Tested Versions
Before You Begin
You are required to utilize a unique client id and a unique and random client secret for all OpenID Connect relying parties. You should not use the client secret in this example, you should randomly generate one yourself. You may also choose to utilize a different client id, it’s completely up to you.
This example makes the following assumptions:
- Application Root URL:
https://gitlab.example.com - Authelia Root URL:
https://auth.example.com - Client ID:
gitlab - Client Secret:
gitlab_client_secret
Configuration
Application
To configure GitLab to utilize Authelia as an OpenID Connect Provider:

gitlab.rb:
gitlab_rails['omniauth_providers'] = [
{

response_type: "code",
issuer: "https://auth.example.com",

}
}
}
]
