Message-Authenticator

[Manuel Sánchez Cuenca]

Hello all, I have installed hostapd-0.1.3 as Access Point, FreeRadius 
0.7.1 as Authentication Server, and Xsupplicant 0.8 as client. But when 
I try to connect to the system whit the client, FreeRadius show "Sending 
Accexx-Accept", but Hostapd show:
   
    wlan0: STA 00:40:05:ae:d7:70 IEEE 802.11: authenticated
    wlan0: STA 00:40:05:ae:d7:70 IEEE 802.11: associated (aid 1)
    No Message-Authenticator attribute found
    Incoming RADIUS packet did not have correct Message-Authenticator - 
dropped
    No RADIUS RX handler found (type=0 code=2 id=1) - dropping packet

know anybody what is the problem?

Thanks in advance.
