I don't think this does what you think, from 'man smbclient':
notify <dir name>
Query a directory for change notifications. This command
recursive filechangenotify call for all possible changes. As
changes come in will print one line per change. See
https://msdn.microsoft.com/en-us/library/dn392331.aspx for a
description of the action numbers that this command prints.
This command never ends, it waits for event indefinitely.
So I think for this to work, you would have to keep a connection open to
sysvol on the PDC Emulator at all times. I have never used 'notify', so
I am guessing here, the above seems to be the total of the documentation
It could just be the most underused part of Samba ;-)
