java - CAS 单点注销 (SLO) 不起作用 - CAS 4.2.3

Question

我在 CAS 中遇到单点注销问题。我使用的是 CAS 服务器 4.2.3 和 Spring 3.2。我的客户端应用程序是在 Spring Security 上配置的。遵循以下文档:http://docs.spring.io/spring-security/site/docs/3.2.9.RELEASE/reference/htmlsingle/#cas-singlelogout

我有 2 个 cas 客户端 Web 应用程序。当我从其中一个 cas 客户端 Web 应用程序注销，并刷新我已登录的第二个 cas 客户端应用程序中的页面(在同一浏览器中的不同选项卡中)时，我认为登录页面会显示，因为我已经从第一个 cas 客户端应用程序执行了一次注销。但这不起作用。

我不确定我错过了什么。我已经发布了 web.xml、spring-security.xml、logout.jsp 和 cas.log 的代码片段

非常感谢任何帮助或指示。

Answer 1

显然我找到了一个问题的答案:我从一个 CAS 客户端注销，而另一个 CAS 客户端却没有注销。为此，CAS 服务器需要了解所有已注册的服务。

我认为 CAS 服务管理工具负责执行此操作。然而，这对我不起作用。看来 CAS 管理服务不这样做。尽管安装了服务管理工具并将其链接到我的 CAS 服务器，但还是不起作用。

我必须更进一步，添加一些与 RegexRegisteredService 相关的配置文件。以为服务管理工具中存在此配置，CAS 服务器似乎无法识别该配置，就像我之前提到的那样。因此，我必须将这些文件从服务管理工具复制到 CAS 服务器。在 CAS 服务器中，我将其放置在以下位置:../WEB-INF/classes/services。文件名通常类似于 AppName-UniqueID.json

json 文件看起来像这样，

{
"@class" : "org.jasig.cas.services.RegexRegisteredService",
"serviceId" : "https://<hostname>/AppName/j_spring_cas_security_check",
"name" : "App Name",
"id" : 7042148554761,
"logoutType" : "BACK_CHANNEL",
"logoutUrl" : "https://<hostname>/AppName/<Logout URL>"
}

请记住，您需要为每个 cas 客户端应用程序拥有单独的文件。

完成此步骤后，当我从 1 个 CAS 客户端注销时，我可以在其他 CAS 客户端控制台中看到 CAS 服务器的响应。现在，剩下的工作需要在 CAS 客户端完成，以识别 CAS 的注销操作并注销本地 session ，这就是我现在正在做的工作。

我是 CAS 新手。根据我的经验，我发现 CAS 文档有点含糊。它可能需要更多的清晰度。
