SBS4.5 with Samba PDC

[Curtis Vaughan <curtis@npc-usa.com>]

Has anyone made a Samba server the PDC for a Windows environment with 
SBS4.5?  My concern is that SBS4.5 is going to have problem with 
relinquishing its PDC role.  As I understand, SBS4.5 does not recognize 
any other PDC.  But that's with respect to a Windows environment.  If I 
raise the OS level of the Samba server high enough would it "overrule" 
SBS 4.5?
