When using PING to backup Authentication Manager 8.2, receiving the following error:
CIFS VFS: Error -32 sending data on socket to server
The CIFS share is loaded with correct permissions; for example, a user can manually create files remotely. But when attempting to run PING to backup the user immediately gets the following errors:
CIFS VFS: Received no data, expecting 4
echo 0 > /proc/fs/cifs/OplockEnabled
Note that this value will be overwritten each time PING is re-loaded. Adding it to backup/restore instructions or a script works well so that it is set correctly each time.
