  • Method of assisting server access by use of user authentication information held in one of servers and a method of assisting management user account for use of servers
    Patent number: 5671354
    Abstract: User authentication information for network of a user and a name of a server to be accessed are sent from a client terminal to a user management equipment realized by one of servers which constitute a network system. The user management equipment sends the network address of that server and user authentication information registered for that server back to the client terminal. Using these pieces of information, the client terminal logs in that server. Each of the servers used by the user notifies the user management equipment of the actual accounts for the user at preferable times. Using the notified information, the user management equipment manages the actual accounts of each user. Each user can know the total of actual accounts for the servers used by accessing only the user management equipment.
