[Samba] Multihomed AC DC Server and subnets

[Ryan Bair]

I'll second the routing approach. Having multiple IP addresses would add a
lot of complexity. You would need to somehow return a different IP for the
DC/File server for each subnet. You could do this with BIND, but again it
would be much more complex.
