I have Snow Leopard Server (10.6.8) running on a Mac Mini for the past 3 years. The client Macs were all running Snow Leopard and could happily do network logins. I recently upgraded my client Macs to 10.7 and 10.8.Now they cannot login via Network logins. Only via the Other selection. Network logins produces the Error occured dialog box. Once users do a local login, they have access to all server services (file sharing, calendar, messaging, contacts, etc.)
The server is setup as a OD Master with Kerberos. The changeip check is all good. The DNS is working. I have made no changes to the server. Only the clients were upgraded from Snow Leopard.
I have read a lot about similar problems but still haven't solved this problem.
I hope someone can help.
