If I missed an existing thread about this - I'm apologizing ahead of time. I don't see anything.... I'm now using 10.6 server as a PDC in a few windows environments. I have no mac clients, all windows so I need that AD/PDC support. It would appear that 10.7 will let you bind to an existing AD domain or share files to windows clients. It won't act as PDC on its own. So, I can't stay with 10.6 server as its version of SAMBA doesn't support Vista or 7, and I can't move to 10.7 as it doesn't support any windows domain logon. Or does it? I just wanted to check before I start moving everyone back to windows servers. Is binding my only option? Did they remove the PDC feature altogether? I need some centralized directory control whether its from AD or OD.
