How to achieve Ldap authentication using spring security (spring boot)

I have a code with me I am trying to achieve ldap authentication but I think it is not happening.

Security configuration

@EnableWebSecurity
@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class Config extends WebSecurityConfigurerAdapter {

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

        http.httpBasic().and().authorizeRequests().antMatchers("/*")
                .permitAll().anyRequest().authenticated().and().csrf()
                .disable().httpBasic().and().csrf()
                .csrfTokenRepository(csrfTokenRepository()).and()
                .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);

    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.ldapAuthentication()
                .userSearchFilter("(uid={0})")
                .userSearchBase("dc=intern,dc=xyz,dc=com")
                .contextSource()
                .url("ldap://192.168.11.11:1234/dc=intern,dc=xyz,dc=com")
                .managerDn("username")
                .managerPassword("password!")
                .and()
                .groupSearchFilter("(&(objectClass=user)(sAMAccountName=" + "username" + "))");

    }

    private Filter csrfHeaderFilter() {
        return new OncePerRequestFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request,
                    HttpServletResponse response, FilterChain filterChain)
                    throws ServletException, IOException {
                CsrfToken csrf = (CsrfToken) request
                        .getAttribute(CsrfToken.class.getName());
                if (csrf != null) {
                    Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                    String token = csrf.getToken();
                    if (cookie == null || token != null
                            && !token.equals(cookie.getValue())) {
                        cookie = new Cookie("XSRF-TOKEN", token);
                        cookie.setPath("/");
                        response.addCookie(cookie);
                        response.sendRedirect("/notAllowed");
                    }
                }
                filterChain.doFilter(request, response);
            }
        };
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }
}

      

        
        
        
      

    

My controller

    @RequestMapping(value = { "/test" }, method = RequestMethod.GET)
public @ResponseBody String retrieve() {
    System.out.println("line 1");
    System.out.println("line 2");
    return "hello";

}

@RequestMapping(value = { "/notAllowed" }, method = RequestMethod.GET)
public @ResponseBody HttpStatus login() {

    return HttpStatus.FORBIDDEN;

}

      

        
        
        
      

    

I am targeting:

I want to do ldap authentication . U username and password will come from browser , although I also tried with hardcoded username and password.

if the user is authentic , then the filter checks the authorization by checking the token .

if this is the first request , then a new token will be generated and sent. if not found , it will send HTTP Disabled status .

I have the following problems:

• when i run the first time from the browser it returns a ban, but it also outputs the lines "line 1 and line 2" in the console, although it does not return hi but it is forbidden.

• Are my htpSecurity and ldap settings ok ?.

• from the second request it always returns hi, I tried to open a new tab, new request, but it still works fine. If I restart the server , then only it generates the token and compare it with the cookie token. If two people use the same system (at different times).

• how exactly can I check for ldap authentication? I am using POSTMAN as a client.

If any information is missing from my end, please let me know. And I will be grateful for your answers.
