AAA, NAC, Guest Access & BYOD

Environment : This applies to all versions of CPPM.

I see the below error when i join the server.

Adding host to AD domain...
INFO - Fetched REALM 'CLEARPASS.ARUBA.COM from domain FQDN
'clearpass.aruba.com'
INFO - Fetched the NETBIOS name 'CLEARPASS'
INFO - Creating domain directories for 'CLEARPASS'
Enter cppm-admin's password:
kerberos_kinit_password cppm-admin@CLEARPASS.ARUBA.COM failed:
Ticket is ineligible for postdating
Failed to join domain: failed to connect to AD: Ticket is ineligible
for postdating

ERROR - CPPM failed to join the domain CLEARPASS.ARUBA.COM
with domain controller as clearpass.aruba.com
Join domain failed

This issue us caused because of the time/time zone mismatch.

The above issue will be  resolved by making sure that the time is proper on the CPPM and AD server.
