winbind and NT domain not allowinf authentication

[David Degouilles]

Bonjour
I'm testing winbind to allow NT domain users (my domain is WOKUP) loging in
a unix station (hostname : david).

At the login prompt, I'm entering my windows users (WOKUP\toto) and my
domain password.
All I can see is "creating home directory ..." and i'm logged out.
What is happening ?
Thanks for all clues.

Sorry for my bad english.
