我正在使用http://webmoli.com/2009/08/29/single-sign-on-in-java-platform/ 对于java中的SSO。
我有KDC Windows server 2008，因为我已经使用setsss命令为testsso用户创建了spn。并使用testsso@MYDOMAIN.COM作为jaas.con中的主体。
我在Windows 7机器中有Tomcat服务器（在AD内）。在这里我从jsp创建了一个servlet（来自webmoli本身）。
我从第三台机器Windows XP（AD内）发送该servlet的浏览器请求。
但我得到校验和失败错误。 Stacktrace as follws-

请帮帮我......
答案 0 :(得分：0)
如果我没记错的话，当使用不同的密钥对服务票据进行解密时，会抛出此错误。
ktpass /out c:\tomcat.keytab /mapuser tc01@DEV.LOCAL
/princ HTTP/win-tc01.dev.local@DEV.LOCAL
/pass tc01pass /kvno 0
是正确的...当连续使用'ktpass'时，AD会自动增加存储在AD中的密钥版本号。
