Configure Hybrid Windows Hello for Business: Directory Synchronization

Applies to

  • Windows 10, version 1703 or later
  • Hybrid deployment
  • Certificate trust

Directory Synchronization

In hybrid deployments, users register the public portion of their Windows Hello for Business credential with Azure. Azure AD Connect synchronizes the Windows Hello for Business public key to Active Directory.

The key-trust model needs Windows Server 2016 domain controllers, which configures the key registration permissions automatically; however, the certificate-trust model does not and requires you to add the permissions manually.

Important

If you already have a Windows Server 2016 domain controller in your domain, you can skip Configure Permissions for Key Synchronization.
