Sometimes it is impossible to connect to an AP. It just looks like that he pairwise key handshake fails. This is what i see in the log:

Feb 28 20:13:41 10.0.0.3 hostapd: wlan1: STA 00:13:ef:60:0a:3a IEEE 802.11: authenticated

My config for wpa2-eap is pretty simple:

config wifi-iface 'default_radio1'
        option device 'radio1'
        option mode 'ap'
        option ssid 'SSID'
        option encryption 'wpa2'
        option auth_server '10.0.0.1'
        option auth_port '1812'
        option auth_secret 'foobar'
        option nasid 'ap02g'
        option network 'lan'
        option wpa_group_rekey '2000'
