Setup PHP development environment width LDAP

I have created a system to authenticate LDAP from PHP before.

At that time, I created a development environment with Docker, so I'll make a note of how to set it up.

The environment I used is as follows.

• macOS Catalina 10.15.5
• Git
• Docker Desktop for Mac

How to setup

open a terminal and clone LAMP+OpenLDAP Dev Docker repository.

git clone https://github.com/ko31/lamp-dev-docker.git <your-project-name>

Create and start containers.

cd <my-project-name>
docker-compose up -d

Then, you can access your local website at http://localhost:8000
(The document root is the <your-project-name>/www/html directory.)

Try connecting to LDAP from PHP

To begin, make sure you have users connecting to your LDAP server.

Open phpLDAPadmin at http://localhost:8888 and click login.

In this container, the Login DN is cn=admin,dc=example,dc=com and the Password is password by default. Input it and click authenticate.

You can see that you were able to logged as an admin user.

Create <your-project-name>/www/html/connect.php and put the following:

<?php
// LDAP settings
const LDAP_HOST = "ldap-host";
const LDAP_PORT = 389;
const LDAP_DC = "dc=example,dc=com";
const LDAP_CN = "admin";
const LDAP_PASS = "password";

// Connect LDAP server.
$ldap_conn = ldap_connect(LDAP_HOST, LDAP_PORT);
if (!$ldap_conn) {
    exit('Could not connect to LDAP server.');
}

// Switch protocol to LDAPv3.
ldap_set_option($ldap_conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap_conn, LDAP_OPT_REFERRALS, 0);

// Bind to LDAP directory.
$ldap_dn = 'cn=' . LDAP_CN . ',' . LDAP_DC;
$ldap_bind = ldap_bind($ldap_conn, $ldap_dn ,LDAP_PASS);
if ($ldap_bind) {
    exit('LDAP bind successful..');
} else {
    exit('LDAP bind failed.');
}

You can confirm a successful connection at http://localhost:8000/connect.php

Have fun!👍
