How to setup gitlab auth

[fspindle]

After a successful installation of the server using docker with the last version from master branch (commit c2c4305), I'm unable to setup gitlab auth.

In my .env file I set

GITLAB_ENABLE=true
GITLAB_CLIENT_ID=de1bfc...
GITLAB_CLIENT_SECRET=gloas-...
GITLAB_DOMAIN=https://gitlab.com/

and I configure gitlab.com to create a user-owned application selecting api, read_user, openid, profile, email OAuth 2 Scopes. In the redirect URI I set https://my-cdash.server.fr/auth/gitlab/callback

then I run docker compose --env-file .env ...

But when I click on the Gitlab logo I'm redirected to a page with the following error

An error has occurred
The redirect URI included is not valid.

I'm wondering what I'm doing wrong. Is my redirect URI address the right one ?

@fspindle, thanks for the report. I can replicate what you're experiencing locally.

It seems like the fix is to specify the redirect URI in the configuration too. When I added an .env entry for GITLAB_REDIRECT_URI which matched the value that I set when registering the user-owned application, I didn't receive the error any more. Your block of .env would look like this:

GITLAB_ENABLE=true
GITLAB_CLIENT_ID=de1bfc...
GITLAB_CLIENT_SECRET=gloas-...
GITLAB_DOMAIN=https://gitlab.com/
GITLAB_REDIRECT_URI=https://my-cdash.server.fr/auth/gitlab/callback

Please give that a try and let me know if you can log in. I'll do some digging on my end to determine why Socialite needs the redirect_uri in the authorize call when I would expect GitLab's configured value to handle it.

And just for completeness sake: yes. The redirect URL that you've set up is the correct one.
