No AD authentication after upgrading to BigIP-V12HF1

Thanks for the answer. I did a capture and sent it to support, have not yet heard back. I can look at the management port on the one that is online (this is a HA pair):

root@(dc2-bigip-test)(cfg-sync Disconnected)(Active)(/Common)(tmos) list /sys management-ip sys management-ip 10.10.29.60/24 { description configured-statically

And this is the management port of the one that is offline (that we are working on).

root@(dc1-bigip-test)(cfg-sync Disconnected)(ForcedOffline)(/Common)(tmos) list /sys management-ip sys management-ip 10.10.29.59/24 { description configured-statically }

So, they at least exist! Looking at the pcap file I generated/sent, I can at least see LDAP communication between our BigIP and the domain controller (for our AD) that says, "success".
