We have a Zonedirector that's broadcasting 2 SSID, one for guests and one for internals that has Web Authentication configured with our AD.
We've had several users complaining that they lose connection and have to re-login to the portal. In the log we see the following entry when it's happening:
2014/02/13 13:40:45 Low User[user1] fails to join WLAN[Internal] from AP[ap01]
2014/02/13 13:49:27 Low AP[ap1] radio [11g/n] detects User user1 in WLAN[Internal] roams from AP[ap1]
2014/02/13 13:49:27 Low AP[ap1] radio [11a/n] detects User user1 in WLAN[Internal] roams out to AP[ap01]
2014/02/13 13:40:45 Low User[user1] of WLAN[Internal] is authorized at AP[ap01]
It looks like it's roaming between the radios and then fails to join. Is there any way to find out why it's failing?
