Thanks a lot for your helpful message. We finally managed to open 
offline XP session by specifying "SERVEUR\username" instead of "username"

Now the server has been repaired and I checked the accounts with 
pdbedit: all users except the lucky one have the domain set to the 
server name instead of the WORKGROUP smb.conf parameter value.

Best regards
