Question

我已经采用了Spring SAML示例（参见4.2 in this guide），该示例与开源登录页面SSO一起使用，并尝试添加支持以使用WSO2 Identity Server作为额外的IDP服务。为此，我通过为IS添加元数据xml文件来更改spring SAML示例项目，并将一个IS元数据条目添加到securityContext.xml。

在运行spring应用程序时，我现在可以看到使用IS登录的选项，当我被重定向到它时，我可以成功登录WSO2。但是，spring应用程序会在IS SAML响应上抛出异常，因为它与InResponseToField不匹配。

2015-01-05 09:54:12,845 line="org.springframework.security.saml.log.SAMLDefaultLogger.log(SAMLDefaultLogger.java:127)" thread="http-nio-8080-exec-4" class="org.springframework.security.saml.log.SAMLDefaultLogger" AuthNResponse;FAILURE;0:0:0:0:0:0:0:1;com:vdenotaris:spring:sp;localhost;;;org.opensaml.common.SAMLException: InResponseToField of the Response doesn't correspond to sent message ae2dab0fb8b0g8e49971b91a73e91i

从调试应用程序开始，响应消息不会被识别为属于与请求消息相同的会话。我说从这两条日志消息中，第一条是在发送AuthRequest时记录的，第二条是在收到响应时：

2015-01-05 09:53:20,867 line="org.springframework.security.saml.storage.HttpSessionStorage.storeMessage(HttpSessionStorage.java:93)" thread="http-nio-8080-exec-1" class="org.springframework.security.saml.storage.HttpSessionStorage" Storing message ae2dab0fb8b0g8e49971b91a73e91i to session 26D3B7D9E33F26A7A5092BF6909B9D13

IS SAML响应是：

作为参考我附加了我为WSO2 IS添加的元数据xml文件（我必须给它一个'localhost'的entityID，因为这是WSO2 IS坚持要返回的（默认情况下它使用主机名））。

根据要求，我已在dropbox上保存了浏览器HTTP消息的日志。

Spring SAML和您的IDP WSO2服务器都部署在同一个域 - localhost 上。这就是：

Spring SAML创建一个HTTP会话（ JSESSIONID - 82F3ECD1A1E4F9B7DB0134F3129267A5）并初始化单点登录
WSO2接受请求并对用户进行身份验证，但会创建自己的会话（JSESSIONID - C34B21931C53080487B5B9BA6EB490D2）并将用户重定向回Spring SAML
容器运行Spring SAML使用 JSESSIONID （C34B21931C53080487B5B9BA6EB490D2）接收cookie，但由于它不识别这样的会话，因此会创建一个新的（E712A8422009613F6FD3901327690726）
Spring SAML尝试根据原始请求验证收到的SAML消息，但由于原始会话现已消失，因此无法找到它

解决此问题的最简单方法是更改Spring SAML或WSO2的会话cookie名称。您还可以在不同的域上部署应用程序（例如，通过在hosts文件中为您的localhost提供别名 - /etc/hosts或%systemroot%\system32\drivers\etc\hosts）

Spring SAML与WSO2身份服务器集成，无法识别SAML消息
