Hi ! Configuration is the following: samba3-beta3 as PDC with LDAP Backend at first thanks for your hard work. in smb.conf i added ldap machine suffix = "ou=computers" ldap user suffix = "ou=people" when trying to add a machine account with net rpc join -U Administrator the account is searched for in the ou=people container and not the ou=computers container, if i move the account dc1$ to the ou=people container everything works fine. i think the net tool should look in smb.conf to find out where to search for/add machine accounts. again thank you -- Uli Iske
