Abstract

A method and system for providing a single logon system for logging onto multiple server computers without modification of the server computers. The logon system is provided by a portal computer that implements a portal web site through which users of client computers can access multiple server computers that implement various 'accessible' web sites. The portal web site provides to the client computers web pages with links that each identify accessible web sites. When a user of a client computer selects a link to an accessible web site, a message is sent to the portal web site that identifies the accessible web site. The portal web site uses the definition of logon messages to control the logging on of the user to the identified web site in such a way that the logon appears to the identified web site as being performed by the user and that the identified web site does not need to be modified to accommodate the logging on of the user via the portal web site.
