com/jhoblitt/puppet-oauth2_proxy.

# v3.1.0
## Release highlights
- Introduction of ARM releases and and general improvements to Docker builds
- Improvements to OIDC provider allowing pass-through of ID Tokens
- Multiple redirect domains can now be whitelisted
- Streamed responses are now flushed periodically
## Important notes
- If you have been using [#bitly/621](https://github.com/bitly/oauth2_proxy/pull/621)
and have cookies larger than the 4kb limit,
the cookie splitting pattern has changed and now uses `_` in place of `-` when
indexing cookies.
This will force users to reauthenticate the first time they use `v3.1.0`.
- Streamed responses will now be flushed every 1 second by default.
Previously streamed responses were flushed only when the buffer was full.
To retain the old behaviour set `--flush-interval=0`.
See [#23](https://github.com/pusher/oauth2_proxy/pull/23) for further details.

- [#24](https://github.com/pusher/oauth2_proxy/pull/24) Redirect fix (@agentgonzo)
- After a successful login, you will be redirected to your original URL rather than /
- [#35](https://github.com/pusher/oauth2_proxy/pull/35) arm and arm64 binary releases (@kskewes)
- Add armv6 and arm64 to Makefile `release` target
- [#37](https://github.com/pusher/oauth2_proxy/pull/37) cross build arm and arm64 docker images (@kskewes)

## Contributing
## OAuth Provider Configuration
Please see our [Contributing](CONTRIBUTING.md) guidelines.
You will need to register an OAuth application with a Provider (Google, GitHub or another provider), and configure it with Redirect URI(s) for the domain you intend to run `oauth2_proxy` on.
Valid providers are :
* [Google](#google-auth-provider) *default*
* [Azure](#azure-auth-provider)
* [Facebook](#facebook-auth-provider)
* [GitHub](#github-auth-provider)
* [GitLab](#gitlab-auth-provider)
* [LinkedIn](#linkedin-auth-provider)
The provider can be selected using the `provider` configuration value.
### Google Auth Provider
For Google, the registration steps are:
1. Create a new project: https://console.developers.google.com/project
2. Choose the new project from the top right project dropdown (only if another project is selected)
3. In the project Dashboard center pane, choose **"API Manager"**
4. In the left Nav pane, choose **"Credentials"**
5. In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
6. In the center pane, choose **"Credentials"** tab.
* Open the **"New credentials"** drop down
* Choose **"OAuth client ID"**
* Choose **"Web application"**
* Application name is freeform, choose something appropriate
* Authorized JavaScript origins is your domain ex: `https://internal.yourcompany.com`
* Authorized redirect URIs is the location of oauth2/callback ex: `https://internal.yourcompany.com/oauth2/callback`
* Choose **"Create"**
4. Take note of the **Client ID** and **Client Secret**
It's recommended to refresh sessions on a short interval (1h) with `cookie-refresh` setting which validates that the account is still authorized.
#### Restrict auth to specific Google groups on your domain. (optional)
1. Create a service account: https://developers.google.com/identity/protocols/OAuth2ServiceAccount and make sure to download the json file.
2. Make note of the Client ID for a future step.
3. Under "APIs & Auth", choose APIs.
4. Click on Admin SDK and then Enable API.
5. Follow the steps on https://developers.google.com/admin-sdk/directory/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account and give the client id from step 2 the following oauth scopes:
```
https://www.googleapis.com/auth/admin.directory.group.readonly
https://www.googleapis.com/auth/admin.directory.user.readonly
```
6. Follow the steps on https://support.google.com/a/answer/60757 to enable Admin API access.
7. Create or choose an existing administrative email address on the Gmail domain to assign to the ```google-admin-email``` flag. This email will be impersonated by this client to make calls to the Admin SDK. See the note on the link from step 5 for the reason why.
8. Create or choose an existing email group and set that email to the ```google-group``` flag. You can pass multiple instances of this flag with different groups
and the user will be checked against all the provided groups.
9. Lock down the permissions on the json file downloaded from step 1 so only oauth2_proxy is able to read the file and set the path to the file in the ```google-service-account-json``` flag.
10. Restart oauth2_proxy.
Note: The user is checked against the group members list on initial authentication and every time the token is refreshed ( about once an hour ).
### Azure Auth Provider
1. [Add an application](https://azure.microsoft.com/en-us/documentation/articles/active-directory-integrating-applications/) to your Azure Active Directory tenant.
2. On the App properties page provide the correct Sign-On URL ie `https://internal.yourcompany.com/oauth2/callback`
3. If applicable take note of your `TenantID` and provide it via the `--azure-tenant=<YOUR TENANT ID>` commandline option. Default the `common` tenant is used.
The Azure AD auth provider uses `openid` as it default scope. It uses `https://graph.windows.net` as a default protected resource. It call to `https://graph.windows.net/me` to get the email address of the user that logs in.
