Kerberos Delegation Concepts

Kerberos delegation lets a service prove it is acting on a user's behalf when it calls a second service, and Active Directory implements that idea three different ways. This lesson builds the shared mental model behind unconstrained, constrained, and resource-based constrained delegation so you understand why each one exists before studying how attackers abuse them.
