Setting up WPA-PSK with madwifi

I was setting up my wireless AP to support WPA-PSK, for that I used the
following instructions:

http://madwifi.org/wiki/UserDocs/HostAP
http://madwifi.org/wiki/UserDocs/WPA_PSK_on_Both_Ends

Mainly under Debian you have to issue:

apt-get install hostapd

and modify /etc/hostapd/hostapd.conf following the instructions in
madwifi.org. But I kept getting among all the traces this:

madwifi_del_key: addr=00:0c:f1:5d:de:b5 key_idx=0
madwifi_set_sta_authorized: addr=00:0c:f1:5d:de:b5 authorized=0
ath0: STA 00:0c:f1:5d:de:b5 IEEE 802.1X: unauthorizing port

I just had to change in hostapd.conf

from eapol_version=2

to eapol_version=1

and now it works!! :-D

Hope this helps for those who had the same problem...