### Facebook Auth Provider
1. Create a new FB App from <https://developers.facebook.com/>
2. Under FB Login, set your Valid OAuth redirect URIs to `https://internal.yourcompany.com/oauth2/callback`
### GitHub Auth Provider
1. Create a new project: https://github.com/settings/developers
2. Under `Authorization callback URL` enter the correct url ie `https://internal.yourcompany.com/oauth2/callback`
The GitHub auth provider supports two additional parameters to restrict authentication to Organization or Team level access. Restricting by org and team is normally accompanied with `--email-domain=*`
-github-org="": restrict logins to members of this organisation
-github-team="": restrict logins to members of any of these teams (slug), separated by a comma
If you are using GitHub enterprise, make sure you set the following to the appropriate url:
-login-url="http(s)://<enterprise github host>/login/oauth/authorize"
-redeem-url="http(s)://<enterprise github host>/login/oauth/access_token"
-validate-url="http(s)://<enterprise github host>/api/v3"
### GitLab Auth Provider
Whether you are using GitLab.com or self-hosting GitLab, follow [these steps to add an application](http://doc.gitlab.com/ce/integration/oauth_provider.html)
If you are using self-hosted GitLab, make sure you set the following to the appropriate URL:
-login-url="<your gitlab url>/oauth/authorize"
-redeem-url="<your gitlab url>/oauth/token"
-validate-url="<your gitlab url>/api/v4/user"
### LinkedIn Auth Provider
For LinkedIn, the registration steps are:
1. Create a new project: https://www.linkedin.com/secure/developer
2. In the OAuth User Agreement section:
* In default scope, select r_basicprofile and r_emailaddress.
* In "OAuth 2.0 Redirect URLs", enter `https://internal.yourcompany.com/oauth2/callback`
3. Fill in the remaining required fields and Save.
4. Take note of the **Consumer Key / API Key** and **Consumer Secret / Secret Key**
### Microsoft Azure AD Provider
For adding an application to the Microsoft Azure AD follow [these steps to add an application](https://azure.microsoft.com/en-us/documentation/articles/active-directory-integrating-applications/).
Take note of your `TenantId` if applicable for your situation. The `TenantId` can be used to override the default `common` authorization server with a tenant specific server.
### OpenID Connect Provider
OpenID Connect is a spec for OAUTH 2.0 + identity that is implemented by many major providers and several open source projects. This provider was originally built against CoreOS Dex and we will use it as an example.
1. Launch a Dex instance using the [getting started guide](https://github.com/coreos/dex/blob/master/Documentation/getting-started.md).
2. Setup oauth2_proxy with the correct provider and using the default ports and callbacks.
3. Login with the fixture use in the dex guide and run the oauth2_proxy with the following args:
-provider oidc
-client-id oauth2_proxy
-client-secret proxy
-redirect-url http://127.0.0.1:4180/oauth2/callback
-oidc-issuer-url http://127.0.0.1:5556
-cookie-secure=false
-email-domain example.com
## Email Authentication
To authorize by email domain use `--email-domain=yourcompany.com`. To authorize individual email addresses use `--authenticated-emails-file=/path/to/file` with one email per line. To authorize all email addresses use `--email-domain=*`.
## Configuration
`oauth2_proxy` can be configured via [config file](#config-file), [command line options](#command-line-options) or [environment variables](#environment-variables).
To generate a strong cookie secret use `python -c 'import os,base64; print base64.urlsafe_b64encode(os.urandom(16))'`
### Config File
An example [oauth2_proxy.cfg](contrib/oauth2_proxy.cfg.example) config file is in the contrib directory. It can be used by specifying `-config=/etc/oauth2_proxy.cfg`
### Command Line Options
```
Usage of oauth2_proxy:
-approval-prompt string: OAuth approval_prompt (default "force")
-authenticated-emails-file string: authenticate against emails via file (one per line)
-azure-tenant string: go to a tenant-specific or common (tenant-independent) endpoint. (default "common")
-basic-auth-password string: the password to set when passing the HTTP Basic Auth header

See below for provider specific options
### Upstreams Configuration
`oauth2_proxy` supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as `http://127.0.0.1:8080/` for the upstream parameter, that will forward all authenticated requests to be forwarded to the upstream server. If you instead provide `http://127.0.0.1:8080/some/path/` then it will only be requests that start with `/some/path/` which are forwarded to the upstream.
Static file paths are configured as a file:// URL. `file:///var/www/static/` will serve the files from that directory at `http://[oauth2_proxy url]/var/www/static/`, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at. `file:///var/www/static/#/static/` will ie. make `/var/www/static/` available at `http://[oauth2_proxy url]/static/`.
Multiple upstreams can either be configured by supplying a comma separated list to the `-upstream` parameter, supplying the parameter multiple times or provinding a list in the [config file](#config-file). When multiple upstreams are used routing to them will be based on the path they are set up with.
### Environment variables
The following environment variables can be used in place of the corresponding command-line arguments:
- `OAUTH2_PROXY_CLIENT_ID`
- `OAUTH2_PROXY_CLIENT_SECRET`
- `OAUTH2_PROXY_COOKIE_NAME`
- `OAUTH2_PROXY_COOKIE_SECRET`
- `OAUTH2_PROXY_COOKIE_DOMAIN`
- `OAUTH2_PROXY_COOKIE_EXPIRE`
- `OAUTH2_PROXY_COOKIE_REFRESH`
- `OAUTH2_PROXY_SIGNATURE_KEY`
## SSL Configuration
There are two recommended configurations.
1) Configure SSL Termination with OAuth2 Proxy by providing a `--tls-cert=/path/to/cert.pem` and `--tls-key=/path/to/cert.key`.
The command line to run `oauth2_proxy` in this configuration would look like this:
```bash
./oauth2_proxy \
--email-domain="yourcompany.com" \
--upstream=http://127.0.0.1:8080/ \
--tls-cert=/path/to/cert.pem \
--tls-key=/path/to/cert.key \
--cookie-secret=... \
--cookie-secure=true \
--provider=... \
--client-id=... \
--client-secret=...
