Okay i think you are confused
For example this particular user got a mac caching for a few days so its authenticating via MAC address so the captive portal is not presented or anything.
And the user is getting that error :/
So there is no redirection or captive portal or anything!
The user did tell me that it start happening on a remote site which is another controller(local controller), and it start happening there.
He did registerd on the central site and eveything worked correctly
Right now the user is working fine, he turned the wifi on again and the message didnt appear on the central site.
If they get the problem again, ill try to connect to the controller and get more info... right now to be honest i dont have too much info as i have not troubleshoot it mysleft... I just find it odd because i have never seen that error pop in any of our client using clearpass guest....
Also thanks for your time in asnweringn me Herman!!! :)
Cheers
Carlos
