[Samba] net logon scripts not running

[Gary Dale]

I am running Samba4 on a Debian/Jessie AD DC. I have a network netlogon 
share  with a single script in it. This .bat file is referenced in the 
ADUC profile and I can navigate to the netlogon share and run it, where 
it does what it is supposed to do.

However when I log onto the workstation, it never executes. For example, 
it maps a drive but the drive is not mapped after a logon.
