Query LDAP Objects as a MySQL Database in Node.js

Execute MySQL queries against LDAP objects from Node.js.

You can use the CData Cloud Hub to query LDAP objects through a MySQL interface. Follow the procedure below to create a virtual database for LDAP in the Cloud Hub and start querying using Node.js.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for LDAP, allowing you to easily query live LDAP objects in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to LDAP, leveraging server-side processing to quickly return LDAP objects.

Create a Virtual MySQL Database for LDAP Objects

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "LDAP" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to LDAP.

    To establish a connection, the following properties under the Authentication section must be provided:

    • Valid User and Password credentials (e.g., Domain\BobF or cn=Bob F,ou=Employees,dc=Domain).
    • Server information, including the IP or host name of the Server, as well as the Port.
    • BaseDN: This will limit the scope of LDAP searches to the height of the distinguished name provided.

      Note: Specifying a narrow BaseDN may greatly increase performance; for example, cn=users,dc=domain will only return results contained within cn=users and its children.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to LDAP objects from any MySQL client.

Query LDAP from Node.js

The following example shows how to define a connection and execute queries to LDAP with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for LDAP (ldapdb)

Connect to LDAP objects and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'ldapdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM User', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
