[Samba] Samba and oplocks

[ml at s-it.ch]

Hi

We've here some problems with Samba on a freeBSD-Server.

FreeBSD 6.2-RELEASE
Samba Version 3.0.25a

The problem is about locking of open files. For example when a user A
opens a excel-sheet and a user B also opens the same file, user B won't
only open this file as read-only.
We moved from a Windows Server to a freebsd based one about 2 weeks ago
and we also had some problems with dbs and mdb files.
Then I was able to fix the problem with the following entry under the
global section in the smb.conf

veto oplock files = /*.mdb/*.MDB/*.dbf/*.DBF

We have the problems with the office documents since 2 days and I can't
remember to have something changed in samba config.

I also red this article.

Now I'm wondering if someone got some more experiences with samba and the
way locks are handled?
Does freeBSD support kernel oplocks?

I also compared this behavior with our Synology NAS-Server and there seems
to be no problem with handling locks.

Thanks for your help
