How to Setup Apache Authentication using LDAP Active Directory. In this post, we introduce Apache, its features, advantages and after we talk you through step by step process of how to setup Apache authentication using LDAP active directory.
What is Apache?
First of all, Apache is a free, open source web server software widely used to host websites on the internet. Developed and maintained by a community driven software organization Apache Foundation.
One of the key features of Apache is its support for multiple protocols, including HTTP, HTTPS, and FTP. Also, it has built in support for PHP, a popular programming language for developing dynamic websites. What is more, Apache also has several security features, such as support for SSL/TLS encryption, password protection, and access control.
Additionally, Apache is a reverse proxy server, load balancer, and HTTP cache. Often used in combination with other software, such as the MySQL database and the PHP programming language, to build powerful and dynamic websites.
Overall, Apache is a reliable and widely used web server that is suitable for a wide range of websites and applications. Specifically, active community of developers make it an attractive choice for many organizations and individuals looking to host websites on the internet.

- Stable and Reliable: Apache is known for its stability and reliability. It handles a large number of requests concurrently and can recover quickly from errors or crashes.
Now, we are at the main part of the article How to Setup Apache Authentication using LDAP Active Directory. Please follow up.
How to Setup Apache Authentication using LDAP Active Directory
Prerequisites
Install Apache Web Server
apt-get install apache2 apache2-utils -y
After installing the Apache package, start the Apache service and enable it to start after the system reboot.
systemctl start apache2
systemctl enable apache2
Now, verify the Apache version using the following command.
apache2ctl -V
You should get the Apache version in the following output.
Server version: Apache/2.4.52 (Ubuntu)
Server built: 2022-09-30T04:09:50
Server's Module Magic Number: 20120211:121
Server loaded: APR 1.7.0, APR-UTIL 1.6.1
Compiled using: APR 1.7.0, APR-UTIL 1.6.1
Architecture: 64-bit
At this point, the Apache web server is installed and configured on your system. You can now proceed to create a sample file to host on the Apache web server.
Create a Simple HTML Page
Next, you need to create a simple test page to host on your web server. First, create a directory to host a website with the following command.
mkdir /var/www/html/ldap
After that, create an index.html page using the following command.
nano /var/www/html/ldap/index.html
Add the following HTML code:
<html>
<body>
<div style="width: 100%; font-size: 50px; font-weight: bold; text-align: center;">
Congratulations! Apache web server is now configured with LDAP Active Directory Authentication.
</div>
<script>class RocketElementorAnimation{constructor(){this.deviceMode=document.createElement("span"),this.deviceMode.id="elementor-device-mode-wpr",this.deviceMode.setAttribute("class","elementor-screen-only"),document.body.appendChild(this.deviceMode)}_detectAnimations(){let t=getComputedStyle(this.deviceMode,":after").content.replace(/"/g,"");this.animationSettingKeys=this._listAnimationSettingsKeys(t),document.querySelectorAll(".elementor-invisible[data-settings]").forEach(t=>{const e=t.getBoundingClientRect();if(e.bottom>=0&&e.top<=window.innerHeight)try{this._animateElement(t)}catch(t){}})}_animateElement(t){const e=JSON.parse(t.dataset.settings),i=e._animation_delay||e.animation_delay||0,n=e[this.animationSettingKeys.find(t=>e[t])];if("none"===n)return void t.classList.remove("elementor-invisible");t.classList.remove(n),this.currentAnimation&&t.classList.remove(this.currentAnimation),this.currentAnimation=n;let s=setTimeout(()=>{t.classList.remove("elementor-invisible"),t.classList.add("animated",n),this._removeAnimationSettings(t,e)},i);window.addEventListener("rocket-startLoading",function(){clearTimeout(s)})}_listAnimationSettingsKeys(t="mobile"){const e=[""];switch(t){case"mobile":e.unshift("_mobile");case"tablet":e.unshift("_tablet");case"desktop":e.unshift("_desktop")}const i=[];return["animation","_animation"].forEach(t=>{e.forEach(e=>{i.push(t+e)})}),i}_removeAnimationSettings(t,e){this._listAnimationSettingsKeys().forEach(t=>delete e[t]),t.dataset.settings=JSON.stringify(e)}static run(){const t=new RocketElementorAnimation;requestAnimationFrame(t._detectAnimations.bind(t))}}document.addEventListener("DOMContentLoaded",RocketElementorAnimation.run);</script></body>
</html>
Save and close the file then change the ownership and permission of your website directory.
chown -R www-data:www-data /var/www/html/ldap
chmod -R 755 /var/www/html/ldap
Once you are done, you proceed to configure the Apache web server.
Configure Apache for Active Directory LDAP Authentication
Now, you will need to create an Apache virtual host configuration file and define your LDAP Active directory authentication.
You can create it with the following command.
nano /etc/apache2/sites-available/ldap.conf
Add the following configurations:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName ldap.example.com
DocumentRoot /var/www/html/ldap
DirectoryIndex index.html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory "/var/www/html/ldap">
Options Indexes FollowSymlinks
AuthType Basic
AuthName "Apache LDAP authentication"
AuthBasicAuthoritative Off
AuthBasicProvider ldap
AuthLDAPURL "ldap://ldap-server-ip/CN=Users,DC=example,DC=local?sAMAccountName?sub?(objectClass=*)"
AuthLDAPBindDN "bind@example.local"
AuthLDAPBindPassword securepassword..
Require valid-user
</Directory>
</VirtualHost>
Save and close the file when you are done. Then, verify the Apache for any configuration error with the following command.
apachectl -t
You should get the following output:
Syntax OK
Next, enable the LDAP module with the following command.
a2enmod authnz_ldap
After that, activate the Apache virtual host configuration file using the following command.
a2ensite ldap.conf
Finally, restart the Apache service to apply the configuration changes.
systemctl restart apache2
Verify Apache LDAP Authentication
At this point, the Apache web server is configured with LDAP Active directory authentication. Now, it’s time to test it. Open your web browser and access the Apache sample page using the URL http://ldap.example.com. You will be asked to provide your LDAP username and password as shown below.
Provide your LDAP username, password and click on the Sign In button. Once you are successfully authenticated with LDAP, you should see your sample HTML page on the following screen.
