[Samba] Two domains on one network?

[Roger Merritt]

I feel I should know the answer to this, but I wanted to verify. I have a 
bunch of Windows PC's running Win 2K Pro, on three subnetworks. Two of the 
subnets are served by Unix (FreeBSD) boxes running NATD, but all are joined 
to a domain being run on a Win 2K Pro server in another building on the 
campus. So far I haven't joined the two Unix boxes to the domain.

I'd like to experiment with setting one of the FreeBSD boxes up as a 
Primary Domain Controller to experiment with LDAP and roaming profiles. I 
may be going to a new job next year where I can either do it in FreeBSD or 
some version of Windows, and if I can master the tools in FreeBSD I'd 
rather. Does this sound feasible? Does it sound like a bad idea? Are there 
tools to set group policies on Windows boxes from/through Samba?
