Use Microsoft Azure as an authentication provider (FREE SELF)

You can enable the Microsoft Azure OAuth 2.0 OmniAuth provider and sign in to GitLab with your Microsoft Azure credentials. You can configure the provider that uses the earlier Azure Active Directory v1.0 endpoint, or the provider that uses the v2.0 endpoint.

NOTE: For new projects, Microsoft suggests you use the OpenID Connect protocol, which uses the Microsoft identity platform (v2.0) endpoint.

Migrate to the OpenID Connect protocol

To migrate to the OpenID Connect protocol, see configure multiple OpenID Connect providers.

You must set the uid_field, which differs across the providers:

Provider	`uid`	Remarks
`omniauth-azure-oauth2`	`sub`	Additional attributes `oid`, `tid` are offered within the info object
`omniauth-azure-activedirectory-v2`	`oid`	You must configure `oid` as `uid_field` when migrating
`omniauth_openid_connect`	`sub`	Specify `uid_field` to use another field

To migrate from omniauth-azure-oauth2 to omniauth_openid_connect you must change the configuration:

For Omnibus installations

gitlab_rails['omniauth_providers'] = [
  {
    name: "azure_oauth2",
    # label: "Provider name", # optional label for login button, defaults to "Azure AD"
    args: {
+      name: "azure_oauth2",
+      strategy_class: "OmniAuth::Strategies::OpenIDConnect",
+      scope: ["openid", "profile", "email"],
+      response_type: "code",
+      issuer:  "https://login.microsoftonline.com/<tenant_id>/v2.0",
+      client_auth_method: "query",
+      discovery: true,
+      uid_field: "sub",
+      client_options: {
+        identifier: "<client_id>",
+        secret: "<client_secret>",
+        redirect_uri: "https://gitlab.example.com/users/auth/azure_oauth2/callback"
+      }
-      client_id: "<client_id>",
-      client_secret: "<client_secret>",
-      tenant_id: "<tenant_id>",
    }
  }
]

For installations from source

  - { name: 'azure_oauth2',
      # label: 'Provider name', # optional label for login button, defaults to "Azure AD"
-      args: { client_id: '<client_id>',
-              client_secret: '<client_secret>',
-              tenant_id: '<tenant_id>' } }
+      icon: "<custom_provider_icon>",
+      args: {
+        name: "azure_oauth2",
+        strategy_class: "OmniAuth::Strategies::OpenIDConnect",
+        scope: ["openid","profile","email"],
+        response_type: "code",
+        issuer: 'https://login.microsoftonline.com/<tenant_id>/v2.0',
+        discovery: true,
+        client_auth_method: 'query',
+        uid_field: 'sub',
+        send_scope_to_token_endpoint: "false",
+        client_options: {
+          identifier: "<client_id>",
+          secret: "<client_secret>",
+          redirect_uri: "<your_gitlab_url>/users/auth/azure_oauth2/callback"
+        }
+      }
    }

To migrate for example from omniauth-azure-activedirectory-v2 to omniauth_openid_connect you must change the configuration:

For Omnibus installations

gitlab_rails['omniauth_providers'] = [
  {
 -    name: "azure_activedirectory_v2",
    # label: "Provider name", # optional label for login button, defaults to "Azure AD v2"
    args: {
+      name: "azure_activedirectory_v2",
+      strategy_class: "OmniAuth::Strategies::OpenIDConnect",
+      scope: ["openid", "profile", "email"],
+      response_type: "code",
+      issuer:  "https://login.microsoftonline.com/<tenant_id>/v2.0",
+      client_auth_method: "query",
+      discovery: true,
+      uid_field: "oid",
+      client_options: {
+        identifier: "<client_id>",
+        secret: "<client_secret>",
+        redirect_uri: "https://gitlab.example.com/users/auth/azure_activedirectory_v2/callback"
+      }
-      client_id: "<client_id>",
-      client_secret: "<client_secret>",
-      tenant_id: "<tenant_id>",
    }
  }
]

For installations from source

  - { name: 'azure_activedirectory_v2',
      # label: 'Provider name', # optional label for login button, defaults to "Azure AD v2"
-      args: { client_id: '<client_id>',
-              client_secret: '<client_secret>',
-              tenant_id: '<tenant_id>' } }
+      icon: "<custom_provider_icon>",
+      args: {
+        name: "azure_activedirectory_v2",
+        strategy_class: "OmniAuth::Strategies::OpenIDConnect",
+        scope: ["openid","profile","email"],
+        response_type: "code",
+        issuer: 'https://login.microsoftonline.com/<tenant_id>/v2.0',
+        discovery: true,
+        client_auth_method: 'query',
+        uid_field: 'oid',
+        send_scope_to_token_endpoint: "false",
+        client_options: {
+          identifier: "<client_id>",
+          secret: "<client_secret>",
+          redirect_uri: "<your_gitlab_url>/users/auth/azure_activedirectory_v2/callback"
+        }
+      }
    }

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.

Sign in to the Azure portal.
If you have multiple Azure Active Directory tenants, switch to the desired tenant. Note the tenant ID.
Register an application 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.
Save the client ID and client secret. The client secret is only displayed once.

If required, you can 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. 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

On your GitLab server, open the configuration file.
- For Omnibus installations
```
sudo editor /etc/gitlab/gitlab.rb
```
- For installations from source
```
cd /home/git/gitlab

sudo -u git -H editor config/gitlab.yml
```
Configure the 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.

Add the provider configuration. Replace <client_id>, <client_secret>, and <tenant_id> with the values you got when you registered the Azure application.

For Omnibus installations

For the v1.0 endpoint:

gitlab_rails['omniauth_providers'] = [
  {
    name: "azure_oauth2",
    # label: "Provider name", # optional label for login button, defaults to "Azure AD"
    args: {
      client_id: "<client_id>",
      client_secret: "<client_secret>",
      tenant_id: "<tenant_id>",
    }
  }
]

For the v2.0 endpoint:

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_id>",
      "client_secret" => "<client_secret>",
      "tenant_id" => "<tenant_id>",
    }
  }
]

For alternative Azure clouds, configure base_azure_url under the args section. For example, for Azure Government Community Cloud (GCC):

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_id>",
      "client_secret" => "<client_secret>",
      "tenant_id" => "<tenant_id>",
      "base_azure_url" => "https://login.microsoftonline.us"
    }
  }
]
