Use Atlassian Crowd as an authentication provider (deprecated)
DETAILS: Tier: Free, Premium, Ultimate Offering: Self-managed
WARNING: This feature was deprecated in GitLab 15.3 and is planned for removal in 17.0.
Authenticate to GitLab using the Atlassian Crowd OmniAuth provider. Enabling this provider also allows Crowd authentication for Git-over-https requests.
Configure a new Crowd application
-
Choose 'Applications' in the top menu, then 'Add application'.
-
Go through the 'Add application' steps, entering the appropriate details. The screenshot below shows an example configuration.
Configure GitLab
-
On your GitLab server, open the configuration file.
-
Linux package installations:
sudo editor /etc/gitlab/gitlab.rb
-
Self-compiled installations:
cd /home/git/gitlab sudo -u git -H editor config/gitlab.yml
-
-
Configure the common settings to add
crowd
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:
-
Linux package installations:
gitlab_rails['omniauth_providers'] = [ { name: "crowd", # label: "Provider name", # optional label for login button, defaults to "Crowd" args: { crowd_server_url: "CROWD_SERVER_URL", application_name: "YOUR_APP_NAME", application_password: "YOUR_APP_PASSWORD" } } ]
-
Self-compiled installations:
- { name: 'crowd', # label: 'Provider name', # optional label for login button, defaults to "Crowd" args: { crowd_server_url: 'CROWD_SERVER_URL', application_name: 'YOUR_APP_NAME', application_password: 'YOUR_APP_PASSWORD' } }
-
-
Change
CROWD_SERVER_URL
to the base URL of your Crowd server. -
Change
YOUR_APP_NAME
to the application name from Crowd applications page. -
Change
YOUR_APP_PASSWORD
to the application password you've set. -
Save the configuration file.
-
Reconfigure (Linux package installations) or restart (self-compiled installations) for the changes to take effect.
On the sign in page there should now be a Crowd tab in the sign in form.
Troubleshooting
Error: "could not authorize you from Crowd because invalid credentials"
This error sometimes occurs when a user attempts to authenticate with Crowd. The Crowd administrator should consult the Crowd log file to know the exact cause of this error message.
Ensure the Crowd users who must sign in to GitLab are authorized to the application in the Authorization step. This could be verified by trying "Authentication test" for Crowd (as of 2.11).
