Abstract:
1. A computing system comprising: an authentication server requiring registration of respective digital processing system prior to providing authentication services to the corresponding ones of the digital processing systems, said authentication services being for authenticating unauthenticated users at respective client systems seeking to access resources in said computing system; a backend server registered with said authentication server, said backend server to receive a redirected request and forward said redirected request to said authentication server, said backend server to receive an authentication result from said authentication server as a response to forwarding said redirected request; and a server system to receive a request to access a resource from a user at a client system, said server system not being registered with said authentication server and said server system to redirect said request as said redirected request to said backend server if access to said resource by said user is not yet authenticated, said server system to receive said authentication result as a response to said redirect, said server system permitting said user to access said resource if said authentication result indicates that said user at said client system is authenticated without having to register said server system with said authentication server, wherein said server system and said backend server are provided as respective separate digital processing systems, wherein said authentication server contains a list of systems authorized to request authentication of users, wherein said backend server is included in said list of systems by virtue of being registered with said authentication server such that said authentication server provides authentications services to said backend server, and wherein said server system is not included in said list of systems such that said authentication server does not provide authentication services directly to said server system, thereby requiring said server system to redirect said request to said backend server for authentication services from said authentication server.
