Modern Authentication with Azure Active Directory for Web Applications (Developer Reference)

Vittorio is a well-known expert in the field of web application authentication with Azure Active Directory (AAD) and Active Directory Federated Services (ADFS). That expertise comes shining through in this book, which is a great combination of history, theory, and hands-on exercises. This book meets a serious need in the community for better understanding of Open Authentication (OAuth) and OpenID Connect. In my opinion, the general lack of understanding within some corners of the development community is preventing organizations from effectively moving to the cloud because their development teams do not understand how to make the transition with mission-critical applications. I routinely see code intended for use with Windows authentication being applied to web applications, and developers can't figure out what's wrong. If you cannot adequately explain OAuth and OpenID Connect, if you can't implement these technologies in both server-side and client-side apps, then get this book and read it cover to cover. This book has the information you need to be relevant in a cloud world.

Just finished reading the book! An awesome read! Historical throwback into the evolution of identity solutions/services is great, the depth and examples/gotchas provided throughout are spot on. Even though the book was published in 2016 it is a recommended read for Azure Active Directory and developers implementing various identity flows/scenarios in web apps! Well done, Author!

This book does a great job explaining the foundations of Azure Application models and the concepts of modern auth in that context. I’ve learned a lot more from this book than I did reading docs

Good book arrived quickly. Thanks!

This book is ostensibly about Azure AD, and the code samples are all in C#, but it could have just as accurately been entitled "Everything a Modern Developer Needs to Know About Claims-based Authentication, OAuth 2.0, Open ID Connect, and Related Technologies." The conceptual overview material is fantastic - I finally feel like I "get" the details of OAuth2! Highly recommended.

Tremendously helpful book that covers information about some of the inner workings of authentication with Azure AD that are hard to come by. Also helpful background on some of the why's of the protocols and implementation choices in Azure AD. I'd recommend this book to anyone building apps (or even just administering) with Azure AD and wants to really understand what is going on.

Hard to use to do anything practical. Simultaneously covers everything - every platform, every application type all mish-mashed together. Nobody sits down to write five different applications at the same time while they are learning.

This book was well written and clearly lays out the structure of the various standards as well as outlining the various ways that authentication systems are built and used. Chapter Two clearly defines all the identity systems and how they have been used and how WS-* morphed out of usage except in government areas such as CJIS. The examples demonstrate how OWIN plays within web applications and Azure.

From my point of view working with cloud identity providers is a tricky task which requires you to have an in-depth understanding of the underlying protocols. The cookbook examples make things look simple. However in the real world things become intricate particularly when you start interacting with third-party cloud service providers. Being a hands-on development book the author provides essential details on OAuth 2.0 and Open ID connect so that you are not forced to resort to the specifications. In the one or other case I read parts of the specifications however the book is pretty much self-contained and gives you everything you need in order to be up and running with Azure AD.

After reviewing a lot of online material including Pluralsight courses, I finally realised that I didn't understand enough about how to use ADAL with Azure AD. I found this book by Vittorio which I decided to invest my time in reading. The book is well written and easy to read. Having read it and implemented the examples, I have a much better understanding and feel like I have 'climbed over a mountain' and now can get on with writing the apps that I want.

Its very a very well explained and in-depth discourse on AAD authentication. Very informative and recommended

The go to resource for using Azure AD inside your Web Apps by the man! bought is as a Kindle book but wish I'd bought a hard copy. I may even have to go back and buy one

Excellent book covering a complex subject. The author explains concepts really well in an easy to follow way. Highly recommended.
