We have an 4402 controller running 4.0.206 and a 4.1.1 ACS appliance. In the controller we are using some WLANS with MAC authentication (that works fine) and one WLAN that should be using Web Authentication. Here is the problem:
If i configure the user/pass in the ACS, and then try to connect to the WebAuth SSID, the user never gets IP and never sees the authentication page..
IF I also configure the mac-address of that particular machine, then the user gets IP and then sees the authentication page, enter the user/password and the thing works fine.
Obviously, there is no need to enter the mac-address of the user if we are just using the web authentication, but for some reason it is only working if we enter the mac-address also.
Also, in the "passed authentication" log of the ACS, we see the user/password attempt working, but in the "logged in users" we se the user as the mac-address.
I disabled HTTPS and enables HTTP, and now it works, but the "logged in users" log in the ACS is not working now. The RADIUS accounting account is working, i see the start-stop messages, but the "logged in users" always show 0 users.
