I appear to be running TKIP so I changed the above settings, although
I have 'wpa_pairwise' on hostapd-0.5.10 instead of 'rsn_pairwise'.  I
also noticed I have 'wpa_key_mgmt=WPA-PSK' set.  I can't connect to
the AP in its new configuration.  Here is wpa_supplicant.conf on the
client:

network={
        ssid="networkname"
        key_mgmt=WPA-PSK
        psk="longrandompassword"
        proto=WPA2
        pairwise=CCMP
        group=CCMP
}

Am I configuring the client incorrectly, or could it be the server?
