18 Chapter 1 Overview of File Services
The User Categories Owner, Group, and Everyone
You can assign standard POSIX access permissions separately to three categories
of users:
• Owner—A user who creates a new item (file or folder) on the file server is its owner
and automatically has Read & Write permissions for that folder. By default, the owner
of an item and the server administrator are the only users who can change its access
privileges (allow a group or everyone to use the item). The administrator can also
transfer ownership of the shared item to another user.
Note: When you copy an item to a drop box on an Apple file server, ownership of the
item doesn’t change, but only the owner of the drop box or root has access to its
contents.
• Group—You can put users who need the same access to files and folders into
group accounts. Only one group can be assigned access permissions to a shared
item. For more information on creating groups, see the user management guide.
• Everyone—Everyone is any user who can log in to the file server: registered users
and guests.
Hierarchy of Permissions
If a user is included in more than one category of users, each of which has different
permissions, these rules apply:
• Group permissions override Everyone permissions.
• Owner permissions override Group permissions.
For example, when a user is both the owner of a shared item and a member of the
group assigned to it, the user has the permissions assigned to the owner.
Client Users and Permissions
Users of AppleShare Client software can set access privileges for files and folders they
own. Windows file sharing users can also set access privileges.
Standard Permission Propagation
Workgroup Manager provides a command that lets you specify which standard
permissions to propagate. For example, you can use this command to propagate only
the permission for Everyone to all descendants of a folder, and leave the permissions
for Owner and Group unchanged. For more information on how to use this command,
see “Propagating Permissions” on page 46.
