angular2 ldap authentication

Question

无论如何在ldap authentication中实施angular2？我正在尝试将我的网络应用程序迁移到Angular2，现在我完成了大部分用户界面部分，现在我离开了Authentication。我在过去的应用中使用了springboot ldap authentication，我使用userDN和密码连接到ldaps://example.host:636/。我正在寻找使用ldap进行身份验证的方法。我查看了这个link但未找到注册位置或提供我的ldap服务器详细信息，认为可供付费用户使用。请建议我为Angular2实现身份验证的最佳方法，无需任何其他额外费用。

EDITED

尝试使用ldapjs foud here，但收到编译错误...

我已安装ldapjs 1.0.1

我的LDAPClientComponent

const ldap = require('ldapjs');
const _ = require('underscore');
@Component({})
export class LdapClientComponent implements OnInit {

    username: string = 'my-username';
    mypassword: string = 'my-password';
    limit: number = 5000;
    ngOnInit() { this.auth();}      
    auth(){
        let ldapClient = ldap.createClient('ldap://example.org/'),
        search = _.clone(this.ldapConfig.search);

        if (search.filter) {
            search.filter = search.filter.replace('{{username}}', this.username);
        }
        ldapClient.search(this.ldapConfig.base, search, function(err, res) {
            if (err) { console.log(err); } 
            else {
             res.on('searchEntry', function(entry) {
                this.dapCompare(ldapClient, entry.dn);
             });
            }
        });

    }

    ldapCompare(ldapClient, dn){
        ldapClient.compare(dn, 'userPassword', this.mypassword, function(err, pass ) {
            if (err) {console.log(err);} 
            else if (!pass) {
                console.log('Not Authorized');
            } else {
                console.log('OK!');
            }
        });
    }

    ldapConfig = {
        "server": {
            "url": "ldap://example.org/"
        },
        "base": "dc=example,dc=org",
        "search": {
            "filter": "(uid={{username}})",
            "scope": "sub"
        }
    }
