The Samba documentation states quite clearly that is only capable of functioning as an NT4 style Primary Domain Controller and can not function as an Active Directory server. I manage a group of mixed systems (windows xp workstations and linux servers of various flavors), and looking to centralize authentication of various server applications as well as the client workstations. I am considering setting up a Samba server, but I can't find a feature break down between what would be offered by a PDC and an ADS to aid me in deciding if a Samba server would satisfy my goals. Does anyone know where I could find such a feature comparison?
Edit: The workstations are not currently on a domain. What ever active directory/samba configuration I introduce will be our group's initial foray into centralized authentication. This means setting up a Windows Server domain controller is a feasible option, but I'd prefer to do it with Samba as I am more Linux savy.
