Working with permissions is important in a DISE Enterprise system with a lot of users, players, and playlists. Permissions may be set in a hierarchy and thus affect all, or only some items. Permissions restrict certain operations to be performed on an item. The operations available for restriction are:
Default permissions, or catch-all permissions, may apply to all users, or single users, for all entities of a certain type for instance players or playlists. You can combine default permissions with "regular" permissions to create catch-all permission rules. To create a default permission that applies to all users (for all entities of a type), type in "all" and select "All users" in the list or simply do not enter anything in the User field.
Howto: Users should not be able to see any players except player X:
A default permission is created for all users.
The default permission is set to unchecked for all operations (Read, Add/Delete, Change, Publish, Permissions).
Next, go into the permissions setting for player X and make exceptions for all users.
