LDAP
LDAP (Lightweight Directory Access Protocol) is like a company's digital phone book and security system combined. It's a way to organize and manage information about employees, their permissions, and access rights across different computer systems. Think of it as a central database that helps verify "who is who" and "who can access what" in an organization. When companies say they use LDAP, they usually mean they have a structured way to manage user accounts, passwords, and access permissions across their entire network. It's similar to Active Directory (which is Microsoft's version of LDAP) or OpenLDAP (a free, open-source version).
