Ldapjs (Hotfixed for Node 0.12.x)

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

Notice:

This is a hotfixed version for Node 0.12.x based on v0.7.1. If there is a newer release of ldapjs i recommend trying that one. This is a drop-in replacement. Just require ldapjs-hotfix instead of ldapjs in your code and package.json.

Change made:

-  var closeSocket = (opts.secure ? socket.socket : socket);
+  var closeSocket = socket.socket || socket;

Usage

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

var ldap = require('ldapjs-hotfix');

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-hotfix

Formatting objectGUID attribute value

var ldap = require('ldapjs-hotfix');

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.