```
2) Configure SSL Termination with [Nginx](http://nginx.org/) (example config below), Amazon ELB, Google Cloud Platform Load Balancing, or ....
Because `oauth2_proxy` listens on `127.0.0.1:4180` by default, to listen on all interfaces (needed when using an
external load balancer like Amazon ELB or Google Platform Load Balancing) use `--http-address="0.0.0.0:4180"` or
`--http-address="http://:4180"`.
Nginx will listen on port `443` and handle SSL connections while proxying to `oauth2_proxy` on port `4180`.
`oauth2_proxy` will then authenticate requests for an upstream application. The external endpoint for this example
would be `https://internal.yourcompany.com/`.
An example Nginx config follows. Note the use of `Strict-Transport-Security` header to pin requests to SSL
via [HSTS](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security):
```
server {
listen 443 default ssl;
server_name internal.yourcompany.com;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/cert.key;
add_header Strict-Transport-Security max-age=2592000;
location / {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_connect_timeout 1;
proxy_send_timeout 30;
proxy_read_timeout 30;
}
}
```
The command line to run `oauth2_proxy` in this configuration would look like this:
```bash
./oauth2_proxy \
--email-domain="yourcompany.com" \
--upstream=http://127.0.0.1:8080/ \
--cookie-secret=... \
--cookie-secure=true \
--provider=... \
--client-id=... \
--client-secret=...
```
## Endpoint Documentation
OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The `/oauth2` prefix can be changed with the `--proxy-prefix` config variable.
* /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see [robotstxt.org](http://www.robotstxt.org/) for more info
* /ping - returns an 200 OK response
* /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
* /oauth2/start - a URL that will redirect to start the OAuth cycle
* /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
* /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the [Nginx `auth_request` directive](#nginx-auth-request)
## Request signatures
If `signature_key` is defined, proxied requests will be signed with the
`GAP-Signature` header, which is a [Hash-based Message Authentication Code
(HMAC)](https://en.wikipedia.org/wiki/Hash-based_message_authentication_code)
of selected request information and the request body [see `SIGNATURE_HEADERS`
in `oauthproxy.go`](./oauthproxy.go).
`signature_key` must be of the form `algorithm:secretkey`, (ie: `signature_key = "sha1:secret0"`)
For more information about HMAC request signature validation, read the
following:
* [Amazon Web Services: Signing and Authenticating REST
Requests](https://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html)
* [rc3.org: Using HMAC to authenticate Web service
requests](http://rc3.org/2011/12/02/using-hmac-to-authenticate-web-service-requests/)
## Logging Format
By default, OAuth2 Proxy logs requests to stdout in a format similar to Apache Combined Log.
```
<REMOTE_ADDRESS> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] <HOST_HEADER> GET <UPSTREAM_HOST> "/path/" HTTP/1.1 "<USER_AGENT>" <RESPONSE_CODE> <RESPONSE_BYTES> <REQUEST_DURATION>
```
If you require a different format than that, you can configure it with the `-request-logging-format` flag.
The default format is configured as follows:
```
{{.Client}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}
```
[See `logMessageData` in `logging_handler.go`](./logging_handler.go) for all available variables.
## Adding a new Provider
Follow the examples in the [`providers` package](providers/) to define a new
`Provider` instance. Add a new `case` to
[`providers.New()`](providers/providers.go) to allow `oauth2_proxy` to use the
new `Provider`.
## <a name="nginx-auth-request"></a>Configuring for use with the Nginx `auth_request` directive
The [Nginx `auth_request` directive](http://nginx.org/en/docs/http/ngx_http_auth_request_module.html) allows Nginx to authenticate requests via the oauth2_proxy's `/auth` endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:
```nginx
server {
listen 443 ssl;
server_name ...;
include ssl/ssl.conf;
location /oauth2/ {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-Auth-Request-Redirect $request_uri;
}
location = /oauth2/auth {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
# nginx auth_request includes headers but not body
proxy_set_header Content-Length "";
proxy_pass_request_body off;
}
location / {
auth_request /oauth2/auth;
error_page 401 = /oauth2/sign_in;
# pass information via X-User and X-Email headers to backend,
# requires running with --set-xauthrequest flag
auth_request_set $user $upstream_http_x_auth_request_user;
auth_request_set $email $upstream_http_x_auth_request_email;
proxy_set_header X-User $user;
proxy_set_header X-Email $email;
# if you enabled --cookie-refresh, this is needed for it to work with auth_request
auth_request_set $auth_cookie $upstream_http_set_cookie;
add_header Set-Cookie $auth_cookie;
proxy_pass http://backend/;
# or "root /path/to/site;" or "fastcgi_pass ..." etc
}
}
```

## OAuth Provider Configuration
You will need to register an OAuth application with a Provider (Google, GitHub or another provider), and configure it with Redirect URI(s) for the domain you intend to run `oauth2_proxy` on.
Valid providers are :
- [Google](#google-auth-provider) _default_
- [Azure](#azure-auth-provider)
- [Facebook](#facebook-auth-provider)
- [GitHub](#github-auth-provider)
- [Keycloak](#keycloak-auth-provider)
- [GitLab](#gitlab-auth-provider)
- [LinkedIn](#linkedin-auth-provider)
- [login.gov](#logingov-provider)
The provider can be selected using the `provider` configuration value.
