I think bad breath... ;-) noo... just joking .. sorry , ... ;-)
It is may be help full if you provide a bit more info.
Like for example
OS =
Samba version =
The smb.conf content.
And what did you setup?
AD DC server
NT4 PDC server
Standalone server?
Member server?
And based on what you already posted below.
Im guessing an AD DC setup, but with the wrong backend setup.
But you tell us..
Greetz,
