hi,
I am using free Radius 2.0. I want to try to authenticate with the perl
module, I've done all the necessary configurations in sites-enabled/default
directory and in radiusd.conf and it reads my perl script when running my
radius, unfortunately my radius server rejects all the time no matter what
i've put the return value rlm_module_ok in my perl script. Please tell me is
there any other things what i've to do to authenticate the username from
perl module.
Here is the output after running the radius server in debugging mode
