vCenter / Active Directory user group sync

VCSA 6.7 U3

Hi. I have the VCSA joined to AD via Integrated Windows Authentication. Synchronization of group membership from Active Directory to the VCSA is very slow - approx. 50 minutes.

For example, I add a user to the 'Full Admin' AD group. It will take approximately 50 minutes for AD/VCSA to sync and grant the full admin permissions on user login.

NTP is configured for the ESXi hosts / Domain Controllers / VCSA and I've verified all are consistent.

Is there a value somewhere set for the AD/VCSA sync?

Is there a way I can force the sync ?

Thanks in advance.
