[Samba] Default Posix ACLs are ignored when copying files between
two directories using Windows (XP)

I'm seeing this exact same behavior on my Samba server. For what it's
worth, I also see this same behavior with shares/folders on a Windows NT
system. It seems Samba/Linux and Windows NT behave the same in this regard.
One thing you can do is tell your users to "copy" files from directory A to
directory B, then delete the original files from directory A. It's
annoyingly inconvenient, (and inefficient) but it works.
I've taken to running the following command from my Samba server whenever my
users "move" files between directories with different ACLs,
getfacl . | setfacl -R --set-file=- *
Another thing you can do is put directory A and directory B on different
filesystems. This will cause ext3 (or whatever) to actually create new
inodes for each file and set the permissions appropriately. (This isn't an
option in my environment, but might be for you.)
Let me know if you find a more elegant solution!
