loadparm.c:

    With apologies to Charlton Heston and Pierre Boule.

    "You damn fools, you finally did it".

    Changed default security mode to be security=user.
    Yes this is a big (although small in code) change.
    It's something we've been discussing for a while, to
    finally wean people off the legacy security=share mode
    which is *never* what you want.

    Jeremy.

nmbd_incomingrequests.c: Bug fix for nmbd core dumps caused by overrun.
                         Found by <samuel@public.szonline.net>.
nttrans.c: More NT smb stuff.
reply.c: Unlink will overwrite an existing file. Well you learn
         something new about POSIX every day. :-).
server.c: Tidyup unreadable code.
smbpasswd.c: Code to allow -U remote_username to allow ordinary
             users to change remote passwords if their NT username
             is different from their UNIX username.
             Patch from <torbjorn.lindh@allgon.se>.

Jeremy.
