Does this mean you are running Samba4 now? Because Samba4 still contains the oplocks configuration parts and even the code checks whether oplocks (normal and level2) are enabled (at least in 4.1 where I checked). Maybe just an oversight?
Yes, Samba 4. It still supports SMB1, so of course the configuration parameters will still be there. But modern clients will negotiate SMB2/3. From http://support.microsoft.com/kb/296264 (and various other places):
You cannot turn off opportunistic locking for SMB2.
We do plan to release a sort of "SMB extended controls" app, with which you can tweak more advanced settings, similar to editing the Windows registry. So when that is available (should be soon), you should be able to switch off SMB2/3 support and disable oplocks for SMB1.
Ok, that sounds great. Thanks for the update. I don't really care about SMB2 as AFAIK the main benefit is speed which is less important than data integrity. Unfortunately I have to run a badly implemented database software which simply breaks stuff if oplocks are enabled.
The SMB Plus app is available now. If it's not showing up on your Available Apps list, you can grab it from here and manually install it using the Upload button.
