Subject: [PATCH 540/540] extras: Disable write-behind for group samba.

when write-behind is enabled with Samba it could be a
source of data corruption. The translator, while
processing a write call, immediately returns success but continues
writing the data to the server in the background. This can cause data
corruption when two clients relying on Samba to provide data consistency
are operating on the same file.
