GitLab authentication and authorization (FREE SELF)
GitLab integrates with a number of OmniAuth providers, and the following external authentication and authorization providers:
- LDAP: Includes Active Directory, Apple Open Directory, Open LDAP, and 389 Server.
- SAML for GitLab.com groups (PREMIUM SAAS)
- Smartcard (PREMIUM SELF)
NOTE: UltraAuth has removed their software which supports OmniAuth integration. We have therefore removed all references to UltraAuth integration.
