Lightweight Directory Access Protocol (LDAP) sounds much more complicated than it actually is. LDAP is a software protocol that is commonly used to interact with servers that store user information, including digital certificates. Using LDAP allows verified users to locate pertinent resources such as organizations, individuals, files, and devices within a network. This network can exist either over the internet or as an intranet specific to your company, building, or office. While connections to a certain LDAP can be unencrypted, especially ones that do not exist on the internet, it is recommended to encrypt access to the service using transport layer security (TLS) or secure sockets layer (SSL).
LDAP can be used in dozens of scenarios as an easy way to access information about something within the company. For example, if you need to update an employee’s security clearance or check their office or computer number, you can use LDAP to pull all of their information at once. It’s a simple, time-saving measure that makes doing business just a bit easier.
