Changes for 6744317 would allow a group to become owner of a file from CIFS point of view. 
This basically means that whoever is member of that group would inherit owner's implicit permissions. On the other hand, this group has to be translated to a uid in ZFS. Basically ZFS doesn't support such semantic of having a group as an objects owner and mapping the group to a uid wouldn't provide such capability.

The result is administrator or members of Domain Admins or Administrators group could be denied access to files that they have created.

I'm reverting the changes made for 6744317 until the issue of having a group as owner can be supported properly.
