Hi there ! I'm using Samba 2.2.3a with Openldap 2.X and the IDEALX tools (smbldap-useradd.pl etc...) When i connect to my samba server from any Windows 2000 workstation through the Network Browser providing any user account (login/password) stored into my ldap directory it Works !!!!! Next i create an account for a new computer like this "smbldap-useradd.pl -w station1" But when i try to join this windows 2000 workstation into my domain providing the administrator account it fails with a message like this : " An error as occured while trying to join the domain "DOMAIN" : The mapping between the accounts names and the security IDs have not been performed" This is a translation from the french message OK !!!! Please help me !!! sam.
