Java 单点登录 : Kerberos authentication against Active Directory

Question

我仍在尝试为 SSO(在 *nix 上运行)寻找基于 Java 的解决方案，我可以在 JBoss 上使用它来对 Active Directory/域 Controller 进行授权。我最初尝试通过 NTLM 执行此操作，但放弃了，因为 Windows Server >= 2008 不支持它。

因此，我尝试使用 Kerberos 来实现它，但似乎无法找到正确/可行的解决方案。请指出正确的方向，解释如何设置此类配置，如何针对 Active Directory 和/或域 Controller 进行验证，以便:

1. 查明账户是否有效
2. 获取用户的组列表

感谢任何帮助!

我正在研究使用 jcifs-ext-0.9.4 和 jcifs-krb5-1.3.12 的解决方案。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，这将导致以下堆栈跟踪:

为此，您实际上需要使用 LDAP。幸运的是，Java 对 Kerberos 和 LDAP 都有可靠的支持。详细流程在http://java.sun.com/products/jndi/tutorial/ldap/security/gssapi.html .

步骤概述:

• 向 Kerberos 进行身份验证
• 使用 Kerberos 假定用户身份
• 执行 GSSAPI 绑定(bind)到 Active Directory LDAP 服务器
• 通过 LDAP 检索组列表
