Try: smbclient -L MYUNIX -N
For me that always works when asking a samba server, and almost never to a
NT machine. I have no idea why (but when it becomes important to me maybe
I'll go find out why :)

Samba uses the PDC to check valid usernames (& passwords) when security is
set to domain. At least that is what my little test shows:

cola:~/tmp>smbclient -L server -Ulocal_server_user
Password: <local_password>
session setup failed: ERRSRV - ERRbadpw
cola:~/tmp>smbclient -L server -Uadministrator
Password: <domain password>
