Java 使用LDAP的Spring安全性-登录后出错

我已经设法使我的Spring项目与安全性和LDAP一起工作，但只与LDIF文件一起工作。现在，我正试图通过配置LDAP服务器使其正常工作，但我只做到了这一点——通过使用正确的凭据登录，我的网站没有出现任何错误，但我只能做到这一点

我一直在谷歌上搜索这些错误，但我找不到任何类似的/有用的帮助。也许曾经使用SpringLDAP的人知道如何正确地配置项目以使用LDAP服务器

以下是控制台抛出的内容：

这是我的application.properties：

spring.ldap.embedded.base-dn=dc=FOO,dc=FOO2
spring.ldap.embedded.port=8389
spring.ldap.urls=ldap://xx.x.x.xx:389/dc=FOO,dc=FOO2
spring.ldap.embedded.validation.enabled=false
spring.ldap.base=ou=MY_GROUP,dc=FOO,dc=FOO2

以及扩展WebSecurity配置适配器的cofig类：

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception
    {
        auth
                .ldapAuthentication()
                .userDnPatterns("cn={0},ou=MY_GROUP")
                .contextSource()
                .url("ldap://xx.x.x.xx:389/dc=FOO,dc=FOO2");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception
    {
        http
                .authorizeRequests()
                .anyRequest().fullyAuthenticated()
                .and()
                .formLogin().permitAll()
                .and()
                .logout().permitAll();
    }
