Cause
Kerberos login is configured incorrectly. Possible reasons follow:
• The Kerberos realm that the client PC is logged in to does not match the Kerberos realm
for which iLO is configured.
• The key in the Kerberos keytab stored in iLO does not match the Active Directory key.
• iLO is configured for an incorrect the KDC server address.
• The date and time do not match between the client PC, the KDC server, and iLO. Set the
date and time on these systems to the same value. The date and time on these systems
must not differ by more than 5 minutes.
Action
Verify that your environment meets the requirements for Kerberos support. For more information,
see “Kerberos authentication with iLO” (page 278).
Solution 3
Cause
There is a problem with the directory user account:
• The iLO computer account does not exist in Active Directory, or the account is disabled.
• The user logged in to the client PC is not a member of a universal or global directory group
authorized to access iLO.
Action
Verify that the user account exists and that it is a member of a group that is authorized to access
iLO.

support.
Action
Repair the DNS server.
