With that, is it possible to create e.g. 3 domains, each with a Samba PDC (or 
emulated)? The most important thing is that still more than 5 clients can log 
on to the domains.
In my scenario, is there any benefit of the AD left?

I'm kind of experienced with the old Samba 2.2, but a complete newbie to Samba 
3.0.
