We have a 2100 Wlan controller set up with multiple wlans.
We are having problems on the Guest VLAN in that everytime a user tries to authenticate via Web Auth, they fail and are redirected to the username/password page.
Local accounts have been added and the WLAN has been set up to use web auth but each time a user tries to authenticate the following message is in the log:-
NOV 21 09:47:21.852 pem_api.c:4513 PEM-1-WEBAUTHFAIL : Web Authentication Failure for station aa:bb:cc:dd:ee:ff
If the box is rebooted it works for around an hour, then begins to fail again.
Any ideas?