### Google Auth Provider
For Google, the registration steps are:
1. Create a new project: https://console.developers.google.com/project
2. Choose the new project from the top right project dropdown (only if another project is selected)
3. In the project Dashboard center pane, choose **"API Manager"**
4. In the left Nav pane, choose **"Credentials"**
5. In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
6. In the center pane, choose **"Credentials"** tab.
- Open the **"New credentials"** drop down
- Choose **"OAuth client ID"**
- Choose **"Web application"**
- Application name is freeform, choose something appropriate
- Authorized JavaScript origins is your domain ex: `https://internal.yourcompany.com`
- Authorized redirect URIs is the location of oauth2/callback ex: `https://internal.yourcompany.com/oauth2/callback`
- Choose **"Create"**
7. Take note of the **Client ID** and **Client Secret**
It's recommended to refresh sessions on a short interval (1h) with `cookie-refresh` setting which validates that the account is still authorized.
#### Restrict auth to specific Google groups on your domain. (optional)
1. Create a service account: https://developers.google.com/identity/protocols/OAuth2ServiceAccount and make sure to download the json file.
2. Make note of the Client ID for a future step.
3. Under "APIs & Auth", choose APIs.
4. Click on Admin SDK and then Enable API.
5. Follow the steps on https://developers.google.com/admin-sdk/directory/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account and give the client id from step 2 the following oauth scopes:
```
https://www.googleapis.com/auth/admin.directory.group.readonly
https://www.googleapis.com/auth/admin.directory.user.readonly
```
6. Follow the steps on https://support.google.com/a/answer/60757 to enable Admin API access.
7. Create or choose an existing administrative email address on the Gmail domain to assign to the `google-admin-email` flag. This email will be impersonated by this client to make calls to the Admin SDK. See the note on the link from step 5 for the reason why.
8. Create or choose an existing email group and set that email to the `google-group` flag. You can pass multiple instances of this flag with different groups
and the user will be checked against all the provided groups.
9. Lock down the permissions on the json file downloaded from step 1 so only oauth2_proxy is able to read the file and set the path to the file in the `google-service-account-json` flag.
10. Restart oauth2_proxy.
Note: The user is checked against the group members list on initial authentication and every time the token is refreshed ( about once an hour ).
### Azure Auth Provider
1. Add an application: go to [https://portal.azure.com](https://portal.azure.com), choose **"Azure Active Directory"** in the left menu, select **"App registrations"** and then click on **"New app registration"**.
2. Pick a name and choose **"Webapp / API"** as application type. Use `https://internal.yourcompany.com` as Sign-on URL. Click **"Create"**.
3. On the **"Settings"** / **"Properties"** page of the app, pick a logo and select **"Multi-tenanted"** if you want to allow users from multiple organizations to access your app. Note down the application ID. Click **"Save"**.
4. On the **"Settings"** / **"Required Permissions"** page of the app, click on **"Windows Azure Active Directory"** and then on **"Access the directory as the signed in user"**. Hit **"Save"** and then then on **"Grant permissions"** (you might need another admin to do this).
5. On the **"Settings"** / **"Reply URLs"** page of the app, add `https://internal.yourcompanycom/oauth2/callback` for each host that you want to protect by the oauth2 proxy. Click **"Save"**.
6. On the **"Settings"** / **"Keys"** page of the app, add a new key and note down the value after hitting **"Save"**.
7. Configure the proxy with
```
--provider=azure
--client-id=<application ID from step 3>
--client-secret=<value from step 6>
```
### Facebook Auth Provider
1. Create a new FB App from <https://developers.facebook.com/>
2. Under FB Login, set your Valid OAuth redirect URIs to `https://internal.yourcompany.com/oauth2/callback`
### GitHub Auth Provider
1. Create a new project: https://github.com/settings/developers
2. Under `Authorization callback URL` enter the correct url ie `https://internal.yourcompany.com/oauth2/callback`
The GitHub auth provider supports two additional parameters to restrict authentication to Organization or Team level access. Restricting by org and team is normally accompanied with `--email-domain=*`
-github-org="": restrict logins to members of this organisation
-github-team="": restrict logins to members of any of these teams (slug), separated by a comma
If you are using GitHub enterprise, make sure you set the following to the appropriate url:
-login-url="http(s)://<enterprise github host>/login/oauth/authorize"
-redeem-url="http(s)://<enterprise github host>/login/oauth/access_token"
-validate-url="http(s)://<enterprise github host>/api/v3"
### Keycloak Auth Provider
1. Create new client in your Keycloak with **Access Type** 'confidental'.
2. Create a mapper with **Mapper Type** 'Group Membership'.
Make sure you set the following to the appropriate url:
-provider=keycloak
-client-id=<client you have created>
-client-secret=<your client's secret>
-login-url="http(s)://<keycloak host>/realms/<your realm>/protocol/openid-connect/auth"
-redeem-url="http(s)://<keycloak host>/realms/master/<your realm>/openid-connect/auth/token"
-validate-url="http(s)://<keycloak host>/realms/master/<your realm>/openid-connect/userinfo"
### GitLab Auth Provider
Whether you are using GitLab.com or self-hosting GitLab, follow [these steps to add an application](https://docs.gitlab.com/ce/integration/oauth_provider.html). Make sure to enable at least the `openid`, `profile` and `email` scopes.
