PURPOSE: A single sign on login system using an authentication agent based on the "Kerberos protocol" is provided to enable a user to access to an information system and service at one time through single user authentication without a re-authentication procedure. CONSTITUTION: A server connects to a communication network, such as the Internet communication network or other wire/wireless communication network, to transfer the information, and approves the information request. A client requests an access to the server. An authentication server generates a ticket needed to exchange the service and the information between the server and the client. An authentication agent server connects the different port architecture among the server, the client and the authentication server.
