Spring LDAP and Spring Boot configuration

Question

I have educational problem:

There are virtual machine with windows server 2003 (AD) with users and their passwords. Connection to the machine is established (ip:192.168.56.101:389).

The purpose of the web application is to enable the user to change his password in AD.

Problem: can't configure connection to windws server 2003.

I started from this tutorial https://spring.io/guides/gs/authenticating-ldap/

When I try to log in as "Jack Wood" and pass "1234" I got error.

org.springframework.security.authentication.InternalAuthenticationServiceException: 
Uncategorized exception occured during LDAP processing; 
nested exception is javax.naming.NamingException: 
[LDAP: error code 1 - 00000000: LdapErr: DSID-0C090627, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, vece ]; remaining name 'cn=Jack Wood,cn=Users'

Please check application.properties .

WebSecurityConfig

package hello;

import java.util.Arrays;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.encoding.LdapShaPasswordEncoder;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.ldap.DefaultSpringSecurityContextSource;

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

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

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .ldapAuthentication()
                .userDnPatterns("cn={0},cn=Users")
                .groupSearchBase("ou=groups")
                .contextSource(contextSource())
                .passwordCompare()
                    .passwordEncoder(new LdapShaPasswordEncoder())
                    .passwordAttribute("userPassword");
    }

    @Bean
    public DefaultSpringSecurityContextSource contextSource() {
        return new DefaultSpringSecurityContextSource("ldap://192.168.56.101:389/");
    }

}

HomeController

package hello;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HomeController {

    @GetMapping("/")
    public String index() {
        return "Welcome to the home page!";
    }
}

Application

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

Answer 1

Try changing

spring.ldap.username=cn=Jack Wood,cn=Users,dc=GRSU,dc=local

to

spring.ldap.username=cn=Jack Wood,cn=Users

Does that help?

My understanding is that the username uses the relative domain name (rdn) as opposed to the absolute domain name (dn).
