即使在 IDP 使用 SAML 成功登录后,获取身份验证对象仍为空

【中文标题】即使在 IDP 使用 SAML 成功登录后,获取身份验证对象仍为空【英文标题】:Getting authentication object is null even after successfully login by IDP using SAML 【发布时间】:2015-05-31 17:50:53 【问题描述】:我已经在我的应用程序中配置了 spring-saml 和 spring security。我给出了不同的 url 模式来识别请求。如果我在应用程序 URL 中附加 /rest ,那么它将创建带有基本身份验证的 spring-security 上下文。如果我在应用 URL 中附加 /saml ,那么它将填充 IDP 登录页面并在成功登录后重定向到 index.html。
但是我再次被重定向到 login.html 页面而不是 index.html。在eclipse调试并在这里和那里放置一些日志之后,我得到了没有可用的身份验证对象。
我已阅读此 jira link 并将 spring-security 版本更新为 3.1.4.RELEASE 但它没有解决我的问题。
经过一番努力后,我发现 saml 安全上下文正在被 filterChainProxy doFilter 方法清除,并且将身份验证设置为空,然后重定向到需要身份验证的安全目标 URL,但该 URL 不存在。因此它重定向到登录页面。
我搜索了很多,但没有找到任何使用 saml 身份验证通过 j_spring_security 检查的方法。
我在下面附上了我的 saml-security.xml 和 spring-security.xml 文件

谁能帮我解决这个问题。 提前致谢。
【问题讨论】:
您能否上传您正在部署的应用程序并发布您正在使用的 Tomcat 的确切版本?我会尝试重现您的问题。 @VladimírSchäfer 我已经用我的 saml-security 和 spring-security xml 文件更新了我的问题。 我可以通过这些设置使用 IDP 登录。但是,我无法访问任何保护资源,例如以 xml 粗体显示的 index.html。由于拦截网址,它会将我重定向到登录页面。 【参考方案1】:苦苦挣扎了将近一周,终于解决了这个问题。
通过 Eclipse 进行调试时,我在 SAMLAuthenticationProvider 中找到了根本原因,有一个方法 getEntitlements
导致了问题。
protected Collection<? extends GrantedAuthority> getEntitlements(SAMLCredential credential, Object userDetail)
if (userDetail instanceof UserDetails)
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UserDetails) userDetail).getAuthorities());
return authorities;
else
return Collections.emptyList();
这里检查userDetail对象是否是UserDetails类的instanceOf,然后返回所有权限列表,否则返回空权限列表。
返回UserDetails
对象的基于表单的身份验证很好,但如果用户通过IDP 启动的SSO 登录,则将返回UsernamePasswordAuthenticationToken
类型的对象。因此,它使用 userDetail 对象获得了空的grantedAuthourity 列表。
所以我在我的应用程序中扩展 SAMLAuthenticationProvider
并覆盖下面的方法
@Override
public Collection<? extends GrantedAuthority> getEntitlements(SAMLCredential credential, Object userDetail)
logger.info("****** object is instance of UserDetails :"+ (userDetail instanceof UserDetails));
if (userDetail instanceof UserDetails)
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UserDetails) userDetail).getAuthorities());
return authorities;
else if(userDetail instanceof UsernamePasswordAuthenticationToken)
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.addAll(((UsernamePasswordAuthenticationToken) userDetail).getAuthorities());
return authorities;
else
return Collections.emptyList();
然后我将我的自定义 authenticationProvider 引用与我的自定义 SAMLUserDetailsService 类引用一起提供给 saml-security.xml 文件。
<bean id="samlAuthenticationProvider" class="com.mercatus.security.MercatusSAMLAuthenticationProvider">
<property name="userDetails" ref="samlUserDetailsService" />
</bean>
<bean id="samlUserDetailsService" class="com.mercatus.security.MercatusSAMLUserDetailsService"/>
上面的配置救了我。登录后我可以访问受保护的资源。
我花了整整一周的时间在 FilterChainProxy 和许多其他过滤器中进行调试,并且由于拦截器 URL,它被重定向到 FilterChainProxy。
我发布详细信息是因为它可能对面临类似问题的其他人有所帮助。
【讨论】:
嗨 Manoj,我面临同样的问题。该错误类似于“在 securitycontext 中找不到身份验证对象”。我正在我的微服务中实现 Spring Saml 集成。你能提供同样的指导吗?如果您可以提供有关您的自定义 SAMLUserDetailsService 的详细信息,也会很有帮助。谢谢。以上是关于即使在 IDP 使用 SAML 成功登录后,获取身份验证对象仍为空的主要内容,如果未能解决你的问题,请参考以下文章
Spring saml - 在SP上启动登录时如何记住请求参数,并在IdP响应后处理它们
要求使用相同的 IDP 重新进行身份验证 - Spring SAML
使用 Spring Security saml 的 IDP 会话超时
如何让两个单独的 SAML 应用程序登录到 IdP 而无需登录两次?
