Common Notes

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


This example makes the following assumptions:

  • Application Root URL:
  • Authelia Root URL:
  • Client ID: gitlab
  • Client Secret: gitlab_client_secret



To configure GitLab to utilize Authelia as an OpenID Connect 1.0 Provider:

  1. Add the Omnibus OpenID Connect 1.0 OmniAuth configuration to gitlab.rb:
gitlab_rails['omniauth_providers'] = [
    name: "openid_connect",
    label: "Authelia",
    icon: "",
    args: {
      name: "openid_connect",
      scope: ["openid","profile","email","groups"],
      response_type: "code",
      issuer: "",
      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: ""


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
    - openid
    - profile
    - groups
    - email
  userinfo_signing_algorithm: none
