Hi all experts.
I recently have experienced this issue.
I have been using ISE184.108.40.206 and joined to AD since the ISE was released, but never seen this error before.
I did not touch any configuration and I was trying to test CWA with multiple WLCs.
I finished all configuration about CWA, and I was verifing if it is working.
while I was trying to login as user on AD, I could not. so I looked up on External Identity Source and it apears.
does anyone know why it is giving me that error ?
the ISE and AD both see the same NTP and time difference between them is only 1 minute, timezone is same.
even though they are looking at the same NTP, it's outside of private network and it is isolated.
also, I am able to ping each other. DNS is working. I don't see why it is not working......
can anyone help me with this problem ?
