ISE - Active Directory 2012 NTP Synchronization Error

Hello,

We are having a problem with ISE-AD NTP Synchronization. Found similar threads about NTP Synchronization, but although ISE-AD Ntp sync is recommended, it seems that some compatibility problems may occur. Instead as a workaround synching with other Catalyst Swithes running as Ntp servers or synching with external ntp servers or using another NTP solution is recommended.

Is there a recommendation on how to troubleshoot or configure NTP synchronization between ISE 1.3 and Active Directory 2012 Server? Is it possible to be some parameter such as NTP version? If switches or routers can synchronize, then ISE should be synchronized without using another ntp source in order synchronization of logs etc.

Thanks in Advance,

Best Regards,
