[K12OSN] File locking in OpenOffice with remote mount

[Sudev Barar]

Maybe OpenOffice forums are proper place but I think I can get much
wider GURU network here.
In one of the networks k12ltsp is setup with two NIC configuration.
While most of the user files are in their home directories for some
reasons that can not be helped some files are being accessed through
mounted share from a win2k server.
I have observed that while OpenOffice can be configured to allow the
second (and subsequent) instance of file opening as "READ ONLY" I am
unable to do that when accessing files from the shared directory and
both (or more) users end up in full "READ-WRITE" sessions.
Would this also happen if I mount exported directory from another
Linux box? My line of thought is that solution lies in using proper
mount options (rather than defaults).
Any inputs would be welcome.
