from all three domains (they all trust each other). I can "ps -ax | grep mbd" and see both smbd and nmbd running. I can then "ps -ax | grep winbind" and see the winbind daemon running. I can "smbclient -L localhost" and see what should be shared to the LAN, as I expected it to be. I can ping, nslookup, nmblookup, etc. and everything is working fine.
