It actually worked correctly in that case.  Most Windows applications
I've dealt with don't overwite existing files when saving.  They
create a new file, fill it with the information, delete the old file,
and rename new_name to old_name.

When Windows asks for the file, Samba does the right thing by sending
the link's target.  When Windows wants the file deleted, Samba
deletes the link instead of the target because that's the way links
are treated in *nix.  It has no way of knowing that Windows is really
doing a save operation.

I imagine the only way to deal with this would be making Samba cache
the file operations without doing anything destructive.  After X
time, review the cache for hints that a save was being done and then
perform the operation "properly".  That would probably require a
major rewrite and put a heavy load on the system.

Of course I could be wrong, I'm certainly not a Samba guru.  :)
