数字化校园统一身份认证平台的构建

建设数字化校园是推动当前教育信息化的重要系统工程，而对校园原有各个信息孤岛的业务系统进行合理的整合更是十分必要的，也是当前数字化校园研究的重点。文中根据数字校园建设的需要，介绍了基于门户系统的LDAP与CAS结合的统一身份认证平台的解决方案，系统用户信息的管理使用LDAP实现，单点登录使用Yale大学开发的CAS认证。通过构建的统一身份认证平台，整合了资源，降低了开销，使得资源得到了合理利用，对建设数字化校园起到了很好的效果。

Construction of Digital Campus Uniform Identity Authentication Platform

The construction of digital campus is the critical system engineering to promote the education informatization,and it is necessa-ry to integrate businesses of every single original information reasonably,it is also the focus of the current research in digital campus. According to the need of the digital campus construction,describe the solution of unified identity service adopted the LDAP integrated CAS system,which based on portal. The system management uses LDAP to achieve and single sign-on uses CAS certification developed by Yale University. Through the uniform identity authentication platform,integrating resources,reducing cost,make the rational use of resources. It will play a very good effect in the construction of the digital campus.
