This could be a problem with Freenas 10, it uses a later version of
Samba, where by default, ntvfs is turned off.

Samba does not understand ntvfsv4 ACLs, this is where the problem lies,
you cannot provision Samba as an AD DC on ZFS.

Also, there is no such thing as an AD/PDC, a PDC is an NT4-style domain
controller. All AD domain controllers are equal, so there is no such
concept as an AD primary DC. I suppose you could refer to the initial
DC as 'The First Domain Controller I Set UP', but do you really want to
call it a 'TFDCISU' ?? ;-)
