Click or pull down the Add Entries menu and select Add All Other Users ... to create an entry in the active ACL for all users not already listed on the ACL. If the menu item and button are dimmed, it means you already have this entry on your ACL. You can have only one such entry on an ACL.
Select the permissions you want by clicking on the desired permissions displayed in the Permissions box. Note that if you do not select any permissions, no permissions are granted and no access is allowed.
