A very long time ago (actually 6 months ago) I promised to commit this code
to the Samba tree.

Originally written by Nigel Williams" <nigel@veritas.com>, I've been
trying to keep it in some form of shape for the last 6 months.  In particular
I think some of the code got committed a few months ago, and others have made
changes to the CVS version over time.

anyway, its finally in - and doesn't appear to have broken anything.

Now to try the client-side patches :-)
