I hope i was clear.
By default in UNIX new file and folder are group-owned by the POSIX
primary group of the user that create it.
By default, vfs_acl_xattr take into account POSIX primary group and
have permissive setup for CREATOR_GROUP.
The result is that, apart doing some configuration, all users have
access (at least read access, mostly write access) to all newly created
file and folder.

Ah! Damn me! I've forgot it!
It is needed to add to [globals] in smb.conf:
idmap config DOMAIN_NAME : unix_primary_group = yes
right... excuse me...
