Am using ISE 1.2 to authenticate guest users on the WLC.
I created a sponsor account that creates guest credentials (username and password) and a time profile of 8hours, 24hours, 1week, 1month and 3months repectively and it worked fine.
Recently, it accepts the guest credentials and gives access to the network for about 2 to 3 minutes before it terminates the session and asks the user to re-authentication on the guest portal. This continues repeatedly irrespective of the time profile i choose. Moreover, every other users aside from the Guest users authenticate on the ISE without such challenge.
Thanks for ur suggestions in advance.
