"For I have laboured mightily on Luke's code, and hath broken

all I saw" - the book of Jeremy, chapter 1 :-).

So here is the mega-merge of the NTDOM branch server code.
It doesn't include the new client side pieces, we'll look
at that later.

This should give the same functionality, server wise, as
the NTDOM branch does, only merged into the main branch.

Any fixes to domain controler functionality should be
added to the main branch, not the NTDOM branch.

This code compiles without warnings on gcc2.8, but will
need further testing before we are sure all the working
functionality of the NTDOM server branch has been
correctly carried over.

I hereby declare the server side of the NTDOM branch
dead (and all who sail in her :-).

Jeremy.
