About GitLab authentication
Review GitLab authentication options for Red Hat OpenShift Container Platform. Use this integration when you want users to log in with GitLab account credentials through OAuth or OpenID Connect.
If you use GitLab version 7.7.0 to 11.0, you connect using OAuth integration. If you use GitLab version 11.1 or later, you can use OpenID Connect (OIDC) to connect instead of OAuth.
