我拥有了你做同样的敲打，我的头抵墙式体验，并最终写入，做一个LDAP自定义身份验证提供者针对Active Directory服务器进行查询。
所以我的安全相关的豆类：
<beans:bean id="contextSource"
class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
<beans:constructor-arg value="ldap://hostname.queso.com:389/" />
</beans:bean>
<beans:bean id="ldapAuthenticationProvider"
class="org.queso.ad.service.authentication.LdapAuthenticationProvider">
<beans:property name="authenticator" ref="ldapAuthenticator" />
<custom-authentication-provider />
</beans:bean>
<beans:bean id="ldapAuthenticator"
class="org.queso.ad.service.authentication.LdapAuthenticatorImpl">
<beans:property name="contextFactory" ref="contextSource" />
<beans:property name="principalPrefix" value="QUESO\" />
</beans:bean>
然后LdapAuthenticationProvider可疑类：

然后LdapAuthenticatorImpl类：

你会注意到，有一些你可能不需要的位。
例如，我的应用程序需要保留成功登录的LDAP上下文以供用户在登录后进一步使用 - 该应用程序的目的是让用户通过其AD凭据登录，然后再执行AD-相关功能。因此，我有一个自定义身份验证令牌LdapAuthenticationToken，它传递给我（附加LDAP上下文，而不是Spring的默认身份验证令牌）。在LdapAuthenticationProvider.authenticate（）中，我创建了该令牌并将其传回;在LdapAuthenticatorImpl.authenticate（）中，我将登录的上下文附加到返回对象，以便它可以添加到用户的Spring认证对象中。
此外，在LdapAuthenticationProvider.authenticate（）中，我为所有登录用户分配了ROLE_USER角色 - 这就是让我在我的拦截url元素中测试该角色的原因。无论您想要测试哪种角色，您都希望进行匹配，甚至可以根据Active Directory组或其他角色分配角色。
最后，由此推论，我实现LdapAuthenticationProvider.authenticate（）的方式为所有用户提供了有效的AD帐户，它们具有相同的ROLE_USER角色。显然，在该方法中，您可以对用户（即特定AD组中的用户？）执行进一步测试，并且甚至在准许用户访问全部之前分配角色，甚至测试某些条件。
这不是一个真正的答案，而是一个澄清的问题 - 您是否已经将日志记录转换为Spring安全包的所有内容？ – 2008-09-17 17:52:40
我有日志记录开启了一切。没有看到任何正在记录的消息......我用我的Log4J配置更新了我的问题。 – Michael 2008-09-17 18:35:26
