HS Full implementation of password server. It is written in Java. The SessionManager is tightly integrated with the Password service. It creates a session environment and manages user authorization.
Authorization is required only once per session no matter how many GUIs are started.
The password system automatically handles additional privileges for shift personnel. When a SessionManager starts up it registers with the Password server and receives a unique session number. The initial login dialogue follows immediately, so that every session is connected to a user. That triggers the component frame to check an internal session list. The component frame stores the response for future references.
