[Samba] samba does not lock files

I doubt this has anything to do with Samba.  If you want to have proper
file locking you need to actually mount the CIFS filesystem;   otherwise
you are most likely opening and saving the file via GNOME-VFS
(ldd /usr/lib/ooo-2.0/program/ucpgvfs1.uno.so | grep -i vfs).    If your
using GNOME-VFS it works by getting the file to a temporary local file
and when you save it puts the file back to the server, like and FTP
GET/PUT;  therefore there is no file lock and the last writer wins.
