My apologies if I'm out to lunch on this.

I inquired yesterday about connecting as a client to an NT 4 server with
ppp.  I couldn't get either pppd or iijppp to successfully authenticate.
I believe that this is due to the Microsoft Chap extensions on the NT
server which encrypts the username/password.  Anyways, I have turned off
those extensions on the server and expect everything to work fine but in
the course of exploring this I discovered some patches to pppd to support
the MS extensions.

These are at
ftp://sunsite.unc.edu/pub/Linux/system/network/serial/ppp/ppp-2.2.0f.tar.gz.
There is a README.mschap80 in this distribution and it includes patches to
make pppd use the MS extensions.  I took a quick glance in -current and
didn't see any indication that these patches have been applied.

I don't expect to need them and don't have the experience to pursue this
any further but I thought I'd send this in case anybody else has a need
for this information.

-Steve
