Authentication for Github Enterprise is customisable. At my organisation we use LDAP, but it has built-in auth and a few others IIRC.
The enterprise product is stand-alone, it doesn't talk to the cloud version.
That said, my understanding is that authentication even for Github Enterprise is done through Github itself. (Someone please correct me if I'm wrong)
