本文介绍CAS应用如何与MaxKey进行集成。

<h2>应用注册</h2>

应用在MaxKey管理系统进行注册，注册的配置信息如下

<img src="{{ "/images/sso/sso_cas_conf.png" | prepend: site.baseurl }}?{{ site.time | date: "%Y%m%d%H%M" }}"  alt=""/>


<h2>CAS客户端配置</h2>

本文使用JAVA WEB程序为例

jar包依赖如下

cas-client-core-3.2.1.jar

commons-codec-1.4.jar

commons-logging-1.1.1.jar

slf4j-api-1.5.11.jar

web.xml配置
