style='font-size:12.0pt'>Hi,<br>
<br>
I need to develop a custom authentication module to handle OTP authentication
and integrate it to Freeradius server. <br>
<br>
My questions are : <br>
<br>
1- are files with rlm_ prefix PAM modules or simply authentication modules? <br>
2 - What should I write exactly other than an rlm_ file ? <br>
3- For a good beginning, what are the files that I should read first ?<br>
<br>
<br>
</span>thanks for your help.</font></p>
