Introduction
LDAP stands for Lightweight Directory Access Protocol which is an industry-standard application protocol for maintaining and accessing directory information services over IP networks. Directory information services match resources’ information to their respective IP addresses. LDAP’s role is to store emails, accounts, and passwords in a central location, and some applications will use this data for authentication.
