Hi, am trying to implement a WPA2 authentication system where users will be matched against the three criteria - user name - password - MAC address am using freeradius 1.0.1 with openldap 2.2.13 at its backend on CentOS 4.4 after extensively searching on google and freeradius-users mailing lists am able to do username/password authentication successfully using PEAP but am unable to get MAC authentication working and have run out of my wits myself had followed the tutorial on http://vuksan.com/linux/dot1x/802-1x-LDAP.html which worked great but am stuck on MAC address authentication. its repeatedly mentioned on mailling lists that MAC authentication is possible but i cant figure out how to do so hoping for some help thanks -- Registerd Linux User #426561 - Shobhit Jindal B.Tech.
