What Is The Difference Between LDAP And Single Sign-On?
Security Boulevard, Tuesday, December 16th, 2025
Alright, let's dive into this whole LDAP vs. SSO thing, shall we? It's kinda like trying to explain the difference between a car engine and the entire car - related, but definitely not the same. So, what's the deal?
We're drowning in apps and services, right? Managing who gets into what, and safely, is a huge headache for IT teams. You need some solid ways to make sure only the right people are accessing sensitive stuff, and that's where authentication steps in. Think about it - a hospital needs to protect patient records, and a bank needs to keep your money safe, not to mention retailers trying to prevent fraud. It's a jungle out there!
Okay, so, LDAP? It's basically a way to organize and look up user info, like a digital phonebook. Now, SSO is more like a key that unlocks all your doors at once. You log in once, and boom, you're in all your apps. This article? We're gonna explain how these two work, and why you might use one over the other (Single Sign-On: The Difference Between ADFS vs. LDAP | Okta). First, we'll dig a little deeper into exactly what LDAP is all about, then we'll explore SSO, and finally, we'll compare them.
