Starting today I was getting intermittent authentication failures in ISE. It would say that the user was not found in the selected identity store. The account is there though. At one point I ran a authetication test from the external identity source menu and I got a failure and then the next time a pass. I have no idea why this is happening. I just updated to ISE 1.2 the other day. I'm also seeing what looks like a high level of latency on both of my PSN's. Is this normal? Any ideas?
