我正在创建一个登录身份验证页面,用户会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]
或
[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?
更新
以下是我想出的解决方案,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');}});
}

在这种情况下,您需要ldapClient
而不是ldapServer
,这是来自官方doc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。
以下是对您的更新的修改:
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,所以我收到了以下错误:
error: 1__ldap://my.domain.com/,OU=Employees,OU=Accounts,DC=my,DC=domain,DC=com closed
client disconnected

建议
1。请勿使用ldapauth-fork(巨大的挂起问题,如果我们遇到多个请求,则一段时间后库将变得无响应且不返回任何内容。)
2。不要使用passport-ldapauth(内部调用ldapauth-fork)
我们可以使用ldapjs,它易于实现,并且基于事件驱动方法。
下面的nodejs代码说明了ldap身份验证和搜索的完整解决方案。
JS代码
const ldap = require('ldapjs');
let client
// unbind after completion of process
function closeConnection() {
console.log('closeConnection')
client.unbind(err => {
console.log('unbind error', err)
});
}
function search() {
const searchOptions = {
filter: '(uid=yourSearchText)', // search text
scope: 'sub'
};
return new Promise((resolve, reject) => {
client.search('ou=consultants,' + 'ou="Your OU",ou=yourOu,dc=yourDc,dc=com', searchOptions, (err, res) => {
res.on('searchEntry', entry => {
console.log('searchEntry', entry.object);
resolve(entry.object)
});
res.on('searchReference', referral => {
console.log('referral: ' + referral.uris.join());
resolve(referral.uris.join())
});
res.on('error', err => {
console.error('search error: ' + err.message);
reject(err)
});
res.on('end', result => {
console.log('If not found', result);
reject({ message:'User not found'})
});
});
})
}
function authenticate() {
const server = 'ldap server ip';
client = ldap.createClient({
url: `ldap://${server}`
});
return new Promise((resolve, reject) => {
client.bind('cn=yourcn,dc=yourdc,dc=com', 'sortedSolutions', err => {
if (err) {
reject(err)
}
resolve('Authenticated successfully')
});
})
}
function start(req, res) {
let searchResponseData
authenticate()
.then(authenticateResponse => {
console.log('authenticateResponse', authenticateResponse)
return search()
})
.then(searchResponse => {
console.log('searchResponsesearchResponse', searchResponse)
searchResponseData = searchResponse
return closeConnection()
})
.then(closeConnectionResponse => {
console.log('ldap connection closed', closeConnectionResponse)
res.status(200).send(searchResponseData)
})
.catch(error => {
console.log('catch error', error)
res.status(400).send(error)
})
}
module.exports.start = start
//我们可以使用未经身份验证的相同代码,只需传递''来绑定函数client.bind('','',err => {//与上面相同})
