Q: What is CARSI user authentication process?

A: In CARSI, user authentication is composed of two parts: user authentication and application visit. Before visiting a service provider and an application, user identity authentication is required. There are two workflows to get this.

a) User authentication before application visit

A user first visits CARSI directory service http://ds.carsi.edu.cn and select his home institution. Then, he types in the username and password in his home IdP login page. After successfully authenticated, the user types in the application url in the browser and is redirected to the service directly without any further authentication.

b) Application visit before user authentication

A user visits a CARSI SP application, for example http://www.ieee.org. Guided by the application, the user selects CERNET CARSI Identity Federation and visits http://ds.carsi.edu.cn or his home institution login page. The user types in his campus-network username and password. After a successful authentication, he can access the application webpage he first visited directly with automatic web page redirection.
