The application of cross-domain single sign-on in municipal portal

According to the requirements of the multiple municipal management information system integration, the principle and method for realizing cross-domain single sign-on in the municipal portal system is proposed. Based on analysis of the common single sign-on technology, this paper discusses designs of a CAS-based municipal portal single sign-on system. By storing user´s authentication information on CAS server, this method solves the problems in cross-domain authentication and realizes the cross-domain single sign-on. Practical application shows that through the improvement of common CAS, the authentication and authorization can be separated, and municipal information system integration and sharing can be realized through established single sign-on municipal portal, thus providing convenience for the users to quickly access to the resources.
