What are the difference between Managed and Federated domains in hybrid mode?

by XDK 11. October 2019 23:53

Explanation:

Managed domain is the normal domain in Azure AD and can be deployed either through "Password Hash Sync" or "Pass Through Authentication" with Single Sign On.

Federated domain is used for Active Directory Federation Services (ADFS). The federation trust will make sure that the accounts in the on-premises Active Directory are trusted for use with the accounts in Azure AD with Single Sign On.

Deployed through WS-Fed and WS-Trust:
WS-Fed: This protocol is required to join a device to Azure AD.
WS-Trust: This protocol is required to sign in to an Azure AD joined device.
