[Samba] configure roaming profile

[Pol Hallen]

Hi folks :-)

Using samba4.9.5 standalone I created several users and password as 
windows machines

from windows, users can access to samba using own data without insert 
any user and password

Now I modify profile of users inserting \\srv1\home on windows account 
(I'd like using roaming profile) but there're some problems:

process_usershare_file: stat of /var/lib/samba/usershares/homes failed. 
Permission denied
WARNING: Failed to create BUILTIN\Administrators group!  Can Winbind 
allocate gids?

thanks for help!

Pol
