基于CAS构建SSO系统的设计与实现

摘要

The number of enterprise business system is increasing with the application of information technology in enterprise. As usual, each business system needs a separate login, which inevitably brings a lot of inconvenience both in operation and management. Designing SSO system for the enterprise is an effective solution to solve the problem. A kind of solution named SSO system is discussed based on CAS construction and through the EIP system of the Agricultural Development Bank of China using this kind of solution to demonstrates the scheme.%随着信息技术在企业应用中的普及，企业业务系统的数量不断增加．通常，进入每个业务系统都需要进行一次单独的登录，这势必会在操作和管理上带来诸多不便．因此，为企业设计SSO（Single Sign On，单点登录）系统是解决以上问题的一个有效方案，论述一种基于CAS（Central Authentication Service，中央认证服务）构建SSO系统的方案，并通过在中国农业发展银行EIP系统中使用解决过程中的实践，从而论证了该方案的可行性．
