我遵循以下教程，以使Spring和Rest能够使用完整的安全性和无状态令牌。

我现在正在尝试将身份验证机制转换为使用Active Directory（ActiveDirectoryLdapAuthenticationProvider）。我的问题是我无法弄清楚如何到达UserDetails，因此可以使用loadUserByUsername（userName）方法。
下面是导致我出现问题的方法，注释行为过滤器提供了用户详细信息服务，但我无法弄清楚如何使用Active Directory身份验证获取此信息。
private Filter authenticationFilter() {
HeaderAuthenticationFilter headerAuthenticationFilter = new HeaderAuthenticationFilter();
//headerAuthenticationFilter.userDetailsService(userDetailsService());
headerAuthenticationFilter.headerUtil(headerUtil);
return headerAuthenticationFilter;
}
以下是我的Spring Security配置和使用的课程。
SecurityConfig
@Configuration

Spring LDAP有一个名为LdapUserDetailsService的东西，我将会说明这可能是你必须要做的事情。通常，Spring带有合理的默认值，我们只需连接正确的东西。
