Working with permissions is important in a Portal with a lot of users, players, and playlists. Permissions may be set in a hierarchy and affect all, or only some items. Permissions restrict certain operations to be performed on an item. The operations available for restriction are:
The user may list items in Portal.
The user may create new items or delete items.
The user may change settings for the item (for example changing what playlist a player has).
The user may communicate any changes made to the item to players.
The user may change the permissions settings for the item.
The permissions for an item (a playlist etc) is generally set in its Tools menu.
To add a permission, click Add entry or click the plus icon.
Default permissionsDefault permissions, or catch-all permissions, apply to all users, single users, or user groups, for all items of a certain type. You may combine default permissions with "regular" permissions to create catch-all permission rules.
To create a default permission that applies to all users, type in "all" and select "All users" in the list or simply do not enter anything in the User field.
Network-wide permissions can be found in the same place as 'Default permissions'.
Network-wide permissions is the baseline permission, so if no special permissions are set for a user they will have the network-wide permissions.
So for example if you want all new users not to be able to see players, you can achieve this by going into "Default permissions" -> "Players" and then turn off the 'Allow read' under the Network-wide permissions.
