CAS Single logout not working

Question

我正在Java EE環境中通過CAS實現Single-Sign-On + Single-Log-Out。

在身份驗證方面我有cas-server-webapp v4.0.1。然後是2個簡單的Java + Spring MVC Web應用程序，其中cas-client-corev3.1.10。

沒有關於單點登錄的問題。如果我訪問/ app1，我將被重定向到cas-server-webapp中的cas登錄頁面。用戶+通過輸入後，我被重定向到/ app1正確的身份驗證。另外，如果我導航到/ app2，這個人會得到它的授權票。到現在爲止還挺好。

至於單註銷，也許我誤解了doc：但是這是我做的：

APP1和APP2都映射爲/註銷URL每一個Spring控制器：

@Controller 
public class LogoutController { 

    @RequestMapping("/logout") 
    public String logout(HttpSession session){ 
     session.invalidate(); 
     return "redirect:https://cas-server-host:8443/cas/logout?service=http://cas-server-host:9080/cas1/action/index"; 
    } 
} 

也就是說，我使http會話無效並重定向到cas服務器註銷url，以使票證失效。

在CAS服務器日誌中我看到，它破壞了TGT票證併發送註銷請求給各應用的CAS過濾器：

現在，假設我從/ CAS1登出，我發送回cas服務器登錄頁面。無需再次登錄，如果我訪問/ app2,我被允許導航這個應用程序，就像我還在驗證一樣，我可以訪問它的java.user.Principal和會話。這怎麼可能？不應該在/ app2中收到註銷請求摧毀了Principal和http會話？

......我的錯，正如所料，我錯過了一些東西。我必須在這兩個應用程序中包含Single Sign Out Filter和Listener：

<filter> 
     <filter-name>CAS Single Sign Out Filter</filter-name> 
     <filter-class>org.jasig.cas.client.session.SingleSignOutFilter 
     </filter-class> 
    </filter> 
    <filter-mapping> 
     <filter-name>CAS Single Sign Out Filter</filter-name> 
     <url-pattern>/*</url-pattern></filter-mapping> 
    <listener>  
     <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class> 
    </listener> 

    <filter> 
     <filter-name>CAS Authentication Filter</filter-name>
