Explicit vs. Inherited Privileges
"Default" folder privileges
On an Appleshare File server, each folder can have its own privileges
assigned to it.When the administrator is setting up the server
for the first time, all privileges default to the administrator
as the owner, and no one else has privileges. But once the server
is set up, and users start creating folders on the server, by
default, any new folder will start off with the privileges of
its parent--its enclosing folder-- except for the "Owner", which will always be the user who created the folder.
Under normal circumstances, when a folder is moved around on the
server, to another enclosing folder, the privileges stay with
it. They are "explicit".
There may be times when you want a folder to always adopt the
privileges of its parent folder, even as it is moved around on
the server. This type of privilege is called "inherited" or "adopted."
Choosing between Inherited & Explicit Privileges
An advantage to explicit privileges is that they are more secure.
It is less likely that access to a folder will be accidentally
allowed, because the folder was moved on a server. Explicit privileges
would be preferred for confidential information.
One advantage to using inherited privileges is that server startup
time may be reduced. When the server is starting up, it must validate
the information in the server volume's PDS files (see "How privileges are stored"). If each folder has explicit privileges, they must all be checked.
When folders have inherited privileges, they are using a flag
that indicates "same as parent" so privileges for that folder
do not need to be validated. If you've got a large volume with
lots of folders, and you're noticing that its taking a very long
time for the server to start up, consider changing some of your
explicit privileges into inherited, where appropriate.
How to change privileges from Explicit to Inherited
There are different ways of setting privileges of folders on an
AppleShare server.
- From the server, using the Web & File Admin program:
- To change a single folder's privileges:
- Show Disk & Share Points
- Navigate to the folder whose privileges you want to change.
- Select that folder and click on the "Privileges" button.
- Change the radio button to "Use enclosing folder's privileges" if you want the privileges to be inherited, or
- "Set privileges for this item" if you want the privileges to be
explicit.
- To change the privileges of every folder within a given folder
- Show Disk & Share Points
- Navigate to and select the parent folder
- Hold down the Option key while selecting the "Enclosing Folder" button, and select explicit
or inherited, from the dialog box.
- From a workstation
- To change privileges on a single folder
- Log into the file server (you must be the folder's owner or an
administrator of the server to change privileges from a workstation;
this is determined by the user name you use to log in to the file
server).
- Mount the volume where the folder resides.
- Select the folder in the Finder.
- Choose "Sharing…" from the File menu.
- Check the "Use enclosing folder's privileges" box to give the
folder inherited privileges, or UNCheck the box to give the folder explicit privileges.
- To change privileges on all enclosed folders:
- Use the "Copy these privileges to all enclosed folders" feature. Although the privileges on enclosed folders
will be the same as the enclosing folder, they will be explicit
privileges. From a workstation, you do not have the option to
make all enclosed folders "inherit" their privileges.
