节点JS LDAP身份验证用户

Question

我正在创建一个登录身份验证页面,用户将在其中输入活动目录用户名和密码,并使用NodeJS我会检查它是否有效,但我一直在

[Error: LDAP Error Bad search filter]

要么

[Error: Search returned != 1 results]

当我尝试搜索用户名和密码时,我的代码如下:

我正在使用:https://github.com/jeremycx/node-LDAP,假设用户输入了hhill的用户名

    var ldap = require('LDAP');
    var ldapServer = new ldap({ uri: 'ldap://batman.lan', version: 3});

    ldapServer.open(function(error) {
        if(error) {
           throw new Error('Cant not connect');
        } else {
            console.log('---- connected to ldap ----');

            username = '(cn='+username+')';
            ldapServer.findandbind({
                base: 'ou=users,ou=compton,dc=batman,dc=lan',
                filter: username,
                password: password
            }, function(error, data) {
                if(error){
                    console.log(error);
                } else {
                    console.log('---- verified user ----');
                }
            });
        }
    });

有没有人对我做错了什么有任何建议？

UPDATE

以下是我提出的解决方案,如果有人需要它,请在下面的答案的帮助下

    var username = request.param('username');
    var password = request.param('password');

    var ldap = require('ldapjs');
    ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;
    var client = ldap.createClient({
          url: 'ldap://batman.com/cn='+username+', ou=users, ou=compton, dc=batman, dc=com',
          timeout: 5000,
          connectTimeout: 10000
    });
    var opts = {
      filter: '(&(objectclass=user)(samaccountname='+username+'))',
      scope: 'sub',
      attributes: ['objectGUID']
    };

    console.log('--- going to try to connect user ---');

    try {
        client.bind(username, password, function (error) {
            if(error){
                console.log(error.message);
                client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
            } else {
                console.log('connected');
                client.search('ou=users, ou=compton, dc=batman, dc=com', opts, function(error, search) {
                    console.log('Searching.....');

                    search.on('searchEntry', function(entry) {
                        if(entry.object){
                            console.log('entry: %j ' + JSON.stringify(entry.object));
                        }
                    });

                    search.on('error', function(error) {
                        console.error('error: ' + error.message);
                    });

                    client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
                });
            }
        });
    } catch(error){
        console.log(error);
        client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
    }

Answer 1

在这种情况下,您需要ldapClient而不是ldapServer,这是官方文档中的示例代码:

var ldap = require('ldapjs');

ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;

var client = ldap.createClient({
  url: 'ldap://127.0.0.1/CN=test,OU=Development,DC=Home'
});

var opts = {
  filter: '(objectclass=user)',
  scope: 'sub',
  attributes: ['objectGUID']
};

client.bind('username', 'password', function (err) {
  client.search('CN=test,OU=Development,DC=Home', opts, function (err, search) {
    search.on('searchEntry', function (entry) {
      var user = entry.object;
      console.log(user.objectGUID);
    });
  });
});

@Sukh感谢您发布UPDATE解决方案; 但是,您在UPDATE中发布的代码存在问题.虽然它适用于简单的情况,但对于较大的查询,您会发现在输出结果之前您已取消绑定.我的解决方案是将你的unbinds移动到search.on函数中.

这是您的更新的编辑:

var ldap = require('ldapjs');
ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;
var client = ldap.createClient({
      url: 'ldap://batman.com/cn='+username+', ou=users, ou=compton, dc=batman, dc=com',
      timeout: 5000,
      connectTimeout: 10000
});
var opts = {
  filter: '(&(objectclass=user)(samaccountname='+username+'))',
  scope: 'sub',
  //attributes: ['objectGUID']
  // This attribute list is what broke your solution
  attributes: ['objectGUID','sAMAccountName','cn','mail','manager','memberOf']
};

console.log('--- going to try to connect user ---');

try {
    client.bind(username, password, function (error) {
        if(error){
            console.log(error.message);
            client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
        } else {
            console.log('connected');
            client.search('ou=users, ou=compton, dc=batman, dc=com', opts, function(error, search) {
                console.log('Searching.....');

                search.on('searchEntry', function(entry) {
                    if(entry.object){
                        console.log('entry: %j ' + JSON.stringify(entry.object));
                    }
                    client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
                });

                search.on('error', function(error) {
                    console.error('error: ' + error.message);
                    client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
                });

                // don't do this here
                //client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
            });
        }
    });
} catch(error){
    console.log(error);
    client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
}

至少这是我在使用Active Directory搜索解决方案时发现的.memberOf在我的用例中返回了很多条目,并且unbinds过早地完成了,所以我收到以下错误:

error: 1__ldap://my.domain.com/,OU=Employees,OU=Accounts,DC=my,DC=domain,DC=com closed
client disconnected
