Owner Rights
In the Apple File Sharing environment, an owner is a user who can change
access rights. In the NetWare environment, users can change access rights if
they have been granted the Access Control right for the folder. In NetWare, an
owner means the one who created the file. A NetWare owner has no rights by
virtue of ownership. In the NetWare environment, the owner is the current
user if he has Access Control rights to the folder.
If the user does not have Access Control rights, the NetWare owner will be
shown if the NetWare owner is not the current user. If the current user does
not have rights to change access and is also the NetWare owner, a message to
"Use NetWare Utility" is displayed in the Owner field.
In Apple File Sharing, there can be more than one owner. If you change the
owner, Access Control rights are added to the new owner, but are not remove
from the current owner. In NetWare, there are two ways to have Access
Control rights: (1) have the Access Control right and (2) have the Supervisor
right. Adding a new owner only adds the Access Control rights, not the
Supervisor right. If the current owner already has the Supervisor right through
other NetWare utilities, that right will remain. The Supervisor right also gives
full file access rights. This means that if you are the current user and have the
Supervisor right, you also have read/write access and you cannot change those
rights.
Display only allows for one owner. If multiple users have file access rights,
only the current user is shown in the Owner field. This means you could
change the owner (which in NetWare simply means adding the Access
Control right to the new user) and when you open the file sharing dialog box
again, you will be listed as the Owner, even though you have just given
ownership or the Access Control right to someone else.
User / Group
Only one User/Group can be displayed for a folder, although NetWare allows
multiple users and groups to be assigned file access rights. If both Users and
Groups have access to a NetWare folder, Groups are displayed before Users.
The Group with the most access rights is preferred over Groups with lesser
access rights. Only users or groups with explicit rights (not inherited rights)
are shown in the User/Group field. Users and Groups with inherited rights are
not shown in the dialog box nor is there any indication that there are Users and
Groups with inherited rights.
