[Samba] GPO Filter Group/User

[Carlos A. P. Cunha]

Hello!

My Configuration:

lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:        14.04
Codename:       trusty

Version Samba:

samba-tool -V
4.4.4

My problem is, create a GPO with group Filtering, in case I want the GPO 
to be applied only to a specific group.
When I do this (Filter) it does not load the GPO, only when I leave the 
default (Authenticated User).
Is there something wrong with Samba or something different?

Regards
