CONNECTION DESTINATION DETERMINATION DEVICE, CONNECTION DESTINATION DETERMINATION METHOD, AND SERVICE COLLABORATION SYSTEM

A connection destination determination device includes a control unit for performing an approval determination process to determine that a user authentication state in a connection destination request is approved if the user authentication state satisfies the user authentication state corresponding to a collaboration service. If the user authentication state is determined to be approved in the approval determination process, the control unit responds to a source of the connection destination determination request with the connection destination of service corresponding to the collaboration service which is the search key. If the user authentication state is not determined to be approved in the approval determination process, the control unit responds to the source of the connection destination determination request with the connection destination of authentication service, in order to obtain the user authentication state that does not satisfy the user authentication state corresponding to the collaboration service which is the search key.
