problem continues in hostap/hostapd/wpa_supplicant - new development release, v0.4.5

I continue to have problems with wpa_supplicant and ndiswrapper when I 
am trying merely to associate with auth_alg=SHARED and WEP keys.   For 
some reason, the EAPOL state machine still wants to force 
authentication, so after associating and connecting, a timeout happens, 
and wpa_supplicant forces a disconnection.   See script below, which is 
generated, where the relevant wpa_supplicant.conf says:

network={
        ssid="Reed.com"
        key_mgmt=NONE
        auth_alg=SHARED
        wep_key0=...
        wep_key1=...
        wep_key2=...
        wep_tx_keyidx=0
        priority=5
}

I have marked the point in the transcript where connection succeeds, and 
then after a pause of many seconds, the connection is killed.

What's suspicious is the "portControl=ForceAuthorized" line after 
SCANNING->ASSOCIATING.   I can't figure out why wpa_supplicant.c does 
this, but I'm no WPA expert.

I used to love WAPROAMD, it worked for this case just fine.
