Standard Permissions
There are four types of standard POSIX access permissions that you can assign to a
share point, folder, or file: Read & Write, Read Only, Write Only, and None. The table
below shows how these permissions affect user access to different types of shared
items (files, folders, and share points).
Note: QuickTime Streaming Server and WebDAV have separate permissions settings.
For information about QTSS, refer to the QTSS online help and the QuickTime website
(www.apple.com/quicktime/products/qtss/). You’ll find information about Web
permissions in the Web technologies administration guide.
Explicit Permissions
Share points and the shared items they contain (including both folders and files) have
separate permissions. If you move an item to a different folder, it retains its own
permissions and doesn’t automatically adopt the permissions of the folder where you
moved it. In the following illustration, the second folder (Designs) and the third folder
(Documents) were assigned permissions that are different from those of their parent
folders:
When ACLs are not enabled, you can also set up an AFP or SMB/CIFS share point so
that new files and folders inherit the permissions of their parent folder. See “Changing
Apple File Settings for a Share Point” on page 35, or “Changing Windows (SMB/CIFS)
Settings for a Share Point” on page 36.
