 Hi,all. I want to use hostap for WPA EAP-TLS. Here is my .conf file:
interface=wlan3
bridge=br0
driver=nl80211
ssid=NormalAP
hw_mode=g
channel=13
ieee8021x=1
eapol_version=1
eap_server=1
eap_user_file=/home/wlan/wlan/hostapd-wpa-tls-tkip/hostapd/hostapd-ap.eap_user
ca_cert=/etc/ssl/demoCA/newcerts/cacert.pem
server_cert=/etc/ssl/demoCA/newcerts/APcert.pem
private_key=/etc/ssl/demoCA/newcerts/serverkey.prv
private_key_passwd=wlanwlan
#dh_file=/etc/ssl/hostapd.dh.pem
wpa=1
wpa_key_mgmt=WPA-EAP
wpa_pairwise=TKIP

But the hostap can not derive the key, here is the error message:
 EAP-TLS: CONTINUE -> SUCCESS
EAP: EAP entering state SEND_REQUEST

I use similiar conf file for the WPA2 EAP-TLS, it is OK. Where is problem? Thank you!
