Distributed cluster authentication model based on CAS

In recent years SSO (Single Sign-On) is widely used especially in enterprise environment. But the traditional SSO authentication process is general served by only one authentication node. In some condition, it may become the bottleneck of the whole SSO system, especially when dealing with huge requests. So aiming to solve the problem talked above, in this paper, we proposed a distributed cluster authentication model based on a famous open source project CAS, with certain modifications to the original workflow of CAS and designing a dynamic feedback algorithm with dynamic factor, all of which will make distributed cluster system with high performance and stability.
