[Samba] Login Domain Issues

[Jesse Spangenberger]

I have a very strange problem.  I have only ONE domain on my network 
which works fine. I have windows clients running Samba-3 on SuSE 9.2 
Professional. 
 
Logging on you can do DOMAIN\username instead of changing the "Log on 
to:" box.  But you can also do <anything>\username.  Thus: 
laksaslkdjf\username works.  Some reason it changes out the beginning to 
DOMAIN when it first fails.  How the word do I stop this?
 
I want to make sure it errors out if the domain is wrongly entered.
 
This is frustrating.
