Installing OpenLDAP on Ubuntu 18.04

OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol (LDAP) for managing and accessing directory services. It provides a centralized database for storing and managing information about users, groups, and other directory objects.

Step 1: Update the System

sudo apt update
sudo apt upgrade

Step 2: Install OpenLDAP

sudo apt install slapd ldap-utils

Step 3: Configure slapd

The installation process will prompt you to configure slapd. You will need to provide a few details such as the organization name, the administrator password, and the database backend.

sudo dpkg-reconfigure slapd

Step 4: Test the Installation

You can test the installation by searching for the root DSE (Directory Server Entry) using the ldapsearch command.

ldapsearch -x -b "" -s base "(objectclass=*)"

Step 5: Secure OpenLDAP

By default, OpenLDAP does not enforce any security. To secure OpenLDAP, you can enable SSL/TLS encryption and configure access control rules.

Conclusion

OpenLDAP is a powerful tool for managing directory services. By following the above steps, you can install and set up OpenLDAP on your Ubuntu 18.04 system.
