[Samba] new server: NT_STATUS_LOGON_FAILURE

I've googled, RTFMed, and I still can't fix this. Hoping someone here 
can offer a suggestion. I'm learning, so please explain a little if you can.

I installed samba on a Ubuntu 5.10 machine (named mog). My XP machine 
"sees" it, but the username/password dialog fails.

I've traced it down to what I think is an authentication problem:

mat at mog:/etc/samba$ smbclient -L mog -U mat
Password: <I enter my password here>
session setup failed: NT_STATUS_LOGON_FAILURE

If I replace -U mat with -N I get a typical smbclient -L listing, so I 
know something is working.

Another fact is that I have an older Ubuntu (Hoary) machine that also 
serves samba and works. I copied its /etc/samba/smb.conf to the machine 
having trouble; the two machines are the same (config, username, and 
password). Right now the workgroup names are different on the two 
machines, but that didn't make a difference.

I'm stumped.
