Hello all,
I am configuring freeradius with Cisco AP as access device and Microsoft AD as User database for users authentication by email and password but still having some bugs.
So if anyone have used familiar solution please kindly guide me config radiusd.conf file so FreeRadius can communicate with MS AD.
Yours Respectfully,
Tran Nam Thang.

Hello Peter and all,
Yes i managed to work authentication via rlm_perl. I can get accept or
reject without a problem.
WHat i wonder is can i use it as a hybrid system as, to keep radacct logs
in sql, or to get some info data from radgrouprelpy or smwhere?
Or some stuff similar like this.
I just wanna use rlm_perl for user/pass matching thats all. Rest should be
by mysql.
Or do i have to write all this modules manually in my perl script too?
