We are seeing these messages in our CAM logs:
"Unable to add user to Clean Access Server <CAS IP>, [00:00:00:00:AA:13 ## x.x.x.x] username"
While the clients see:
"Invalid Clean Access Server"
We are running 220.127.116.11 software and using In-Band for our wireless. This is best reproduced by logging into CA via the agent and then move locations (wireless). At the new location the agent says "logged-in" but when you open a web browser you are redirected to the web authentication page. When you login to the web auth page you'll fail and receive the "Invalid Clean Access Server" error message below the login form. After this you are in a loop you can't get out of even after right-clicking the agent and logging off.
The problem started after our upgrade from 4.1.1 to 18.104.22.168. Our TAC engineer hasn't found a solution yet so I thought I'd post here. Any help would be greatly appreciated.
