How to configure FreeBSD as WPA Enterpise access point?

I have a FreeBSD machine with an Atheros WiFi card and I want to use it as WPA Enterprise access point. I set up a RADIUS server on the FreeBSD machine and configure interface wlan0 and hostapd.conf, but I have no luck. My phone informs me that the MyWiFi network is password protected and refuses to accept my certificate. But I successfully use an access point (a white box with antennas and blue LEDs) as a WPA Enterprise access point from my phone. So I suppose I set up the RADIUS server correctly.

wlan0: flags=8843 metric 0 mtu 1500
        options=0
        ether 00:1a:cc:44:33:aa
        inet 192.168.12.1 netmask 0xffffff00 broadcast 192.168.12.255
        groups: wlan
        ssid "MyFiWi" channel 1 (2412 MHz 11g) bssid 00:1a:cc:44:33:aa
        regdomain NONE country DE ecm authmode 802.1x privacy MIXED
        deftxkey UNDEF txpower 30 scanvalid 60 protmode CTS wme burst
        dtimperiod 1 -dfs
        parent interface: ath0
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11g 
        status: running
        nd6 options=29

My /etc/hostapd.conf:

# GLOBAL PARAMETERS
interface=wlan0
debug=0
logger_syslog=-1
logger_syslog_level=0
logger_stdout=-1
logger_stdout_level=0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel

ssid=MyFiWi

# WPA/IEEE 802.11i PARAMETERS

nas_identifier=FreeBSD
auth_server_addr=127.0.0.1

My /etc/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
#
# home network; allow all valid ciphers
 network={
        ssid="MyFiWi"
        key_mgmt=WPA-EAP
        eap=TLS
        ca_cert="/home/MyFiWi.pem"
 }

What I do wrong?
