4 To restrict read and write access to the shared folder and its contents, click Edit
Permissions, select “Only these registered users and groups,” and select the checkbox
next to each user and group you want to give read and write access to.
If you give a group read and write access, all users who are members have read and
write access even if their individual checkboxes are deselected.
5 To allow guest users to read the contents of a shared folder, click Edit Permissions and
select “Allow guests read-only access.” Deselect this option to disallow guest access.
Users who have permission to access a shared folder can use the AFP and SMB le
sharing protocols to access the folder.
Registered users and members of groups authenticate for read and write access by
using the name and password of their user account on the server. An external member
of a group has no account on the server, but can authenticate using the name and
password of the member’s external user account.
Guests don’t authenticate for read-only access to a shared folder. Unlike registered
users, guests don’t need user accounts on your server.
You can also change access permissions for a shared folder or any item in it by using
the Info window in the Finder. For information about setting permissions for folders
and les, switch to the Finder and then use the Help menu.
