I have a Sophos XG 105 and just enabled AD Sync and STAS for transparent authentication. Everything works at first and then, boom, the connections gets dropped and users lose internet; they disappear from the "Live Users" window on STAS.
I've checked over my configurations multiple times, called tech support, everything is configured as it should be. Has anyone had experience with this and what has the fix been? I'm running STAS on a Server 2012 R2 DC, it passes all the testing, etc. In order for users to reconnect they have to lock the PC and then log in again and they get internet back.
