The problems are mostely fixed.  I'm using this setting for a long
while now.  The ownership is the one of the UNIX user and group,
but that doesn't change the fact that you can read and change the
permissions.  You can even fetch the user and groups from the Samba
server using mkpasswd and mkgroup.  Looks like this in my environment:

  $ mkpasswd -L calimero -S_ -U root,corinna
  Unix User_root:unused:10000:99999:,S-1-22-1-0::
  Unix User_corinna:unused:10500:99999:,S-1-22-1-500::

  $ mkgroup -L calimero -S_ -U root,users
  Unix Group_root:S-1-22-2-0:10000:
  Unix Group_users:S-1-22-2-100:10100:
