使用 Spring Security 使用 Active Directory LDAP 进行身份验证时出现错误凭据

Question

我正在尝试使用 Spring Security 在我的 REST 控制器前执行身份验证和授权，该控制器也使用 SSL 进行保护。 我拥有的代码主要来自https://spring.io/guides/gs/authenticating-ldap/ 上的示例

该应用程序使用嵌入式 LDAP 服务器正常工作，如链接中所示。 我连接到我的主页 https://localhost:9000/training/trackerHome 并使用用户“ben”和密码“benspassword”（如链接中指定的）登录。 一切安好。

但是，当我更新我的属性并尝试连接到真正的 LDAP 服务器时，我总是在登录页面上收到显示“Bad Credentials”的错误消息。 错误日志如下所示：

我的部分困惑是密码的处理。 我不确定要为密码编码器指定什么（如果有）？ 我担心我可能正在对已经编码的密码进行编码。 我已经尝试了所有可能的密码编码器类型，而且根本没有使用密码编码器。 仍然收到错误凭据错误。

使用嵌入式 LDAP 服务器时的 application.properties：

ldap.server.url=ldap://localhost:8389/dc=springframework,dc=org
spring.ldap.username=
spring.ldap.password=

spring.ldap.embedded.ldif=classpath:test-server.ldif

任何想法我做错了什么，使与真正的 LDAP 服务器的身份验证总是返回“错误的凭据”？

Answer 1

实际 LDAP 中的密码编码器是什么？ 你确定 ldap.password.encoder 等于它。 例如，如果是 sha1，则 ldap.password.encoder 的值将是 SHA-1。 如果您不想对密码进行编码。 请按如下方式修复它。 希望对你有用。

import org.springframework.security.crypto.password.NoOpPasswordEncoder;

    switch(ldapPasswordEncoder) {
      case "none":
        passwordEncoder = NoOpPasswordEncoder.getInstance();
        break;
     ....
   }
