Assuming you are dealing with fully Active-Directory integrated servers,
then the most effective solution would be to assign two IP addresses to
the same box, and run two separate instances of Samba - each with a
different config.


one instance of winbind (I'm assuming both servers are part of the same
AD realm)
smbd -D -s /etc/samba/smb-1.conf
nmbd -D -s /etc/samba/smb-1.conf
smbd -D -s /etc/samba/smb-2.conf
nmbd -D -s /etc/samba/smb-2.conf

smb-1.conf and smb-2.conf define the different hostnames, shares and
sets "bind interfaces only = Yes" and uses the
"interfaces = eth:?" option to tell each instance what IP
address/interface it needs to exclusively bind to.

I just went through the same exercise - and the above works well for us.
Kerberos really wants to stop you assigning multiple names to the same
token (at least I had huge trouble getting it to work correctly), so
mapping everything to separate IPs is the cleanest IMHO.
