[Samba] GPO created via samba-tool don't Copy or Backup in RSAT (invalid directory)

[Klaas TJEBBES]

I've noticed that the GPO restored by "samba-tool gpo restore" is empty, 
it has not been restored completely.

Actually, the modification I made has not been restored : Computer 
Configuration -> Strategies -> Administrative Templates -> System -> 
Logon “Always Wait for the Network at Computer Startup and Logon” to 
“Enabled”
