Hello I have set up a Samba 3 PDC on RHEL4 using the tdbsam backed. I can log in as a user who has been added to the tdbsam database from a workstation. When I try to add the workstation to the domain (after breaking user connections to the server) I get "The following error occurred while trying to joining the domain xyz.com. Access denied. I havent seen any instructions in the how-tos on how to create the Administrative account on the server to accept workstations to join the domain? How do I create security groups and join them to users ie Joe is a member of managers, accounts, engineers etc? Many thanks Mike
