What is the main function of Lightweight Directory Access Protocol (LDAP)?

The main function of Lightweight Directory Access Protocol (LDAP) is to provide a protocol for directory service communications. LDAP is designed to access and manage directory information over an IP network. This structured directory service allows for efficient querying and modification of directory entries, which typically contain user information, access controls, and organizational structures. LDAP serves as a means for various applications and services to communicate with directory services, allowing users and systems to authenticate and access resources securely.

By using LDAP, it becomes easier for organizations to manage user credentials and access permissions in a centralized manner, enhancing security and operational efficiency. The emphasis on directory service communication is why option B accurately captures the essence of what LDAP is intended for, distinguishing it from other options that pertain to different functionalities unrelated to directory access and management.
