It *is* a DC, if 'server role = domain controller' is in the smb.conf.

However, some parts of Samba3, which are not used in Samba4 AD operation
(eg net, testparm) do not understand that parameter.  We are working on
fixing that, so that even more parts of the Samba suite understand about
operation in AD DC mode.  Patches for a partial fix have already been
prepared, but I'm still finishing details with Amitay for a proper fix
across the full codebase.
