Lightweight Directory Access Protocol (LDAP) is a protocol for managing access to a file and directory hierarchy from some centralized location. LDAP is mainly used for centralized authentication.
An LDAP server helps in controlling who has access to read and update information in the directory.
To install and configure LDAP, we need to first create an Ubuntu server. The current version for Ubuntu server installation media can be found here: http://www.ubuntu.com/download/server.
After downloading, follow the steps provided to install an Ubuntu server.
We need a second system with a desktop version of Ubuntu installed. This will be used to access your LDAP server through a web interface.
Once this is done, we can proceed with the installation of LDAP.
