If the request contains a known pre-shared key, the CA Engine automatically assigns an entity mapping to the request.
The operator can manually change the entity mapping. This is done by entering the entity search string (such as the name of the entity) in the string input box and then clicking the Search button adjacent to the box. The first few dozen entities matching with the search parameters are then displayed in a drop-down list.
The entity selection can be removed by clicking the Change button next to the menu. If the entity is already set, it can be cleared by clicking the Reset button.
