It seems that not only wpa_supplicant but also hostapd is having
problems on -current systems: I just upgraded my access point from
netbsd-4 to HEAD (4.99.52 kernel, 4.99.50 userland, latest hostapd
including todays fixes by Joerg) and noticed other systems are also
having problems authenticating. This is what syslogd logged (with the
station's address replaced by its operating system name):
