[Samba] File locking issue

Hi everyone:
I posted this a couple of weeks ago and got no response. My client is
still stuck with this issue and I am quickly running out of ideas to try.
Does anyone have any ideas/suggestions? This is a long-term customer
and so far their server has provided outstanding service - until now.
I have a client with an older server that is running into a weird file
locking problem.
The server is running FC2, samba 3.0.7 and kernel 2.6.10.
They have recently installed AutoDesk Revit, which is apparently some
sort of collaborative design software. Revit keeps a central repository
and then allows different clients to access it.
What is happening is that only the person who created the file has
read/write access to it - even after s/he closes the file.
Here's a log from the workstation that creates the file. From what I
understand, the user 'johan' created the file and then tested read/write
ability.

If they put the *central.rvt file on a WinXP workstation, everything
works fine - so this has to be some sort of filelocking issue.
Per the recent 'Problems with oplocks' thread, I tried 'kernel oplocks =
no' but it has not made any difference.
Here's my smb.conf; the data share is the one experiencing the problem.

Linux stuff has made big progress over the competition. When things sit

settle for an hourglass.
