Today I am writing this post here to bring to readers attention about the new ADFS 3.0
which comes as a part of Windows Server 2012 R2
and how we can utilize the new benefits of this Service by knowing its pros and cons and how to deploy the same in to our Organization and make use of it with Office 365.
Review my earlier blog post ADFS in O365 in a Nutshell
to understand the role of ADFS and its deployment considerations and see it in action with the provided references as a start.
Also read this Microsoft Knowledge base
article to know the Supported Scenarios for providing SSO with ADFS
Supported scenarios for using ADFS to setup single sign-on in Office 365
Check the below article for a quick preview of Single Sign-On for Office 365
Overview of single sign-on for Office 365
In comparison with other Identity management providers ADFS is the most common implementation for SSO with Office 365.
Organizations that already deployed ADFS either use ADFS 2.0 or ADFS 2.1 in their environment for SSO as this a known deployment method so far with office 365 and an essential prerequisite if you are going have a federated domain. You can provide same sign on experience with the new Dirsync Password hash
without having federated Identity, and for true SSO ADFS is the best option, Check my earlier blog post "ADFS Vs Password Hash
" to know the differences provided with references.
ADFS comes as a separate download earlier when Organizations made the deployment and serving millions of customers. As the Technology changes by time, now we no longer need to do a separate installation of ADFS as before and also other significant changes are made to the federation setup with the arrival of the latest Windows Server 2012 R2. Many Organizations already upgraded their environment to the latest Server platform and still some are in their evaluation stages, As everyone know that Windows Server 2012 R2 is a robust product that it predecessors most of of the IT Infrastructure is getting upgraded to this Version and already it marked it presence in most of the private and public cloud offerings.
Review the new ADFS changes here with TechNet: Active Directory Federation Services Overview
Lets get back to our topic ADFS 2.x based deployment had both internal ADFS servers and external ADFS proxy relies on the IIS, with this latest update it does not relies on IIS and also the ADFS proxy servers are now being replaced with the WAP ( Web Application proxy)
where we can eliminate the need of ADFS proxy servers and use the WAP to publish the ADFS URL to the internet using any of your traditional Reverse proxy system.
I reviewed the below Excellent post from our Microsoft Consultant Marius Solbakken Mellum
on his goodworkaround
blog where he explains about the above said information clearly along with other vital topics and visually shows us how to setup federation with ADFS 3.0 and also shows us how to publish the ADFS URL to internet using WAP, along with the O365 configuration steps post deployment.

Also, ensure that you have the latest Windows Azure Active Directory (WAAD) Module for Windows PowerShell
installed on your environment and then proceed with the Office 365 federation configuration as this is mandate and a prerequisite to make things work with ADFS 3.0, Refer the below post from our
on the same.

My Environment is not yet upgraded and soon it will be done and these post will be quite useful for me as well as you to evaluate the changes in the Lab domain and proceed with the production, hope will get additional information when I do that and share it with you soon.
Recently Microsoft team released a new update for Windows Server 2012 R2 which adds one more great feature to ADFS 3.0 wherein now users can be identified and authenticated to Microsoft Azure and O365 using a new attribute called " Alternate Login ID"
in a federated scenario. This adds real benefit for Organizations who are not using UPN same as E-mail address and also for Organizations who are not using publicly resolvable UPN. Refer the below TechNet article for more details, Currently we don't have any walk through available for this apart from this below TechNet article and soon we can expect Microsoft to update us more on this and will post the related content once I came across in mere future, watch out for updates in the below space...
Here is the Microsoft Knowledge base article published with the update details to install and get this feature.
