LDAP vs Keratin AuthN: What are the differences?

What is LDAP? A lightweight directory access protocol. It is a mature, flexible, and well supported standards-based mechanism for interacting with directory servers. It’s often used for authentication and storing information about users, groups, and applications, but an LDAP directory server is a fairly general-purpose data store and can be used in a wide variety of applications.

What is Keratin AuthN? Accounts and Auth Microservice in Go. AuthN manages a database of user accounts with sign-in credentials and related attributes. Your application frontend relies on AuthN for creating accounts, logging in, forgotten passwords, and session maintenance.

LDAP and Keratin AuthN can be categorized as "User Management and Authentication" tools.
