[Samba] smbpasswd -r connecting to old samba not working

The only problem with that is the old servers are NOT our servers --
they are not managed by us.  It's hard for us to tell people 'hey, we
updated something, so now you have to'.  Regardless of if it is a bug
with the old version of samba, I would imagine there is some value in
being backwards compatible with old versions, regardless of being
maintained.  The crux of the whole deal is that in the world of password
changing, the old smbpassword worked against everything, now in order to
get support for the new 2003 server boxes that need samba 3 to connect
to them, we lose support for changing passwords on a large set of other
boxes.  The obvious answer to this from an operational stand point is to
use the old binary / install base for changing passwords on these boxes,
but I was hoping that there was some simple fix / work around that would
address the backwards compatibility issue I have ran into.  It seems
somewhat strange that we would strive for backwards compatibility for
old servers using protocols like CORE, COREPLUS, LANMAN1, LANMAN2 etc..
but not support older samba releases IMHO.
