Silly mapping bug?  NTSTATUS -> dos stuff?

As to smbmount, would you like the 'negotiate' patches put into Samba
HEAD?  I'm *very* interested in the kerberos stuff, particularly with
Samba unix extenstions.

Possibly becouse Samba client code is *ugly* :-).

The idea there is just like smbmount - the syntax comes from a desire to
be a bit like NT, and an attempt to get just one client utility -
instead of a small gaggle of little, undocumented utilities.

I look forward to lots of breakage/deveopment in both implementations -
its good to see there is still some life it this area :-)
