Simple definition
Hybrid identity integrates on-premises directory identities with cloud authentication and access services.
Purpose and use
Hybrid identity connects identity management in an on-premises environment with cloud identity services.
How does it work?
Object synchronization and authentication are related but separate choices, such as password hash synchronization, pass-through authentication or federation.
Example and verification
To analyze a sign-in, identify the account source, authentication path and components that must be available at that moment.
Points to watch
Synchronizing a user does not automatically assign every application license or permission. Deletion and source changes also need control.
In short
Hybrid consistency requires clear ownership of objects, attributes and access mechanisms.