Restricting by group membership is possible with the following option:
-gitlab-group="": restrict logins to members of any of these groups (slug), separated by a comma
If you are using self-hosted GitLab, make sure you set the following to the appropriate URL:
-oidc-issuer-url="<your gitlab url>"
### LinkedIn Auth Provider
For LinkedIn, the registration steps are:
1. Create a new project: https://www.linkedin.com/secure/developer
2. In the OAuth User Agreement section:
- In default scope, select r_basicprofile and r_emailaddress.
- In "OAuth 2.0 Redirect URLs", enter `https://internal.yourcompany.com/oauth2/callback`
3. Fill in the remaining required fields and Save.
4. Take note of the **Consumer Key / API Key** and **Consumer Secret / Secret Key**
### Microsoft Azure AD Provider
For adding an application to the Microsoft Azure AD follow [these steps to add an application](https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app).
Take note of your `TenantId` if applicable for your situation. The `TenantId` can be used to override the default `common` authorization server with a tenant specific server.
### OpenID Connect Provider
OpenID Connect is a spec for OAUTH 2.0 + identity that is implemented by many major providers and several open source projects. This provider was originally built against CoreOS Dex and we will use it as an example.
1. Launch a Dex instance using the [getting started guide](https://github.com/coreos/dex/blob/master/Documentation/getting-started.md).
2. Setup oauth2_proxy with the correct provider and using the default ports and callbacks.
3. Login with the fixture use in the dex guide and run the oauth2_proxy with the following args:
-provider oidc
-client-id oauth2_proxy
-client-secret proxy
-redirect-url http://127.0.0.1:4180/oauth2/callback
-oidc-issuer-url http://127.0.0.1:5556
-cookie-secure=false
-email-domain example.com
The OpenID Connect Provider (OIDC) can also be used to connect to other Identity Providers such as Okta. To configure the OIDC provider for Okta, perform
the following steps:
#### Configuring the OIDC Provider with Okta
1. Log in to Okta using an administrative account. It is suggested you try this in preview first, `example.oktapreview.com`
2. (OPTIONAL) If you want to configure authorization scopes and claims to be passed on to multiple applications,
you may wish to configure an authorization server for each application. Otherwise, the provided `default` will work.
* Navigate to **Security** then select **API**
* Click **Add Authorization Server**, if this option is not available you may require an additional license for a custom authorization server.
* Fill out the **Name** with something to describe the application you are protecting. e.g. 'Example App'.
* For **Audience**, pick the URL of the application you wish to protect: https://example.corp.com
* Fill out a **Description**
* Add any **Access Policies** you wish to configure to limit application access.
* The default settings will work for other options.
[See Okta documentation for more information on Authorization Servers](https://developer.okta.com/docs/guides/customize-authz-server/overview/)
3. Navigate to **Applications** then select **Add Application**.
* Select **Web** for the **Platform** setting.
* Select **OpenID Connect** and click **Create**
* Pick an **Application Name** such as `Example App`.
* Set the **Login redirect URI** to `https://example.corp.com`.
* Under **General** set the **Allowed grant types** to `Authorization Code` and `Refresh Token`.
* Leave the rest as default, taking note of the `Client ID` and `Client Secret`.
* Under **Assignments** select the users or groups you wish to access your application.
4. Create a configuration file like the following:
```
provider = "oidc"
redirect_url = "https://example.corp.com"
oidc_issuer_url = "https://corp.okta.com/oauth2/abCd1234"
upstreams = [
"https://example.corp.com"
]
email_domains = [
"corp.com"
]
client_id = "XXXXX"
client_secret = "YYYYY"
pass_access_token = true
cookie_secret = "ZZZZZ"
skip_provider_button = true
```
The `oidc_issuer_url` is based on URL from your **Authorization Server**'s **Issuer** field in step 2, or simply https://corp.okta.com
The `client_id` and `client_secret` are configured in the application settings.
Generate a unique `client_secret` to encrypt the cookie.
Then you can start the oauth2_proxy with `./oauth2_proxy -config /etc/example.cfg`
### login.gov Provider
login.gov is an OIDC provider for the US Government.
If you are a US Government agency, you can contact the login.gov team through the contact information
that you can find on https://login.gov/developers/ and work with them to understand how to get login.gov
accounts for integration/test and production access.
A developer guide is available here: https://developers.login.gov/, though this proxy handles everything
but the data you need to create to register your application in the login.gov dashboard.
As a demo, we will assume that you are running your application that you want to secure locally on
http://localhost:3000/, that you will be starting your proxy up on http://localhost:4180/, and that
you have an agency integration account for testing.
First, register your application in the dashboard. The important bits are:
* Identity protocol: make this `Openid connect`
* Issuer: do what they say for OpenID Connect. We will refer to this string as `${LOGINGOV_ISSUER}`.
* Public key: This is a self-signed certificate in .pem format generated from a 2048 bit RSA private key.
A quick way to do this is `openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3650 -nodes -subj '/C=US/ST=Washington/L=DC/O=GSA/OU=18F/CN=localhost'`,
The contents of the `key.pem` shall be referred to as `${OAUTH2_PROXY_JWT_KEY}`.
* Return to App URL: Make this be `http://localhost:4180/`
* Redirect URIs: Make this be `http://localhost:4180/oauth2/callback`.
* Attribute Bundle: Make sure that email is selected.
