OpenOffice on Linux (POSIX) has no concept of DENY modes,
they simply don't exist on POSIX. OpenOffice would have to
use byte range locks to get the same effect. I'm not sure
if the Linux OpenOffice code does this. It is not a Samba
bug, but an application level one. I suggest you log this
on the OpenOffice bugzilla.
