dont do that. leave authentication alone and use authorization

so, use  simple LDAP check to verify if someone can connect - this scales because you match
the SSID to the LDAP , configure the LDAP module so it can query your LDAP (which is AD)
for the users group and then

if ( ldap_stuff_here != &Called-Station-SSID) {

LDAP stuff can either be an LDAP-Group call or a %{ldap:} call. basically, get value from LDAP
and check against that supplied in the RADIUS request
