ZFS properties, see Oracke docs ex
http://docs.oracle.com/cd/E19120-01/open.solaris/817-2271/gbaaz/index.html <http://docs.oracle.com/cd/E19120-01/open.solaris/817-2271/gbaaz/index.html>

If you want full permissions on files on an SMB share, you must either connect as user root
or as an AD user that is idmapped to Unix root

Adding a user to the SMB group administrators is needed for some administration 
tasks (ex remote computer management) but root permission is the key for 
any file permission problems.

>>> Hi,
>>> I am a bit stuck in getting my ACL management straight for the CIFS shares I run. What I would like to do is to set all the ACLs from Windows. What does not work right now is to assign ownership to a sharepoint or an object below it to a different user, i.e. to set ownership as the Domain Administrator to a specific user. I get an error message that a "Restore" privilege would be missing, but the error message is unclear if that applies to the current context (Domain Administrator), or the prospective owner. I can set full control for that user, however.
