I am also experiencing this issue with our captive portal setup using v. 6.1.1.0 and integrated with clearpass guest self registration. My experience has been the captive portal is displayed correctly (hosted on clearpass server) for a period of time, but eventually the redirects start to happen (IE just times out, other browsers show "too many redirect" messages). This is also user specific, so a brand new user can authenticate just fine, but someone who has been using the guest network all day will most likely see this mid afternoon when trying to reconnect.
There doesn't seem to be any errors on the clearpass but the error on the controller that I see right around the time this happens is
error 522043: Configured Session limit reached for client IP=[my IP address].
Not sure if this is something being sent from clearpass to the controller or if it a configuration present in the controller itself that is causing this error. More over I don;t know what the session limit is even set to, where to find it, etc. The recomended action in the syslog reference guide is to turn the client off until sessions have been cleared but would be nice to resolve a different way.
I confirmed the wired AAA profile is set to default as suggested in a previous post. I also have a case open with TAC, #1314697. The tech's have pcaps and controller logs.
Has anyone had the same experience with the same logs in the controller and the too many redirects/timeout? Any progress on this issue from the other guys that posted originally?
