UNAB Registration Failed Due to Incorrect Clock Skew

Symptom:

When I try to register UNAB with Active Directory, I receive the following error message:

Clock skew too great while getting initial credentials Kerberos preauthentication using <Administrator> failed

Solution:

UNAB registration failed because the clock skew between Active Directory and the UNAB endpoint is larger than configured.

To resolve this issue, do the following:

1. Manually synchronize the UNAB endpoint clock with that of Active Directory.
2. Set use_time_sync token value to yes under the [Agent] section in uxauth.ini to automatically configure time synchronization.
