Microsoft Azure OAuth2 OmniAuth Provider

To enable the Microsoft Azure OAuth2 OmniAuth provider, you must register your application with Azure. Azure generates a client ID and secret key for you to use.

Sign in to the Azure Portal, and follow the instructions in the Microsoft Quickstart documentation.

As you go through the Microsoft procedure, keep the following in mind:

  • If you have multiple instances of Azure Active Directory, you can switch to the desired tenant.
  • You're setting up a Web application.
  • The redirect URI requires the URL of the Azure OAuth callback of your GitLab installation. For example, https://gitlab.mycompany.com/users/auth/azure_oauth2/callback. The type dropdown should be set to Web.
  • The client ID and client secret are terms associated with OAuth 2. In some Microsoft documentation, the terms may be listed as Application ID and Application Secret.
  • If you need to generate a new client secret, follow the Microsoft documentation for creating a new application secret.
  • Save the client ID and client secret for your new app, as the client secret is only displayed one time.
  1. On your GitLab server, open the configuration file.

    For Omnibus GitLab:

    sudo editor /etc/gitlab/gitlab.rb
    

    For installations from source:

    cd /home/git/gitlab
    
    sudo -u git -H editor config/gitlab.yml
    
  2. Refer to Initial OmniAuth Configuration for initial settings.

  3. Add the provider configuration:

    For Omnibus GitLab:

    gitlab_rails['omniauth_providers'] = [
      {
        "name" => "azure_oauth2",
        "args" => {
          "client_id" => "CLIENT ID",
          "client_secret" => "CLIENT SECRET",
          "tenant_id" => "TENANT ID",
        }
      }
    ]
    

    For installations from source:

    - { name: 'azure_oauth2',
      args: { client_id: "CLIENT ID",
      client_secret: "CLIENT SECRET",
      tenant_id: "TENANT ID" } }
    

    The base_azure_url is optional and can be added for different locales; such as base_azure_url: "https://login.microsoftonline.de".

  4. Replace CLIENT ID, CLIENT SECRET and TENANT ID with the values you got above.

  5. Save the configuration file.

  6. Reconfigure or restart GitLab, depending on your installation method:

On the sign-in page, you should now see a Microsoft icon below the regular sign-in form. Click the icon to begin the authentication process. Microsoft then asks you to sign in and authorize the GitLab application. If successful, you are returned to GitLab and signed in.

Read Enable OmniAuth for an Existing User for information on how existing GitLab users can connect to their newly-available Azure AD accounts.
