path... after we've talked to any RADIUS servers involved, so that we haven't touched the data before it gets to the server. Make it clearer in the code that this compensation is done by setting a flag to a value of zero, a flag which rfc2759 says *MUST* be zero. While we're here, don't bother passing the peer challenge into radius_Authenticate(). It's already part of the key we're passing in (this becomes obvious now that I've structured that data...). This ``fix'' doesn't help to authenticate Win98/WinME users in my test environment as ports/net/freeradius seems to ignore the flag completely anyway, but it may help with other RADIUS servers.
