--- type: reference --- # Google Secure LDAP **(CORE ONLY)** > [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/46391) in GitLab 11.9. [Google Cloud Identity](https://cloud.google.com/identity/) provides a Secure LDAP service that can be configured with GitLab for authentication and group sync. Secure LDAP requires a slightly different configuration than standard LDAP servers. The steps below cover: - Configuring the Secure LDAP Client in the Google Admin console. - Required GitLab configuration. ## Configuring Google LDAP client 1. Navigate to and sign in as a GSuite domain administrator. 1. Go to **Apps > LDAP > Add Client**. 1. Provide an `LDAP client name` and an optional `Description`. Any descriptive values are acceptable. For example, the name could be 'GitLab' and the description could be 'GitLab LDAP Client'. Click the **Continue** button. ![Add LDAP Client Step 1](img/google_secure_ldap_add_step_1.png) 1. Set **Access Permission** according to your needs. You must choose either 'Entire domain (GitLab)' or 'Selected organizational units' for both 'Verify user credentials' and 'Read user information'. Select 'Add LDAP Client' TIP: **Tip:** If you plan to use GitLab [LDAP Group Sync](ldap-ee.md#group-sync) , turn on 'Read group information'. ![Add LDAP Client Step 2](img/google_secure_ldap_add_step_2.png) 1. Download the generated certificate. This is required for GitLab to communicate with the Google Secure LDAP service. Save the downloaded certificates for later use. After downloading, click the **Continue to Client Details** button. 1. Expand the **Service Status** section and turn the LDAP client 'ON for everyone'. After selecting 'Save', click on the 'Service Status' bar again to collapse and return to the rest of the settings. 1. Expand the **Authentication** section and choose 'Generate New Credentials'. Copy/note these credentials for later use. After selecting 'Close', click on the 'Authentication' bar again to collapse and return to the rest of the settings. Now the Google Secure LDAP Client configuration is finished. The screenshot below shows an example of the final settings. Continue on to configure GitLab. ![LDAP Client Settings](img/google_secure_ldap_client_settings.png) ## Configuring GitLab Edit GitLab configuration, inserting the access credentials and certificate obtained earlier. The following are the configuration keys that need to be modified using the values obtained during the LDAP client configuration earlier: - `bind_dn`: The access credentials username - `password`: The access credentials password - `cert`: The `.crt` file text from the downloaded certificate bundle - `key`: The `.key` file text from the downloaded certificate bundle **For Omnibus installations** 1.
