Enable Oath logins self hosted?

The downside of self-hosted GitLab is that users seem to register an account for each installation. Can GitLab self hosted be configured to allow logging in with OAuth accounts like the GitLab main site can?

It’d be nice if I could use my GitLab account to contribute to/report issues on any hosted Gitlab installation. I wouldn’t need to register an account for every self hosted project.

Is this possible?
