Dear Friend

 

When I use VPN with PPTP authentication, it works perfectly, but when  I try
to authenticate by using PPTP against a radius server, I got some errors !

Apr 15 09:25:19 mpd: Not expected, but that's OK

 

 

The Radius Server is running FreeBSD + FreeRadius + MySQL to authentication
and accounting, is possible to authenticate by using PPPOE clients without
problems, however the PPTP clients cannot.

 

I believe the problem is something related to MS-CHAP, The FreeRadius
configuration already have a session for MS-CHAP authentication, but still
don't work.

 

Any suggestion, please ?
