ADFS on Azure

Azure Active Directory and thus any relying party on that service (such as Office 365) has two different modes for (your) custom domains that are added to it. Managed and Federated. Managed means that the authentication happens against the Azure Active Directory. The password (-hashes) of the user accounts are in Azure AD and no connection to any (on-premises) Active Directory Domain is made.

Managed domains have the advantage that you don’t require any additional infrastructure, and setting up the identities for logging on to Office 365 for example, is fairly easy. However, it does not support any Single-Sign-On which most companies do want. That is why AAD also supports Federated domains, in this case the authentication for a user happens against the corporate (on-premises) Active Directory through a service called ADFS (Active Directory Federation Services). More information on federated versus managed can be found on the Kloud blog (https://blog.kloud.com.au/2013/06/05/office-365-to-federate-or-not-to-federate-that-is-the-question/)

In this article we are going to take a look at how the federation service can be hosted in Azure (and possibly also on-premises) and what the architectures might look like.
