PEAPv1 testing

Hi all,

I'm trying to test several EAP methods, including PEAPv0 & PEAPv1. PEAPv0 works fine, but PEAPv1.
All other methods (e.g. EAP-TTLS, EAP-AKA, etc) work Ok.
I've done some Google search but I couldn't find any pointers.

I'm using eapol_test (v2.1) to test EAP methods.

This is my .conf file:

network={
        ssid="test"
        key_mgmt=WPA-EAP
        eap=PEAP
        identity="user"
        password="password"
        anonymous_identity="not anonymous"
        ca_cert="ca.pem"
        phase1="peaplabel=1"
        phase2="auth=MD5"
}

And this is eapol_test output:

Any pointers/examples/etc will be greatly appreciated.

Thanks in advance.
