You can configure the provider that uses [the earlier Azure Active Directory v1.0 endpoint](https://learn.microsoft.com/en-us/azure/active-directory/azuread-dev/v1-protocols-oauth-code), or the provider that uses the v2.0 endpoint. NOTE: For new projects, Microsoft suggests you use the [OpenID Connect protocol](../administration/auth/oidc.md#configure-microsoft-azure), which uses the Microsoft identity platform (v2.0) endpoint. ## Register an Azure application To enable the Microsoft Azure OAuth 2.0 OmniAuth provider, you must register an Azure application and get a client ID and secret key. 1. Sign in to the [Azure portal](https://portal.azure.com). 1. If you have multiple Azure Active Directory tenants, switch to the desired tenant. Note the tenant ID. 1. [Register an application](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app) and provide the following information: - The redirect URI, which requires the URL of the Azure OAuth callback of your GitLab installation. For example: - For the v1.0 endpoint: `https://gitlab.example.com/users/auth/azure_oauth2/callback`. - For the v2.0 endpoint: `https://gitlab.example.com/users/auth/azure_activedirectory_v2/callback`. - The application type, which must be set to **Web**. 1. Save the client ID and client secret. The client secret is only displayed once. If required, you can [create a new application secret](https://learn.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal#option-2-create-a-new-application-secret). `client ID` and `client secret` are terms associated with OAuth 2.0. In some Microsoft documentation, the terms are named `Application ID` and `Application Secret`. ## Add API permissions (scopes) If you're using the v2.0 endpoint, after you create the application, [configure it to expose a web API](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-configure-app-expose-web-apis). Add the following delegated permissions under the Microsoft Graph API: - `email` - `openid` - `profile` Alternatively, add the `User.Read.All` application permission. ## Enable Microsoft OAuth in GitLab 1. On your GitLab server, open the configuration file. - **For Omnibus installations** ```shell sudo editor /etc/gitlab/gitlab.rb ``` - **For installations from source** ```shell cd /home/git/gitlab sudo -u git -H editor config/gitlab.yml ``` 1. Edit the [common configuration file settings](omniauth.md#configure-common-settings) to add `azure_oauth2` as a single sign-on provider. This enables Just-In-Time account provisioning for users who do not have an existing GitLab account. 1. Add the provider configuration. Replace ``, ``, and `` with the values you got when you registered the Azure application. - **For Omnibus installations** For the v1.0 endpoint: ```ruby gitlab_rails['omniauth_providers'] = [ { name: "azure_oauth2", # label: "Provider name", # optional label for login button, defaults to "Azure AD" args: { client_id: "", client_secret: "", tenant_id: "", } } ] ``` For the v2.0 endpoint: ```ruby gitlab_rails['omniauth_providers'] = [ { "name" => "azure_activedirectory_v2", "label" => "Provider name", # optional label for login button, defaults to "Azure AD v2" "args" => { "client_id" => "", "client_secret" => "", "tenant_id" => "", } } ] ``` For [alternative Azure clouds](https://learn.microsoft.com/en-us/azure/active-directory/develop/authentication-national-cloud), configure `base_azure_url` under the `args` section. For example, for Azure Government Community Cloud (GCC): ```ruby gitlab_rails['omniauth_providers'] = [ { "name" => "azure_activedirectory_v2", "label" => "Provider name", # optional label for login button, defaults to "Azure AD v2" "args" => { "client_id" => "", "client_secret" => "", "tenant_id" => "", "base_azure_url" => "https://login.microsoftonline.us" } } ] ``` - **For installations from source** For the v1.0 endpoint: ```yaml - { name: 'azure_oauth2', # label: 'Provider name', # optional label for login button, defaults to "Azure AD" args: { client_id: '', client_secret: '', tenant_id: '' } } ``` For the v2.0 endpoint: ```yaml - { name: 'azure_activedirectory_v2', label: 'Provider name', # optional label for login button, defaults to "Azure AD v2" args: { client_id: "", client_secret: "", tenant_id: "" } } ``` For [alternative Azure clouds](https://learn.microsoft.com/en-us/azure/active-directory/develop/authentication-national-cloud), configure `base_azure_url` under the `args` section. For example, for Azure Government Community Cloud (GCC): ```yaml - { name: 'azure_activedirectory_v2', label: 'Provider name', # optional label for login button, defaults to "Azure AD v2" args: { client_id: "", client_secret: "", tenant_id: "", base_azure_url: "https://login.microsoftonline.us" } } ``` You can also optionally add the `scope` for [OAuth 2.0 scopes](https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow) parameter to the `args` section. The default is `openid profile email`. 1. Save the configuration file. 1. [Reconfigure GitLab](../administration/restart_gitlab.md#omnibus-gitlab-reconfigure) if you installed using Omnibus, or [restart GitLab](../administration/restart_gitlab.md#installations-from-source) if you installed from source. 1. Refresh the GitLab sign-in page. A Microsoft icon should display below the sign-in form. 1. Select the icon. Sign in to Microsoft and authorize the GitLab application. Read [Enable OmniAuth for an existing user](omniauth.md#enable-omniauth-for-an-existing-user) for information on how existing GitLab users can connect to their new Azure AD accounts.
