Before You Begin

Common Notes

You are required to utilize a unique client id for every client.
The client id on this page is merely an example and you can theoretically use any alphanumeric string.
You should not use the client secret in this example, We strongly recommend reading the Generating Client Secrets guide instead.

Assumptions

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 1.0 Provider:

Add the Omnibus OpenID Connect 1.0 OmniAuth configuration to gitlab.rb:

gitlab_rails['omniauth_providers'] = [
  {
    name: "openid_connect",
    label: "Authelia",
    icon: "https://www.authelia.com/images/branding/logo-cropped.png",
    args: {
      name: "openid_connect",
      scope: ["openid","profile","email","groups"],
      response_type: "code",
      issuer: "https://auth.example.com",
      discovery: true,
      client_auth_method: "query",
      uid_field: "preferred_username",
      send_scope_to_token_endpoint: "false",
      client_options: {
        identifier: "gitlab",
        secret: "gitlab_client_secret",
        redirect_uri: "https://gitlab.example.com/users/auth/openid_connect/callback"
      }
    }
  }
]

Authelia

The following YAML configuration is an example Authelia client configuration for use with GitLab which will operate with the above example:

- id: gitlab
  description: GitLab
  secret: '$plaintext$gitlab_client_secret'
  public: false
  authorization_policy: two_factor
  redirect_uris:
    - https://gitlab.example.com/users/auth/openid_connect/callback
