# Google Secure LDAP **(FREE SELF)**
2020-06-23 00:09:42 +05:30
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/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:
2021-11-18 22:05:49 +05:30
- Configuring the Secure LDAP Client in the Google administrator console.
2020-06-23 00:09:42 +05:30
- Required GitLab configuration.
## Configuring Google LDAP client
2021-04-17 20:07:23 +05:30
1. Go to < https: // admin . google . com / Dashboard > and sign in as a Google Workspace domain administrator.
2020-06-23 00:09:42 +05:30
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.
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'
2021-02-22 17:27:13 +05:30
NOTE:
2021-12-11 22:18:48 +05:30
If you plan to use GitLab [LDAP Group Sync ](ldap_synchronization.md#group-sync )
2020-06-23 00:09:42 +05:30
, turn on 'Read group information'.
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.
## 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. Edit `/etc/gitlab/gitlab.rb` :
```ruby
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load < < -EOS # remember to close this block with ' EOS ' below
main: # 'main' is the GitLab 'provider ID' of this LDAP server
label: 'Google Secure LDAP'
host: 'ldap.google.com'
port: 636
uid: 'uid'
bind_dn: 'DizzyHorse'
password: 'd6V5H8nhMUW9AuDP25abXeLd'
encryption: 'simple_tls'
verify_certificates: true

<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X` .
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->
