8. Troubleshooting
• The KDC and machine timing do not match.
Authentication will fail if the difference between the KDC and machine timing is more than 5
minutes. Make sure the timing matches.
• Kerberos authentication will fail if the realm name is specified in lower-case letters. Make sure the
realm name is specified in capital letters.
• Kerberos authentication will fail if automatic retrieval for KDC fails.
Ask your service representative to make sure the KDC retrieval settings are set to "automatic
retrieval".
If automatic retrieval is not functioning properly, switch to manual retrieval.

Authentication timed out because the server did not respond.
• Check the network configuration, or settings on the authenticating server.

The authentication server login name is the same as a user name already registered on the machine.
(Names are distinguished by the unique attribute specified in LDAP authentication settings.)
• Delete the old, duplicated name or change the login name.
• If the authentication server has just been changed, delete the old name on the server.
