Description (partial)

When using 802.1x one can select "Use AES Key Wrap" under the Radius Authentication settings, however WLC rejects the authentications with "Rejecting Cisco MAC Attribute due to MAC mismatch" as soon it receives a Radius Access-Challenge from the Radius Server.
In MessageLogs we see:
 #DOT1X-3-ABORT_AUTH: 1x_bauth_sm.c:449  Authentication Aborted for client xx:xx:xx:xx:xx:xx
 #DOT1X-3-INVALID_KEYWRAP_PKT: 1x_auth_pae.c:3163 Received invalid keywrap packet - invalid interim response

WLAN with WPA2-Enterprise and AES. Enable "Use AES Key Wrap".
