The Cookie Prefixes spec disallows the use of the `domain` attribute in cookies
if the `__Host-` prefix is used
(https://tools.ietf.org/html/draft-ietf-httpbis-cookie-prefixes-00#section-3.2).
There's no need to set it to the host by default, so make it optional. If it is
set to a non-empty value, still output a warning if it is not a suffix of the
host, as that's likely not wanted.
Fixes#352.
This is useful in Nginx auth_request mode, if a 401 handler is
configured to redirect to the sign-in page. As the request URL
does not reflect the actual URL, the value is taken from the
header "X-Auth-Request-Redirect" instead. Based on #247
This is enhancement of #173 to use "Auth Request" consistently in
the command-line option, configuration file and response headers.
It always sets the X-Auth-Request-User response header and if the
email is available, sets X-Auth-Request-Email as well.
When checking user membership against Google groups the groups are checked one
at a time and in the order that they were supplied. If one of the groups does
not exist then the checking is halted with the following error.
google.go:201: googleapi: Error 404: Resource Not Found: groupKey, notFound
None of the groups following the missing group are checked either. This means
that something as trivial as a typo in the first group will make it impossible
for anybody to login.
This change catches the 404, logs a message, and then carries on as usual. In
this way a typo will cause a particular group to stop working but will not
affect any other groups.
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 fixes https://github.com/bitly/oauth2_proxy/issues/205
* Add new boolean option -pass-user-headers
to control whether X-Forwarded-User and X-Forwarded-Email
headers will be set (as opposed to HTTP BASIC auth)
* This is required e.g. for grafana [1] where
X-Forwarded-User is needed but HTTP BASIC auth fails
(password is not known and must not be known in this scenario)
* Keep behaviour of PassBasicAuth unchanged for compatibility
