Spring boot Active Directory/LDAP connection

I already connect with AD from spring boot for login purposes but i can not mak searches. My configuration is

@Configuration
public class LdapTemplateConfig {

    @Bean
    public LdapTemplate ldapTemplate() {
        LdapTemplate ldapTemplate = new LdapTemplate(ldapContextSource());
        return ldapTemplate;
    }

    @Bean
    public LdapContextSource ldapContextSource() {

        String url = "ldap://127.0.0.1:389";
        String base = "DC=demo1,DC=demo2,DC=demo3,DC=demo4";

        LdapContextSource ldapContextSource = new LdapContextSource();
        ldapContextSource.setUrl(url);
        ldapContextSource.setUserDn(
                "CN=User Name,OU=Common Users OU,OU=RDP enabled Users OU,OU=Operator Users OU,OU=Admin Users OU,DC=demo1,DC=demo2,DC=demo3,DC=demo4");
        ldapContextSource.setPassword("password");
    //  ldapContextSource.setReferral("follow");
        ldapContextSource.afterPropertiesSet();
        return ldapContextSource;
    }
}


@Service
public class LDAPServiceImpl {

    @Autowired
    private LdapTemplate ldapTemplate;

    public void getUserDetails(String userName) {
        if (null != ldapTemplate) {
            List<String> vals = ldapTemplate.search(query().where("objectclass").is("person"),
                    new AttributesMapper<String>() {
                        @Override
                        public String mapFromAttributes(Attributes attributes) throws NamingException {
                            return attributes.get("sAMAccountName").get().toString();
                        }
                    });
            for (String s : vals) {
                log.info("attr : " + s);
            }
        } else {
            log.info("Templates is null");
        }
    }
}

So, when i call the function getUserDetails() from controller it returns “Templates is null”

I solved the problem thanks all for your help

@Configuration
public class LdapTemplateConfig {

    private final Logger log = LoggerFactory.getLogger(LdapTemplateConfig.class);

    @Bean(name = "ldapTemplate")
    // @Scope("singleton")

        LdapTemplate ldapTemplate = new LdapTemplate(contextSource);
        return ldapTemplate;
    }

    @Bean(name = "contextSource")
    // @Scope("singleton")
    public LdapContextSource ldapContextSource() {

        String url = "ldap://127.0.0.1:389";
        String base = "DC=intranet,DC=demo,DC=com";

        if (isConfigurationValid(url, base)) {
            LdapContextSource ldapContextSource = new LdapContextSource();
            ldapContextSource.setUrl(url);
            ldapContextSource.setBase(base);
            ldapContextSource.setUserDn(

            ldapContextSource.setPassword("password");
            ldapContextSource.setReferral("follow");
            // lcs.setPooled(false);
            // lcs.setDirObjectFactory(DefaultDirObjectFactory.class);
            ldapContextSource.afterPropertiesSet();
            return ldapContextSource;
        }
        return null;
    }

    public boolean isConfigurationValid(String url, String base) {
        if ((url == null) || url.isEmpty() || (base == null) || base.isEmpty()) {
            log.error("Warning! Your LDAP server is not configured.");
            log.info("Did you configure your LDAP settings in your application.yml?");
            return false;

            }

            return user;
        }
    }

}

and into the controller i put

    @Autowired
    private LDAPServiceImpl lDAPServiceImpl;
com.ppc.ptol2.service.impl.User find = lDAPServiceImpl.getUserDetails("sgad");

as you can see the solution is working perfectly but needds some improvements
