The research and design of unified authentication system based on CAS

With the continuous development of information construction, the application of digital campus system is increasing, the network scale expanding gradually, access control, and information security problem increasingly prominent. The original decentralized independent certification, the independent authorization, the independent account management model has been unable to meet the current and future development requirements, to improve the efficiency of information utilization, office management level, realize the informatization management, used in the construction of digital campus information service platform, unified interface and the combination of the unified identity authentication system is particularly important. According to the characteristics of the development of digital campus, based on the unification of the CAS and LDAP authentication solution, and the overall architecture design, for the digital campus application system integration and lay a good foundation for further development.
