setup question : mschap + perl authentication

[Johan <johan.arens@gmail.com>]

Hi community

I have a question for you guys. 

I'm wondering if it's possible to authenticate a user who is using mschap authentication with perl. 

I already made a perl script, which I use with rlm_perl to authenticate users to an ftp backend. I use that script to authenticate users from the authentication proxy of a Cisco PIX. 

My next setup is to authenticate user requests from a Wireless Access Point with EAP-TTLS. 
Is it possible to do that with the radiusd.conf ? 

I already tried to setup like this in the authenticate section : 

mschap {
  perl
}

But problem is, the perl script doens't seems to receive the same information as a PIX request. Do I need to modify my script to talk mschap ? 

Is there a perl module to understand the mschap protocol ?

Thanks in advance, 

Johan
