Were you originating AD authentication from the management port before the upgrade?
I've seen cases on earlier versions where administrative traffic that was previously being originated from the management port, started using the service interfaces on the default route on the default routed domain %0 after the upgrade, instead of the default route on the management interface.
Have you done any packet captures to see the F5 attempts to connect to AD?
If you do the captures and validate that's the situation, you can use this article:
