# Use AliCloud as an OmniAuth authentication provider **(FREE)**

You can enable the AliCloud OAuth 2.0 OmniAuth provider and sign in to
GitLab using your AliCloud account.

## Create an AliCloud application

Sign in to the AliCloud platform and create an application on it. AliCloud generates a client ID and secret key for you to use.

1. Sign in to the [AliCloud platform](https://account.aliyun.com/login/login.htm).

1. Go to the [OAuth application management page](https://ram.console.aliyun.com/applications).

1. Select **Create Application**.

1. Fill in the application details:

   - **Application Name**: This can be anything.
   - **Display Name**: This can be anything.
   - **Callback URL**: This URL should be formatted as `'GitLab instance URL' + '/users/auth/alicloud/callback'`. For example, `http://test.gitlab.com/users/auth/alicloud/callback`.

   Select **Save**.

1. Add OAuth scopes in the application details page:

   1. Under the **Application Name** column, select the name of the application you created. The application's details page opens.
   1. Under the **Application OAuth Scopes** tab, select **Add OAuth Scopes**.
   1. Select the **aliuid** and **profile** checkboxes.
   1. Select **OK**.

   1. Under the **App Secrets** tab, select **Create Secret**.
   1. Copy the SecretValue generated.

## Enable AliCloud 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. [Configure the initial settings](omniauth.md#configure-initial-settings).

1. Add the provider configuration. Replace `YOUR_APP_ID` with the ID on the application details page
   and `YOUR_APP_SECRET` with the **SecretValue** you got when you registered the AliCloud application.

   - **For Omnibus installations**

     ```ruby
       gitlab_rails['omniauth_providers'] = [
         {
           name: "alicloud",
           app_id: "YOUR_APP_ID",
           app_secret: "YOUR_APP_SECRET"
         }
       ]
     ```

   - **For installations from source**

     ```yaml
     - { name: 'alicloud',
         app_id: 'YOUR_APP_ID',
         app_secret: 'YOUR_APP_SECRET' }
     ```

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.
