FWIW, I have joined Windows 2012 with Samba3/NT4 domain in the past.
However, I'm not sure if it'll work with a NT4 domain that has a dot in
the name.

That said, we made the upgrade from Samba3 to Samba4 AD, works great on
our Linux and Windows machines. But, we only store users in AD, so no
automount maps, etc.
