LDAP身份验证错误Spring Boot安全性

Question

我正在遵循指南（https://spring.io/guides/gs/authenticating-ldap/），并且具有以下课程：

配置类

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.ldapAuthentication()
                .userDnPatterns("uid={0},ou=people")
                .groupSearchBase("ou=groups")
                .contextSource()
                .url("ldap://localhost:8389/dc=springframework,dc=org")
                .and()
                .passwordCompare()
                .passwordEncoder(new BCryptPasswordEncoder())
                .passwordAttribute("userPassword");
        
        
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.authorizeRequests()
                .anyRequest().fullyAuthenticated()
                .and().formLogin();
    }
}

控制器类

@RestController
public class HomeController {

    @GetMapping("/")
    public String getAll()
    {
        return "Welcome All";
    }
}

LDAP配置文件（在类路径中）

我试图通过表单登录使用给定的uid和密码登录几次，并且每次浏览器中出现以下每次错误

 Caused by: javax.naming.CommunicationException: localhost:8389
 Caused by: java.net.ConnectException: Connection refused: connect

我是否必须在其他地方显式启动LDAP服务器，或者我错过了什么？

编辑- application.yml

spring:
  ldap:
    embedded:
      port: 8389
      ldif: "classpath:ldap-data.ldif"
      base-dn: "dc=springframework,dc=org"
      url: "ldap://localhost:8389/"
