Hostapd and Wpa_supplicant in WPA2 EAP-TLS mode?

hi

 I am trying to get the hostapd and WPA_supplicant to work with WPA2
authentication with EAP.
I have them running with 802.1x authentication with EAP-TLS.

 My wpa_supplicant configuration is


network={
	ssid="test"
        proto=RSN
	key_mgmt=WPA-EAP IEEE8021X
      	pairwise=CCMP TKIP
        group=CCMP TKIP WEP104
	eap=TLS
	identity="client at example.com"
        ca_cert="/etc/certs/CRYPTO.pem"
	client_cert="/etc/certs/clientCA-cert.pem"
        private_key="/etc/certs/clientCA-key.pem"
        private_key_passwd="secretpassword"
	eapol_flags=3
        priority=1

}


And the hostapd configuration:

interface=wlan0
logger_syslog=-1
logger_syslog_level=-1
logger_stdout=-1
logger_stdout_level=-1
debug=2
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=test
macaddr_acl=0
accept_mac_file=/etc/hostapd.accept
deny_mac_file=/etc/hostapd.deny
ieee8021x=1
own_ip_addr=198.134.129.104
nas_identifier=client.example.com

# RADIUS authentication server
auth_server_addr=198.134.129.204
auth_server_port=1812
auth_server_shared_secret=secret

# RADIUS accounting server
acct_server_addr=198.134.129.204
acct_server_port=1813
acct_server_shared_secret=secret

wpa=1

wpa_key_mgmt=WPA-EAP

wpa_pairwise=TKIP CCMP

wpa_group_rekey=300

wpa_gmk_rekey=6400

>From the readme files and some other mails in the list I gather this is
the correct configuration for WPA2 with EAP-TLS.

 The access point gets the association request from the supplicant but
does not respond as it does not detect it to be WPA/RSN capable.

The hostapd log:

Could someone point to me what is going wrong with the authentication. And
why the supplicant does not include RSN capability in its association
request.


Thanks
