AUTHENTICATION SYSTEM AND AUTHENTICATION METHOD

摘要

An authentication method for a system comprising multiple intramural LANs connected with a central server comprises a step of issuing a school ID from a central server to an intramural server via the Internet, a step of informing a user via a client computer connected to the intramural server that the user is authorized to use a first application in the intramural server and a second application in the central server when a login request is received from the client computer, a step of transmitting the school ID from the intramural server to the central server when a request to use the second application is received from the client computer, and a step of permitting the client computer to use the second application when the school ID is received by the central server. <IMAGE>
