Have to give this a pass for now. I tried 8.3.0 an installed the web client. In that version it said Windows Auth is enabled. However when we try to log in, the wheel spins forever (both AD and admin account). In the IIS logfiles I only see a bunch of SignalR connection requests, and in the console there is a bit of debug info, like 'I am a zombie' type of useful info. This also happens when I try to log in on remote desktop. Anyways, we can't have our jobs disappearing every now and then, so we have to roll back to 8.2.5. Will try again in a future version. You may close this.
