Spring Security LDAP Login Bad Credentials

Question

I'm trying to use the spring security to connect with LDAP but it always show Bad credentials problem.
I think maybe there is something wrong with my code:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(WebSecurity web) throws Exception {
        web.debug(true);
    }
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        auth.ldapAuthentication().userDnPatterns("sAMAccountName={0},OU=SupportUsers,OU=Users,OU=company,DC=ad,DC=company,DC=com,DC=pl")
            .contextSource(contextSource()).passwordCompare().passwordAttribute("userPassword");
    }
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .anyRequest().fullyAuthenticated()
                .and()
            .formLogin();
        http.csrf().disable(); //Vaadin already have built in csrf
    }
    @Bean
    public LdapContextSource contextSource () {
        LdapContextSource contextSource= new LdapContextSource();
        contextSource.setUrl("ldap://192.168.2.2:389");
        contextSource.setBase("dc=ad,dc=company,dc=com,dc=pl");
        contextSource.setUserDn("CN=lister,OU=SupportUsers,OU=Users,OU=company,DC=ad,DC=company,DC=com,DC=pl");
        contextSource.setPassword("examplePassword");
        contextSource.setAnonymousReadOnly(false);
        contextSource.setPooled(true);
        contextSource.afterPropertiesSet();
        return contextSource;
    }
}

I can't find a bug in a code, maybe I'm doing something in a wrong way. Here is my pom.xml:

Did I made something wrong? Maybe there is a problem with password encoding? Greetings, Rafał

Answer 1

public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

    auth.ldapAuthentication().userSearchFilter("(sAMAccountName={0})")
    .contextSource(contextSource());
}

It works, I've just changed that method.
