Learn how to install and configure OpenLDAP server for centralized authentication in Ubuntu 16.04/18.04 and CentOS 7 in this helpful tutorial.
Lightweight Directory Access Protocol (LDAP in short) is an industry standard, lightweight, widely used set of protocols for accessing directory services. A directory service is a shared information infrastructure for accessing, managing, organizing, and updating everyday items and network resources, such as users, groups, devices, emails addresses, telephone numbers, volumes and many other objects.
The LDAP information model is based on entries. An entry in a LDAP directory represents a single unit or information and is uniquely identified by what is called a Distinguished Name (DN). Each of the entry’s attributes has a type and one or more values.
