Requests for User Services on networked computers running on different platforms with different Authentication, Authorization and Auditing (AAA) Security Systems are processed through an AAA Services Manager Server and Web Services Servers. The AAA Services Manager Server communicates requests for User Services to Web Services Servers using corresponding URL Web addresses. Web Services correspond to their respective Authentication Security Systems and Authorization Security Systems through which User Services may be obtained. The Web Services Servers act to access, for User validation, the respective Authentication Security Systems and Authorization Security Systems according to their individual languages and computing platform requirements.
