Since I'm no longer with 18F, I've re-released hmacauth under the ISC
license as opposed to the previous CC0 license. There have been no
changes to the hmacauth code itself, and all tests still pass.
See the README for usage with Dex or any other OIDC provider.
To test run a backend:
python3 -m http.server
Run dex and modify the example config with the proxy callback:
go get github.com/coreos/dex/cmd/dex
cd $GOPATH/src/github.com/coreos/dex
sed -i.bak \
's|http://127.0.0.1:5555/callback|http://127.0.0.1:5555/oauth2/callback|g' \
examples/config-dev.yaml
make
./bin/dex serve examples/config-dev.yaml
Then run the oauth2_proxy
oauth2_proxy \
--oidc-issuer-url http://127.0.0.1:5556/dex \
--upstream http://localhost:8000 \
--client-id example-app \
--client-secret ZXhhbXBsZS1hcHAtc2VjcmV0 \
--cookie-secret foo \
--email-domain '*' \
--http-address http://127.0.0.1:5555 \
--redirect-url http://127.0.0.1:5555/oauth2/callback \
--cookie-secure=false
Login with the username/password "admin@example.com:password"
golang.org/x/oauth2/google is same repo as golang.org/x/oauth2
- this sometimes confused gpm/git
cloud.google.com/go/compute/metadata is a missing dependency
of golang.org/x/oauth2
This change extracts the UserMap class from NewValidator() so that its
LoadAuthenticatedEmailsFile() method can be called concurrently. This method
is called by a goroutine containing a fsnotify.Watcher watching the
authenticated emails file.
Watching isn't forever aborted when the authenticated emails file disappears.
The goroutine will call os.Stat() up to twenty times a second if the file is
persistently missing, but that's the pathological case, not the common one.
The common case is that some editors (including Vim) will perform a
rename-and-replace when updating a file, triggering fsnotify.Rename events,
and the file will temporarily disappear. This watcher goroutine handles that
case.
Also, on some platforms (notably Arch Linux), a remove will be preceded by a
fsnotify.Chmod, causing a race between the upcoming fsnotify.Remove and the
call to UserMap.LoadAuthenticatedEmailsFile(). Hence, we treat fsnotify.Chmod
the same as fsnotify.Remove and fsnotify.Rename. There's no significant
penalty to re-adding a file to the watcher.
