I'm trying to search in ldapjs using method 'search', but it is not working for me.

Here is response from terminal :

        });

    let opts = {

    client_admin.search('dc=example,dc=', opts, (err, res) => {
        res.on('searchEntry', (entry) => {

        res.on('searchReference', (referral) => {

        res.on('end', (result) => {

};

Tried to add new user, successfully. But i didn't got any response. How can i get any data using this method?

• javascript
• ldap
• ldapjs

• So which is it, are you searching for users or adding? Which part of your code is failing? Expected behaviour and actual behaviour? – Arg0n Commented Mar 21, 2017 at 12:52
• I am searching. I tried to add new user in ldap, it was successfully . But when i trying to search , it's wrong – Никита Урсу Commented Mar 21, 2017 at 12:55

At the very first step after creating the LDAP client, you need to do the binding using the username and password. So, I guess the username you have used is not correct.

This works for me: (The values shown here are of course different):

var ldap = require('ldapjs');
var tlsOptions = {
    host: 'example.',
    port: '636',
    ca: [fs.readFileSync('/path/to/cert.pem')]
};
var client = ldap.createClient({
    url: 'ldaps://example.:636',
    tlsOptions: tlsOptions
});

client.bind(username, password, function (err) {
    if (err) {
        console.log('Error occurred while binding');
    } else {
        var base = 'cn=admin,dc=example,dc=';
        var search_options = {
            scope: 'sub',
            filter: '(&(objectClass=*)(CN=' + username + '))',
            attrs: 'memberOf'
        };
        client.search(base, search_options, function (err, res) {
            if (err) {
                console.log('Error occurred while ldap search');
            } else {
                res.on('searchEntry', function (entry) {
                    console.log('Entry', JSON.stringify(entry.object));
                });
                res.on('searchReference', function (referral) {
                    console.log('Referral', referral);
                });
                res.on('error', function (err) {
                    console.log('Error is', err);
                });
                res.on('end', function (result) {
                    console.log('Result is', result);
                });
            }
        });
    }
});

//here is how I get the result: see the entries variable

// SEARCH OPTIONS

let searchAllUsersOptions = {
    attributes: [
      "dc",
      "createTimestamp",
      "modifyTimestamp",
      "pwdPolicySubentry"
    ],
    scope: "sub",
    filter: "(objectClass=person)"
  };

  // SET DN
  let searchAllUsersDN = "dc=example,dc=";

  //THIS IS HOW YOU GET THE RESULTS OUT OF THE CLIENT SEARC
  let entries = [];

  client.search(searchAllUsersDN, searchAllUsersOptions, (err, res) => {

    if (err) return reject(err);

    res.on('searchEntry', function (entry) {
      var r = entry.object;
      entries.push(r);
      //console.log('search find one user');
      //console.log(entries); 
    });

    res.on('error', function (err) {
      reject(err);
    });

    res.on('end', function (result) {
      //resolve(entries);
    });

  });


  router.get('/', (req, res) => {
    res.send(JSON.stringify(entries)  );
  });

So is there anyway to search whole LDAP three without binding user with login and password? code below returns error: Operations Error in console.

let searchAllUsersOptions = {
    attributes: [
      "dc",
      "createTimestamp",
      "modifyTimestamp",
      "pwdPolicySubentry"
    ],
    scope: "sub",
    filter: "(objectClass=person)"
  };

  // SET DN
  let searchAllUsersDN = "dc=example,dc=";

  //THIS IS HOW YOU GET THE RESULTS OUT OF THE CLIENT SEARC
  let entries = [];

  client.search(searchAllUsersDN, searchAllUsersOptions, (err, res) => {

    if (err) return reject(err);

    res.on('searchEntry', function (entry) {
      var r = entry.object;
      entries.push(r);
      //console.log('search find one user');
      //console.log(entries); 
    });

    res.on('error', function (err) {
      reject(err);
    });

    res.on('end', function (result) {
      //resolve(entries);
    });

  });


  router.get('/', (req, res) => {
    res.send(JSON.stringify(entries)  );
  });
