Check to make sure that your DNS is set up properly.
sudo changeip -checkhostname
Also... Have you bound the clients to the server? You have to do this in the System Preferences under Accounts in 10.6 and higher.
It's in the Directory Utility in 10.5
Once the client computers are bound to the server, you can start creating your User list in Workgroup Manager.
Unfortunately, there isn't a super easy way to automate this. You have to set up your groups, set up your group preferences (if you want any), add your users, and apply them to the groups.
There are some tricks to making this easy, ie set up a user template... That way all you have to do is type the user names and passwords (if you want them).
So here is the issue now. I didn't change anything yet because I wanted to see if there was a way to fix everything without having to recreate the directory. I see where the problems are on the server, but I have a problem connecting them all. DNS is working. The only errors I see are with Kerberos. I can connect to the server from the finder on any desktop, but if someone tries to log in, it says that the user is unable to log in at this time. The automount for the share point is 127.0.0.1, but the home directories are located at a different address. I'm not sure if this makes sense, but if it does, thanks so much for the help!
There's a great tutorial at
You may read it and find that there's a pretty simple fix, or you may decide that it's best to start over.
