unable to configure WPA with madwifi

[Tiago Rodrigues]

Hi,

I have configured a linux box with a pci with the atheros chip to act
as an AP, bridging my wired net with the wireless net. Everything is
working ok with WEP.
Now I wanted to use WPA. I configured Hostap but I can't get it to
work. The clients keep trying to connect but the hostap is always
deauthenticating them (madwifi_sta_deauth: addr=XX:XX:XX:XX:XX:XX
reason_code=2). I can't find any info on the reason_code=2.

here my hostap configuration file and hostap output:

*** HOSTAP CONFIG FILE:
