After following the guide to join the samba4 host to a domain using winbind, I noticed that the prepended domain is not available when using commands such as id or getent passwd. This was optional using Samba3/winbind. I have a VDI solution that I'm trying to integrate with Samba4 that requires the domain be prepended for single sign-on. If you use Centrify or Likewise Open to join an external domain, the aforementioned commands will show you the domain as well as the username.
