Hello Chan Min wai,

Had read that page and tried to disable level2 oplocks and veto oplocks 
for doc files but had no success. My setup had worked for two month 
without the need for special oplock settings. One thing i forgott to 
mention is that i also redirect most windows folders (not Localdata) to 
the samba server, so all the temporary files office creates reside in 
the users home directory.
Seen one oplock break for normal.dotm during file opening but if i try 
to save the file only temporary files are affected and no oplock 
warnings occure.
Looking at the 4.1.5 list of fixes, this bug may affect me 
https://bugzilla.samba.org/show_bug.cgi?id=10436.

An more general question, when the defaults for samba parameters changed 
in the past it was mentioned in the Changelog or Releasenotes. Can it be 
there where no new parameters or changes introduced lately?
