CAS Tomcat实现单点登录

最近这两天在搞单点登录，第一次使用老出状况。以下是配置过程：

1、安全证书

　　A）、生成证书KeyStore

　　　　keytool -genkey -alias pwd123 -keyalg RSA -keystore server.keystore

　　B）、导出证书

　　　　keytool -export -file client.crt -alias pwd123 -keystore server.keystore

　　C）、在客户端导入证书

　　　　keytool -import -keystore %JAVA_HOME%/jre/lib/security/cacerts -file client.crt -alias pwd123

2、配置服务器端Tomcat　　

　　1.修改server.xml

　　<Connector
           port="8443" minSpareThreads="5" maxSpareThreads="75"
           enableLookups="true" disableUploadTimeout="true"
           acceptCount="100"  maxThreads="200"
           scheme="https" secure="true" SSLEnabled="true"
           keystoreFile="keystore/server.keystore" keystorePass="pwd123"
           clientAuth="false" sslProtocol="TLS"/>

　　CAS (Central Authentication Service)是Yale大学的ITS开发的一套JAVA实现的开源的SSO(single sign-on)的服务。该服务是以一个java web app(eg:cas.war)来进行服务

3、客户端添加测试应用

　　配置应用WEB.XML文件
