wpa_supplicantがサービスとして起動すると、Centos 6 EAP認証は失敗します。

wpa_supplicantサービスから起動するとsudo service start wpa_supplicant（スタートアップファイルにあっても同じ問題が発生します）、ラップトップはEAPネットワークに接続できず、次のエラーが発生します/var/log/wpa_supplicant。

私に関連する部分は次のとおりです/etc/wpa_supplicant/wpa_supplicant.log。

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1

network={
    ssid="eduroam"
    proto=RSN
    key_mgmt=WPA-EAP
    pairwise=CCMP
    group=CCMP
    eap=TLS
    identity="[email protected]"
    ca_cert="/home/chris/cert/ca.crt"
    client_cert="/home/chris/cert/cert.pem"
    private_key="/home/chris/cert/key.pem"
    private_key_passwd="LONGPASSWORD"
    priority=10
}

そして私/etc/sysconfig/wpa_supplicant：

# Use the flag "-i" before each of your interfaces, like so:
#  INTERFACES="-ieth1 -iwlan0"
INTERFACES="-iwlan0"

# Use the flag "-D" before each driver, like so:
#  DRIVERS="-Dwext"
DRIVERS="-Dwext"

# Other arguments
#   -u   Enable the D-Bus interface (required for use with NetworkManager)
#   -f   Log to /var/log/wpa_supplicant.log
#   -P   Write pid file to /var/run/wpa_supplicant.pid 
#        required to return proper codes by init scripts (e.g. double "start" action)
#        -B to daemonize that has to be used together with -P is already in wpa_supplicant.init.d
#   -t   include timestamp in debug messages
OTHER_ARGS="-f /var/log/wpa_supplicant.log -P /var/run/wpa_supplicant.pid -t"

オープンネットワークはうまく機能し、wpa_supplicant手動で実行するとすべてのネットワークがsudo wpa_supplicant -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -B。

編集：いくつかの追加情報 - WPA2-PSKネットワークに正常にアクセスできたため、EAP-TLSに固有のようです。
