The simplest way to promulgate the account details is to copy 'files' from the server to the workstations. Copy from '/etc' 'passwd', 'groups' and 'shadow' files from the server. This should promulgate the account info, it is only three files so it does not take long. Alternatively set up NIS+. NIS+ adds security and informs each workstation of the current account information when a login is requested. However, this is a more complex system to setup and would be worth while if a large number of user accounts are been created and modified. If you are not particularly confident on UNIX I would advise you to stay away from automount, I hate automount!
