As I've also said repeatedly, the client sends the authentication
request to the server, and the server does not, and can not control
what authenticate type the client uses.

It probably comes from pppd or l2tpd. I recall that the
configuration you posted earlier disabled chap, so I don't know why
the client would still be using it.

If the RADIUS server is receiving a CHAP-Password in the request,
then something else in the system is using CHAP. You *think* you've
configured it to use MSCHAP, but that is obviously not happening.

The problem isn't understanding how it works. The problem is
believing things that are explained on the list.
