Caveats

CSCsu95035—EAP-FAST profile might disappear after login when you use the .dat file to install
ADU. This occurs when one user (user A) changes one or more profiles or adds profiles, and a
second user logs (user B) onto that same station. This only occurs if the .dat file that is created by
ACAU is configured with the overwrite option.
ADU. This occurs when one user (user A) changes one or more profiles or adds profiles, and a
second user logs (user B) onto that same station. This only occurs if the .dat file that is created by
ACAU is configured with the overwrite option.
Workaround: User that is configuring the profiles (user A) should not use the overwrite option.
Another workaround is to export the profiles before another user (user B) logs on to the same station
and then reimport the profiles after user B logs on. This process must be followed for all subsequent
users that log onto that same station.

CSCsj10654—Client MFP failed with 802.11h frame spoofing
After the controller is configured to use a RADAR-detecting channel, a client is associated with
WPA version 2 AES-CCMP with 802.1X. On an 802.11h access point, a RADAR-detection event is
triggered. A valid 802.11h channel change frame is captured with a sniffer. The access point has
client MFP enabled from the controller.

triggered. A valid 802.11h channel change frame is captured with a sniffer. The access point has
client MFP enabled from the controller.
When the channel change frame is replayed to the client, the ADU disconnects the client adapter.
The client adapter then reassociates with the controller access point.
