I have two 5508 WLCs which where running 7.0.x and to test out features on ISE, I upgraded that to 7.3.x, Since then I am facing issue on concurrent users.
I have mulitple ssids having dot1x and webauth security. WebAuth is taking local user database and dot1x is using my AD through ISE as Radius server.
Before I upgrade my WLC, the setting was to allow single user session on SSID having WebAuth security and unlimited for dot1x
Max Concurrent Logins for a user name was set to 1.
After I upgrade it to 7.3, settings remains the same, but the single session limit is now applicable to all my SSIDs, For every SSID a user will be allowed only from a single device. I tried changing the Max-Login Ignore Identity Response to enable/Disable state. But no luck on that one.
Then I decided to degrade the WLC to 7.2, but still the same issue.
