The driver itself is not actually associating with the access point, so
you never even get to the LEAP part.  You could try a few things:

1) just try to associate manually with 'iwconfig'.  Obviously you need
wpa_supplicant to do the LEAP stuff, but since you have to associate
first before you can start the LEAP exchanges, the driver should be
sending the associate event.  But it's not; and therefore wpa_supplicant
isn't able to start the LEAP exchange.  So anyway, run 'iwevent' in one
window, and do your iwconfig stuff in another, and see if you get an
SIWAP event that's not 0s.

2) Enable debug information in the ipw3945 driver, and get a dump of
what the _driver_ thinks its doing.  This is clearly a misconfiguration
problem between the driver and wpa_supplicant, but your config seems to
be the standard LEAP config, I -think-.

3) what happens if you take 'proto=WPA' out completely?
