Mac OS X Server: A Group Cannot Own a Share Point

In AppleShare and Mac OS versions prior to Mac OS X, a group could be specified as the owner of a shared folder or volume. This feature is not available in Mac OS X.
Mac OS X and Mac OS X Server use Unix-style permissions on files and folders. In this system, only a user can be the owner of a file or folder. Therefore a group cannot be assigned as the owner of a share point.
