public Map<String, Set<ObjectPermission.Type>> getActiveConnectionPermissions() {
        return activeConnectionPermissions;
    }
Returns a map of active connection IDs to the set of permissions granted
for that active connection. If no permissions are granted to a particular
active connection, its ID will not be present as a key in the map. This
map is mutable, and changes to this map will affect the permission set
directly.

@return
    A map of active connection IDs to the set of permissions granted for
    that active connection.
