[Samba] Leopard SMB File Move Permissions Bug ?

[ScottZ]

Yea, I realize this is an Apple problem since they do their own things
with Samba, but wanted to confer with the samba experts here as Apple
has yet to fix this in the last year (10.5.2 to 10.5.5). 

I've recently report it to apple as still a bug but wondering if it
might have a workaround?

Scenario:
You created or have an existing file on a mac smb share

Permissions look like:
-rwxr--r-- 1 Albert staff 2048 Sep 16 11:00 file.txt

If you move the file to another location on the smb share via an XP
client, permissions end up as:
---------- 1 Albert staff 2048 Sep 16 11:00 file.txt

Same thing for directories.
It doesn't matter if the files or directories exist prior to the move or
are newly created.
It also doesn't matter if the directory your moving the files/directory
to exists or newly created.

Mapping a drive on the xp client and using a command prompt, I can move
a file successfully with the move command and it retains it's original
permissions.

Version of Samba being reported in Leopard 10.5.5 is 3.0.25b-apple

No errors are showing up in nmbd or smbd logs when the file/directory
move is done.

Their default smb.conf is:
