ADFS in O365 in a Nutshell

When it comes to O365 deployment Identity and Access Management plays a vital role and once the Organization decided for moving it's resources to cloud and also wants to have a seamless sign in experience on both On premise and Cloud which we termed as Single Sign On (SSO) , then your Active Directory Federation Services (ADFS) is the backbone for making this possible, I already wrote a post on O365 SSO Content road map where all the required components for establishing a successful SSO setup with O365 is written and explained by Microsoft and this is second one in the series which covers some vital part over ADFS in detail and puts things in a nutshell.

As usual I am not going to write the whole story as these topics were widely covered by Microsoft and Renowned MVPs and Experts in an excellent manner and I am pointing you today to a high level Technical documentation and also to a presentation on Exchange 2013 Hybrid deployment which typically explains about what you need to prepare yourself for a successful O365 Hybrid environment and most vital part it will clearly explain you each aspect and also shows you how the authentication happens with ADFS, while your clients are attempting to connect to O365 inclusive of Active and Passive authentication mechanisms and other vital components like Dirsync etc. which gives you a rich experience on understanding how authentication works in O365 with ADFS.
