Java SSO:针对Active Directory的Kerberos身份验证

Question

我仍在尝试为SSO(在*nix上运行)找到基于Java的解决方案,我可以在JBoss上使用它来针对Active Directory /域控制器进行授权.我最初尝试通过NTLM执行此操作,但放弃了因为它在Windows Server> = 2008上不受支持.

因此,我正在尝试使用Kerberos实现此功能,但似乎无法找到正确/可行的解决方案.请指出正确的方向,说明如何设置这样的配置,如何验证Active Directory和/或域控制器,以便:

1. 找出该帐户是否有效
2. 获取用户的组列表

任何帮助表示赞赏!

UPDATE

我正在使用jcifs-ext-0.9.4和jcifs-krb5-1.3.12开发解决方案.我按如下所述设置了web.xml:

<web-app>
  <!-- servlet / servlet-mapping / welcome-file-list skipped -->

 <filter>
 <filter-name>auth</filter-name>
 <filter-class>jcifs.http.AuthenticationFilter</filter-class>

 <init-param>
 <param-name>java.security.auth.login.config</param-name>
 <param-value>/WEB-INF/login.conf</param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.spnego.servicePrincipal</param-name>
 <param-value>HTTP/testconn@mydomain.com</param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.spnego.servicePassword</param-name>
 <param-value>supersecret</param-value>
 </init-param>

 <init-param>
 <param-name>sun.security.krb5.debug</param-name>
 <param-value>true</param-value>
 </init-param>

 <init-param>
 <param-name>java.security.krb5.realm</param-name>
 <param-value>mydomain.com</param-value>
 </init-param>

 <init-param>
 <param-name>java.security.krb5.kdc</param-name>
 <param-value>testdom01.mydomain.com </param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.smb.client.domain</param-name>
 <param-value>TESTDOMAIN</param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.http.enableNegotiate</param-name>
 <param-value>true</param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.http.basicRealm</param-name>
 <param-value>mydomain.com</param-value>
 </init-param>

 <init-param>
 <param-name>jcifs.http.domainController</param-name>
 <param-value>testdom01.mydomain.com</param-value>
 </init-param>

 </filter>
 <filter-mapping>
 <filter-name>auth</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>

如果尝试访问应用程序,这会导致以下堆栈跟踪:

为此,您实际上需要使用LDAP.幸运的是,Java对Kerberos和LDAP都有坚实的支持.详细程序见http://java.sun.com/products/jndi/tutorial/ldap/security/gssapi.html.

步骤概述: - 对Kerberos进行身份验证 - 使用Kerberos承担用户身份 - 执行GSSAPI绑定到Active Directory LDAP服务器 - 通过LDAP检索组列表