Now start the proxy up with the following options:
```
./oauth2_proxy -provider login.gov \
-client-id=${LOGINGOV_ISSUER} \
-redirect-url=http://localhost:4180/oauth2/callback \
-oidc-issuer-url=https://idp.int.identitysandbox.gov/ \
-cookie-secure=false \
-email-domain=gsa.gov \
-upstream=http://localhost:3000/ \
-cookie-secret=somerandomstring12341234567890AB \
-cookie-domain=localhost \
-skip-provider-button=true \
-pubjwk-url=https://idp.int.identitysandbox.gov/api/openid_connect/certs \
-profile-url=https://idp.int.identitysandbox.gov/api/openid_connect/userinfo \
-jwt-key="${OAUTH2_PROXY_JWT_KEY}"
```
You can also set all these options with environment variables, for use in cloud/docker environments.
One tricky thing that you may encounter is that some cloud environments will pass in environment
variables in a docker env-file, which does not allow multiline variables like a PEM file.
If you encounter this, then you can create a `jwt_signing_key.pem` file in the top level
directory of the repo which contains the key in PEM format and then do your docker build.
The docker build process will copy that file into your image which you can then access by
setting the `OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem`
environment variable, or by setting `-jwt-key-file=/etc/ssl/private/jwt_signing_key.pem` on the commandline.
Once it is running, you should be able to go to `http://localhost:4180/` in your browser,
get authenticated by the login.gov integration server, and then get proxied on to your
application running on `http://localhost:3000/`. In a real deployment, you would secure
your application with a firewall or something so that it was only accessible from the
proxy, and you would use real hostnames everywhere.
#### Skip OIDC discovery
Some providers do not support OIDC discovery via their issuer URL, so oauth2_proxy cannot simply grab the authorization, token and jwks URI endpoints from the provider's metadata.
In this case, you can set the `-skip-oidc-discovery` option, and supply those required endpoints manually:
```
-provider oidc
-client-id oauth2_proxy
-client-secret proxy
-redirect-url http://127.0.0.1:4180/oauth2/callback
-oidc-issuer-url http://127.0.0.1:5556
-skip-oidc-discovery
-login-url http://127.0.0.1:5556/authorize
-redeem-url http://127.0.0.1:5556/token
-oidc-jwks-url http://127.0.0.1:5556/keys
-cookie-secure=false
-email-domain example.com
```
## Email Authentication
To authorize by email domain use `--email-domain=yourcompany.com`. To authorize individual email addresses use `--authenticated-emails-file=/path/to/file` with one email per line. To authorize all email addresses use `--email-domain=*`.
## Adding a new Provider
Follow the examples in the [`providers` package]({{ site.gitweb }}/providers/) to define a new
`Provider` instance. Add a new `case` to
[`providers.New()`]({{ site.gitweb }}/providers/providers.go) to allow `oauth2_proxy` to use the
new `Provider`.

## SSL Configuration
There are two recommended configurations.
1. Configure SSL Termination with OAuth2 Proxy by providing a `--tls-cert-file=/path/to/cert.pem` and `--tls-key-file=/path/to/cert.key`.
The command line to run `oauth2_proxy` in this configuration would look like this:
```bash
./oauth2_proxy \
--email-domain="yourcompany.com" \
--upstream=http://127.0.0.1:8080/ \
--tls-cert-file=/path/to/cert.pem \
--tls-key-file=/path/to/cert.key \
--cookie-secret=... \
--cookie-secure=true \
--provider=... \
--client-id=... \
--client-secret=...
```
2. Configure SSL Termination with [Nginx](http://nginx.org/) (example config below), Amazon ELB, Google Cloud Platform Load Balancing, or ....
Because `oauth2_proxy` listens on `127.0.0.1:4180` by default, to listen on all interfaces (needed when using an
external load balancer like Amazon ELB or Google Platform Load Balancing) use `--http-address="0.0.0.0:4180"` or
`--http-address="http://:4180"`.
Nginx will listen on port `443` and handle SSL connections while proxying to `oauth2_proxy` on port `4180`.
`oauth2_proxy` will then authenticate requests for an upstream application. The external endpoint for this example
would be `https://internal.yourcompany.com/`.
An example Nginx config follows. Note the use of `Strict-Transport-Security` header to pin requests to SSL
via [HSTS](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security):
```
server {
listen 443 default ssl;
server_name internal.yourcompany.com;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/cert.key;
add_header Strict-Transport-Security max-age=2592000;
location / {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_connect_timeout 1;
proxy_send_timeout 30;
proxy_read_timeout 30;
}
}
```
The command line to run `oauth2_proxy` in this configuration would look like this:
```bash
./oauth2_proxy \
--email-domain="yourcompany.com" \
--upstream=http://127.0.0.1:8080/ \
--cookie-secret=... \
--cookie-secure=true \
--provider=... \
--client-id=... \
--client-secret=...
```

## Endpoint Documentation
OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The `/oauth2` prefix can be changed with the `--proxy-prefix` config variable.
- /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see [robotstxt.org](http://www.robotstxt.org/) for more info
- /ping - returns a 200 OK response, which is intended for use with health checks
- /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
- /oauth2/start - a URL that will redirect to start the OAuth cycle
- /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
- /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the [Nginx `auth_request` directive](#nginx-auth-request)

## Request signatures
If `signature_key` is defined, proxied requests will be signed with the
`GAP-Signature` header, which is a [Hash-based Message Authentication Code
(HMAC)](https://en.wikipedia.org/wiki/Hash-based_message_authentication_code)
of selected request information and the request body [see `SIGNATURE_HEADERS`
in `oauthproxy.go`]({{ site.gitweb }}/oauthproxy.go).
