Yep that is what I am seeing between poptop and the client.

What password?  My radius server has has access only to the
username/password pairs used to log in to the radius server itself.

I was afraid of that.  It looks like radius and MS-CHAP are closely
tied together in poptop; where poptop really means pptpd + mppe + pppd.

That is what I thought.

This leads to another question.  Can I use something other than
MS-CHAP.  My unalterable constraint is that I must use my
radius server which uses username/password for authentication.
