This is the part that is the mystery.  There seems to be scarce
information out there about how pppd functions when using radius as a
back end (apart from it should 'just work') - most of the documentation
about pppd relates to dial-up as a ppp client or a server without using

I thought this list was exactly the sort of place that people who may
have come across a similar issue could be found.  Sorry for the noise if