`signature_key` must be of the form `algorithm:secretkey`, (ie: `signature_key = "sha1:secret0"`)
For more information about HMAC request signature validation, read the
following:
- [Amazon Web Services: Signing and Authenticating REST
Requests](https://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html)
- [rc3.org: Using HMAC to authenticate Web service
requests](http://rc3.org/2011/12/02/using-hmac-to-authenticate-web-service-requests/)

See below for provider specific options
### Upstreams Configuration
`oauth2_proxy` supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as `http://127.0.0.1:8080/` for the upstream parameter, that will forward all authenticated requests to be forwarded to the upstream server. If you instead provide `http://127.0.0.1:8080/some/path/` then it will only be requests that start with `/some/path/` which are forwarded to the upstream.
Static file paths are configured as a file:// URL. `file:///var/www/static/` will serve the files from that directory at `http://[oauth2_proxy url]/var/www/static/`, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at. `file:///var/www/static/#/static/` will ie. make `/var/www/static/` available at `http://[oauth2_proxy url]/static/`.
Multiple upstreams can either be configured by supplying a comma separated list to the `-upstream` parameter, supplying the parameter multiple times or provinding a list in the [config file](#config-file). When multiple upstreams are used routing to them will be based on the path they are set up with.
### Environment variables
Every command line argument can be specified as an environment variable by
prefixing it with `OAUTH2_PROXY_`, capitalising it, and replacing hypens (`-`)
with underscores (`_`). If the argument can be specified multiple times, the
environment variable should be plural (trailing `S`).
This is particularly useful for storing secrets outside of a configuration file
or the command line.
For example, the `--cookie-secret` flag becomes `OAUTH2_PROXY_COOKIE_SECRET`,
and the `--email-domain` flag becomes `OAUTH2_PROXY_EMAIL_DOMAINS`.
## Logging Configuration
By default, OAuth2 Proxy logs all output to stdout. Logging can be configured to output to a rotating log file using the `-logging-filename` command.
If logging to a file you can also configure the maximum file size (`-logging-max-size`), age (`-logging-max-age`), max backup logs (`-logging-max-backups`), and if backup logs should be compressed (`-logging-compress`).
There are three different types of logging: standard, authentication, and HTTP requests. These can each be enabled or disabled with `-standard-logging`, `-auth-logging`, and `-request-logging`.
Each type of logging has their own configurable format and variables. By default these formats are similar to the Apache Combined Log.
Logging of requests to the `/ping` endpoint can be disabled with `-silence-ping-logging` reducing log volume. This flag appends the `-ping-path` to `-exclude-logging-paths`.
### Auth Log Format
Authentication logs are logs which are guaranteed to contain a username or email address of a user attempting to authenticate. These logs are output by default in the below format:
```
<REMOTE_ADDRESS> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] [<STATUS>] <MESSAGE>
```
The status block will contain one of the below strings:
- `AuthSuccess` If a user has authenticated successfully by any method
- `AuthFailure` If the user failed to authenticate explicitly
- `AuthError` If there was an unexpected error during authentication
If you require a different format than that, you can configure it with the `-auth-logging-format` flag.
The default format is configured as follows:
```
{% raw %}{{.Client}} - {{.Username}} [{{.Timestamp}}] [{{.Status}}] {{.Message}}{% endraw %}
```
Available variables for auth logging:
| Variable | Example | Description |
| --- | --- | --- |
| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists. |
| Host | domain.com | The value of the Host header. |
| Protocol | HTTP/1.0 | The request protocol. |
| RequestMethod | GET | The request method. |
| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
| UserAgent | - | The full user agent as reported by the requesting client. |
| Username | username@email.com | The email or username of the auth request. |
| Status | AuthSuccess | The status of the auth request. See above for details. |
| Message | Authenticated via OAuth2 | The details of the auth attempt. |
### Request Log Format
HTTP request logs will output by default in the below format:
```
<REMOTE_ADDRESS> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] <HOST_HEADER> GET <UPSTREAM_HOST> "/path/" HTTP/1.1 "<USER_AGENT>" <RESPONSE_CODE> <RESPONSE_BYTES> <REQUEST_DURATION>
```
If you require a different format than that, you can configure it with the `-request-logging-format` flag.
