+## Configuring Group SAML on a self-managed GitLab instance **(PREMIUM ONLY)**
+
+For information on the GitLab.com implementation, please see the [SAML SSO for GitLab.com groups page](../user/group/saml_sso).
+
+Group SAML SSO helps if you need to allow access via multiple SAML identity providers, but as a multi-tenant solution is less suited to cases where you administer your own GitLab instance.
+
+To proceed with configuring Group SAML SSO instead, you'll need to enable the `group_saml` OmniAuth provider. This can be done from:
+
+- `gitlab.rb` for [Omnibus GitLab installations](#omnibus-installations).
+- `gitlab/config/gitlab.yml` for [source installations](#source-installations).
+
+### Limitations
+
+Group SAML on a self-managed instance is limited when compared to the recommended
+[instance-wide SAML](../user/group/saml_sso/index.md). The recommended solution allows you to take advantage of:

+- [LDAP compatibility](../administration/auth/ldap/index.md).
+- [LDAP Group Sync](../user/group/index.md#manage-group-memberships-via-ldap).
+- [Required groups](#required-groups).
+- [Admin groups](#admin-groups).
