            LdapQuery query;
            LdapTemplate ldapTemplate = ldapConf.ldapTemplate();
            if (ldapConf.getSearchBase().isEmpty()) {
                System.out.println("searchbase empty");
                query = query().where(env.getProperty("retouch.ldap.searchKeyword")).isPresent();
            } else
                query = query().base(ldapConf.getSearchBase()).where(env.getProperty("retouch.ldap.searchKeyword")).isPresent();
            List<String> result = ldapTemplate.search(query, new AttributesMapper<String>() {
                public String mapFromAttributes(Attributes attrs) throws NamingException, javax.naming.NamingException {

                    for (Enumeration vals = attrs.get("distinguishedName").getAll(); vals.hasMoreElements();) {
                        String userName = (String) vals.nextElement();
                        if (userName.contains(username)) {
                            return (String) attrs.get("distinguishedName").get();
                        }
                    }

                    return null;
                }
            });

            while (result.remove(null)) {
            }
            return result;
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e, e);
            throw e;
        }
    }

I totally misunderstood ldap search mechanism. My ldap query was also wrong

query = query().where(env.getProperty("ldap.searchKeyword")).isPresent();

instead of isPresent() I should have used is(username) so I can directly get the user that I want. Also I was trying to get user DN in my code. Instead of new AttributesMapper<String>() , new ContextMapper<String>() provide the DN
