How To Convert Federated Domain To Managed Domain In Azure AD - Part One

In this article, we will see how to convert the Federated domain which is using the ADFS Authentication using against the On-premises Active Directory to Managed Authentication against Azure Active Directory(AAD).

In this article, we will see how to convert a federated domain which is using the ADFS Authentication against the on-premises Active Directory to Managed Authentication against Azure Active Directory(AAD). ADFS Authentication is a token-based authentication and it is very secured wherein it has some limitation as it requires a Web Application Proxy(WAP) set up to allow the users to get authenticated from the connected internet.

On the other hand, the Azure AD authentication is very fast and secured. It removes the dependency of On-premises.

To convert to a managed domain, we need to do the following tasks.

  1. Enable the Password sync using the AADConnect Agent Server
  2. Sync the Passwords of the users to the Azure AD using the Full Sync
  3. Convert the domain from Federated to Managed
