Kerberos authentication failed.
• Kerberos authentication settings are not correctly configured.
Make sure the realm name, KDC (Key Distribution Center) name, and corresponding domain name
are specified correctly.
• 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 upper-case 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.

• If the authentication server has just been changed, delete the old name on the server.
