freeradius + pptp + mysql

[Michael Gale]

Hello,

	I am trying to get freeradius to work with my pptp / ppp server.

I have followed the documents from the following locations:
http://poptop.sourceforge.net/dox/radius_mysql.html
http://www.frontios.com/freeradius.html

However I am unable to get it to work when using freeradius.

pptpd-1.3.0-0
ppp-2.4.3-5.rhel4
freeradius-1.0.1-3.RHEL4.3

My client is a XP Pro laptop using MS-CHAP v2 I believe, with just pptp 
/ ppp and using a chap-secrect file it work great.

However once I introduce freerdius and mysql I am unable to authentication.

The following works fine on my test server:
radtest testuser testpass localhost 1812 testing123

When trying from the XP Pro client it fails with:
rlm_mschap: No MS-CHAP-Challenge in the request

I have added the logs below, any feedback would be appreciated.

Here are the logs:
