3. What is LDAP? (LIGHTWEIGHT DIRECTORY ACCESS PROTOCOL)
Lightweight Directory Access Protocol (LDAP) is a standard application protocol for accessing and managing a directory service. It is
supported by most vendor directory services, including Active Directory (AD), and facilitates the sharing of information on users, systems,
networks, services, and applications with applications and services that need it.
The concept of LDAP is its information model, which handles with information stored in directories and the hierarchical structuring of
information. The information model revolves around an entry (user or group, organization …) , which is a collection of fields that are
attributed to a user with type and value. Entries are organized in a tree structure called the directory information tree. The entries are
composed around real world concepts, organization, people and objects. Attribute types are associated with syntax defining allowed
information. An attribute in its singularity can enclose multiple values/fields init.
