We had problems with AD after installing content version 729 this morning. Users were authenticated, but the logon process (group policy, drive mapping) was painfully slow. After we reverted to version 727 everything was OK again. The strange thing is that I see no traffic to our AD controllers being stopped by the firewall.
Anybody else seen this? We're using two PA-5050 in HA (active/passive) running PAN-OS 7.1.10.
