? How to disable CHAP on Windows95?

This is not quite a Livingston Portmaster problem, but I have a feeling
that
a) there are people on this list who may be running into this same
problem with RADIUS/CHAP/Win95, and (perhaps most importantly)
b) there are people on this list who know the answer... ;^)

The question: How do you (or can you) disable CHAP link authentication
in the Win95 PPP dialer?

Apparently, the Win95 PPP stack/dialler wants to attempt link
authentication in the following order:
1. CHAP, if that's not there, then:
2. PAP, if that's not there, then:
3. interactive login (chat script).

Our access servers will accept either PAP or CHAP from clients,
however, there is a flaw in the CHAP authentication portion of radiusd,
if you are using a DEFAULT user with a password of "UNIX". I.e. the
CHAP md5 comparisons will fail. (Won't go into detail here -- that's
not what I'm looking for...)

Anyway: we'd like to be able to tell Win95 to forget about trying CHAP
and just use PAP. That way, our DEFAULT password = "UNIX" logic in the
radiusd code will work fine.

So, in summary: is it possible to edit the registry entry to make the
Win95 PPP forget about CHAP?

Thanks in advance
