[pptp-server] pptpd+chapms+radius

I am trying to implement a VPN based on Linux PPTP server.
The clients connecting to this server are mostly W9x/NT/2k
The server should authenticate the tunnels (users) via a Radius server.


I have patched my ppp-2.3.11 with the following patches:

chapms-domain-strip
rh62-kill_fasync.patch
openssl-0.9.5-mppe.patch
and ppp-2.3.11.radius.pat  from http://www.ednet.ns.ca/~macleajb
(in crap-chap.tgz)

(system is kernel 2.2.14-15 stock RH6.2 distrib except for pppd 
and pptpd 1.1.1 compiled by myself)

I also added the appropriate line in /etc/ppp/chap-secrets

# client        server		secret                  IP addresses
*               *               !nothing          *

the problem is that the chap-crap-patched  pppd does not send
the right password to the radius server.

I can see that the radiusclient tries to authenticate users to the
radius server,
but instead it passes '!nothing' as the password string.

from /var/log/radius.log
Fri May 26 15:24:45 2000: Auth: Login incorrect: [jambo/!nothing] (from
nas eris/S0)




has anyone succesfully installed all the above and does this work?


I appreciate if anyone can help me.
