WPA2 Enterprise with EAP-TLS auth issue with freeradius2 1.7.3_1



  • I manage to set up WPA2 Enterprise with EAP-TLS.

    After some security testing I can see that I can login with correct generated certificate but with NO user at all in “FreeRADIUS > Users”
    and I have
    “Check Client Certificate CN” enabled in Package/FreeRADIUS: EAP/EAP /EAP-TLS

    I’m  running:
    2.3.1-RELEASE-p1 (amd64) built on Wed May 25 14:53:06 CDT 2016 FreeBSD 10.3-RELEASE-p3
    with freeradius2 1.7.3_1.

    The guide I was using is from https://doc.pfsense.org/index.php/Using_EAP_and_PEAP_with_FreeRADIUS

    I’m missing something or its is a known bug?



  • Hi,

    found this on the web:

    No, the only thing that check_cert_cn does is make sure that the CN in
    the certificate matches the User-Name attribute in the RADIUS request.
    It's basically just a sanity/security check on the request itself.  It
    does not go looking on other autz sources for you.  It is up to you to
    decide elsewhere (users file, SQL DB, LDAP) whether or not to allow that
    user to authenticate.  If you do nothing, the user will be allowed to
    authenticate by default.  If, for some reason, you decide you don't want
    a user to be allowed to authenticate, you must specifically reject him.

    So if you want to block a certificate you need a CRL (Certificate Revocation List) and put the certificate in it.
