Problem with WPA-PSK

[Ugo Campiglio]

Hi,
I sent a message on Friday about a PSK problem but I didnt receive any 
comment.
I send you more detail about my configuration. I made work hostapd 
during some tests a few months ago but now I lost my old config. I am 
using the last CVS tar.gz.
I remind you the problem : I am trying to use Hostapd as access point 
for XP clients. Xp detects a connection. With a sniffer I see that 
hostapd sends the first eapol key but XP does not answer correctly 
(sends an ACK and an EAPOL START instead of the EAPOL Key 2).
I suspect there is a problem in the beacon but I was not able to 
identify it. Here is my configuration file.
If somebody can help me I'd be grateful.
Thanks,
Ugo
