Potential Cause and Solution: Can indicate that principal name specified to be added to the key table does not exist in the Active Directory database. TLS Certificates If you are using TLS to authenticate or protect the LDAP traffic, then the Active Directory server must have an appropriate certificate. For example, problems may occur if a client computer knows an application server as appserver1.example.com, but the Kerberos server knows the same computer as appserver1. his comment is here
Solution: Start authentication debugging by invoking the telnet command with the toggle authdebug command and look at the debug messages for further clues. Is each computer in the environment within 5 minutes of all the others? Solution: Make sure that the messages are being sent across the network correctly. Solution: Make sure that the client is using a Kerberos V5 protocol that supports initial connection support. http://kb.mit.edu/confluence/pages/viewpage.action?pageId=4981263
Active Directory domain controllers, Windows clients, UNIX clients, and application servers must all have a shared understanding of the correct host names and IP addresses for each computer within the environment.
