You can set up Single Sign-on (SSO) with GitLab SaaS or a self-hosted GitLab for your team. This section helps you to create an OIDC application with GitLab. The Client ID, Client Secret, and Issuer URL of this OIDC application are required to setup SSO in Ona. See the Step-by-step guide for the general instructions.

​
Prerequisites

As prerequisites you will need the following:
  • If you are setting up SSO with a self-hosted GitLab, make sure you have Admin permissions on that GitLab installation, or work together with the administrator.
  • If you are setting up SSO with GitLab SaaS (gitlab.com), it is advised to create the OIDC application in a group, so please make sure you have Group Admin permissions on that group.
