Ldapjs

'Build status'

ldapjs makes the LDAP protocol a first class citizen in Node.js.

Usage

For full docs, head on over to http://ldapjs.org.

var ldap = require('ldapjs');

var server = ldap.createServer();

server.search('dc=example', function(req, res, next) {
  var obj = {
    dn: req.dn.toString(),
    attributes: {
      objectclass: ['organization', 'top'],
          o: 'example'
    }
  };

  if (req.filter.matches(obj.attributes))
    res.send(obj);

  res.end();
});

server.listen(1389, function() {
  console.log('ldapjs listening at ' + server.url);
});

To run that, assuming you've got the OpenLDAP client on your system:

ldapsearch -H ldap://localhost:1389 -x -b dc=example objectclass=*

Installation

npm install ldapjs

Formatting objectGUID attribute value

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);
    });
  });
});

Note: for the sake of simplicity all checks and error handling was removed from the sample above.

The console output may be similar to the following (depending on the amount of users in the directory):

{a7667bb1-4aee-48ce-9d9d-a1193550deba}
{8d642ac8-14c6-4f27-ac5-94d39833da88}

Available formatting modes:

GUID_FORMAT_N
    N specifier, 32 digits:
    00000000000000000000000000000000
GUID_FORMAT_D
    D specifier, 32 digits separated by hypens:
    00000000-0000-0000-0000-000000000000
GUID_FORMAT_B
    B specifier, 32 digits separated by hyphens, enclosed in braces:
    {00000000-0000-0000-0000-000000000000}
GUID_FORMAT_P
    P speficier, 32 digits separated by hyphens, enclosed in parentheses:
    (00000000-0000-0000-0000-000000000000)
GUID_FORMAT_X
    X speficier, four hexadecimal values enclosed in braces,
    where the fourth value is a subset of eight hexadecimal values that is also enclosed in braces:
    {0x00000000,0x0000,0x0000,{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}}

Guid formatting is unobtrusive by default. You should explicitly define formatting mode in order to enable it.
