SpringBoot整合LDAP遇到无效验证问题， 求解答

Question

问题遇到的现象和发生背景

我正在尝试使用SpringBoot 整合 LDAP进行测试， 但却没有成功，抛出了 [LDAP: error code 49 - Invalid Credentials]的异常
这里的用户名 密码 我都是使用默认的，（cn=Manager， secret）

问题相关代码，请勿粘贴截图

applicatin.yml
spring:
ldap:
urls: ldap://localhost:389
base: dc=maxcrc,dc=com
username: cn=Manager
password: secret

LdapConfiguration.java

package com.example.ldap.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.ldap.core.LdapTemplate;
import org.springframework.ldap.core.support.LdapContextSource;
import java.util.HashMap;
import java.util.Map;

@Configuration
public class LdapConfiguration {

    private LdapTemplate ldapTemplate;

    @Value("${spring.ldap.urls}")
    private String url;

    @Value("${spring.ldap.base}")
    private String base;

    @Value("${spring.ldap.username}")
    private String username;

    @Value("${spring.ldap.password}")
    private String password;

    @Bean
    public LdapContextSource contextSource() {
        LdapContextSource contextSource = new LdapContextSource();
        Map<String, Object> config = new HashMap<>();
        contextSource.setUrl(url);
        contextSource.setBase(base);
        contextSource.setUserDn(username);
        contextSource.setPassword(password);
        //  解决乱码
        config.put("java.naming.ldap.attributes.binary", "objectGUID");

        contextSource.setPooled(true);
        contextSource.setBaseEnvironmentProperties(config);
        return contextSource;
    }

    @Bean
    public LdapTemplate ldapTemplate() {
        if (null == ldapTemplate) {
            ldapTemplate = new LdapTemplate(contextSource());
        }
        return ldapTemplate;
    }

}

运行结果及报错内容