The default format is configured as follows:
```
{% raw %}{{.Client}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}{% endraw %}
```
Available variables for request logging:
| Variable | Example | Description |
| --- | --- | --- |
| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists. |
| Host | domain.com | The value of the Host header. |
| Protocol | HTTP/1.0 | The request protocol. |
| RequestDuration | 0.001 | The time in seconds that a request took to process. |
| RequestMethod | GET | The request method. |
| RequestURI | "/oauth2/auth" | The URI path of the request. |
| ResponseSize | 12 | The size in bytes of the response. |
| StatusCode | 200 | The HTTP status code of the response. |
| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
| Upstream | - | The upstream data of the HTTP request. |
| UserAgent | - | The full user agent as reported by the requesting client. |
| Username | username@email.com | The email or username of the auth request. |
### Standard Log Format
All other logging that is not covered by the above two types of logging will be output in this standard logging format. This includes configuration information at startup and errors that occur outside of a session. The default format is below:
```
[19/Mar/2015:17:20:19 -0400] [main.go:40] <MESSAGE>
```
If you require a different format than that, you can configure it with the `-standard-logging-format` flag. The default format is configured as follows:
```
{% raw %}[{{.Timestamp}}] [{{.File}}] {{.Message}}{% endraw %}
```
Available variables for standard logging:
| Variable | Example | Description |
| --- | --- | --- |
| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
| File | main.go:40 | The file and line number of the logging statement. |
| Message | HTTP: listening on 127.0.0.1:4180 | The details of the log statement. |
## <a name="nginx-auth-request"></a>Configuring for use with the Nginx `auth_request` directive
The [Nginx `auth_request` directive](http://nginx.org/en/docs/http/ngx_http_auth_request_module.html) allows Nginx to authenticate requests via the oauth2_proxy's `/auth` endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:
```nginx
server {
listen 443 ssl;
server_name ...;
include ssl/ssl.conf;
location /oauth2/ {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-Auth-Request-Redirect $request_uri;
}
location = /oauth2/auth {
proxy_pass http://127.0.0.1:4180;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
# nginx auth_request includes headers but not body
proxy_set_header Content-Length "";
proxy_pass_request_body off;
}
location / {
auth_request /oauth2/auth;
error_page 401 = /oauth2/sign_in;
# pass information via X-User and X-Email headers to backend,
# requires running with --set-xauthrequest flag
auth_request_set $user $upstream_http_x_auth_request_user;
auth_request_set $email $upstream_http_x_auth_request_email;
proxy_set_header X-User $user;
proxy_set_header X-Email $email;
# if you enabled --pass-access-token, this will pass the token to the backend
auth_request_set $token $upstream_http_x_auth_request_access_token;
proxy_set_header X-Access-Token $token;
# if you enabled --cookie-refresh, this is needed for it to work with auth_request
auth_request_set $auth_cookie $upstream_http_set_cookie;
add_header Set-Cookie $auth_cookie;
# When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
# limit and so the OAuth2 Proxy splits these into multiple parts.
# Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
# so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;
# Extract the Cookie attributes from the first Set-Cookie header and append them
# to the second part ($upstream_cookie_* variables only contain the raw cookie content)
if ($auth_cookie ~* "(; .*)") {
set $auth_cookie_name_0 $auth_cookie;
set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
}
# Send both Set-Cookie headers now if there was a second part
if ($auth_cookie_name_upstream_1) {
add_header Set-Cookie $auth_cookie_name_0;
add_header Set-Cookie $auth_cookie_name_1;
}
proxy_pass http://backend/;
# or "root /path/to/site;" or "fastcgi_pass ..." etc
}
}
```
If you use ingress-nginx in Kubernetes (which includes the Lua module), you also can use the following configuration snippet for your Ingress:
```yaml
nginx.ingress.kubernetes.io/auth-response-headers: Authorization
nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$request_uri
nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
nginx.ingress.kubernetes.io/configuration-snippet: |
auth_request_set $name_upstream_1 $upstream_cookie_name_1;
access_by_lua_block {
if ngx.var.name_upstream_1 ~= "" then
ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
end
}
```
You have to substitute *name* with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

## Sessions
Sessions allow a user's authentication to be tracked between multiple HTTP
requests to a service.
The OAuth2 Proxy uses a Cookie to track user sessions and will store the session
data in one of the available session storage backends.
At present the available backends are (as passed to `--session-store-type`):
- [cookie](#cookie-storage) (default)
- [redis](#redis-storage)
### Cookie Storage
The Cookie storage backend is the default backend implementation and has
been used in the OAuth2 Proxy historically.
With the Cookie storage backend, all session information is stored in client
side cookies and transferred with each and every request.
The following should be known when using this implementation:
- Since all state is stored client side, this storage backend means that the OAuth2 Proxy is completely stateless
- Cookies are signed server side to prevent modification client-side
- It is recommended to set a `cookie-secret` which will ensure data is encrypted within the cookie data.
- Since multiple requests can be made concurrently to the OAuth2 Proxy, this session implementation
cannot lock sessions and while updating and refreshing sessions, there can be conflicts which force
users to re-authenticate
### Redis Storage
The Redis Storage backend stores sessions, encrypted, in redis. Instead sending all the information
back the the client for storage, as in the [Cookie storage](cookie-storage), a ticket is sent back
to the user as the cookie value instead.
A ticket is composed as the following:
`{CookieName}-{ticketID}.{secret}`
Where:
- The `CookieName` is the OAuth2 cookie name (_oauth2_proxy by default)
- The `ticketID` is a 128 bit random number, hex-encoded
- The `secret` is a 128 bit random number, base64url encoded (no padding). The secret is unique for every session.
- The pair of `{CookieName}-{ticketID}` comprises a ticket handle, and thus, the redis key
to which the session is stored. The encoded session is encrypted with the secret and stored
in redis via the `SETEX` command.
Encrypting every session uniquely protects the refresh/access/id tokens stored in the session from
disclosure.
#### Usage
When using the redis store, specify `--session-store-type=redis` as well as the Redis connection URL, via
`--redis-connection-url=redis://host[:port][/db-number]`.
You may also configure the store for Redis Sentinel. In this case, you will want to use the
`--redis-use-sentinel=true` flag, as well as configure the flags `--redis-sentinel-master-name`
and `--redis-sentinel-connection-urls` appropriately.
