More than just the most comprehensive book on AD
Format: Paperback
I have been working with Active Directory since it was released in 2000 and even before that if you count its predecessor Exchange's directory. I can confidently say that this is the most comprehensive book on Active Directory that I have ever read. Of course there are all of the basics like designing AD structures, migrations to AD 2022, management of objects and group policies but then all of the AD services are also covered in-depth like DNS, DS, LDS, FS, RMS and CS. Furthermore this book tackles trusts, database maintenance and backup and recovery.
While not a book about Azure AD, there is a ton of information about Azure AD. The author takes the time and effort to compare AD with Azure AD and there are hundreds of references to Azure AD in terms of building out hybrid AD environments, federated identity and notes about how things are done in Azure AD versus AD. The chapter on PowerShell demonstrates scripts for both AD and Azure AD.
Here is what I think makes this book special though, and it is how the entire context for the book is around security, identity and access management. Essentially this book can be viewed as a book on security, identity and access management that demonstrates how to practically implement those concepts in Active Directory and Azure AD. There is fantastic information that explains the concepts of identity and access management clearly and concisely and covers topics such as zero trust, privileged access management (PAM) and more. Then, these concepts are translated into how they are implemented in Active Directory. It's a great way to present the information as it provides real world context and clearly explains the purpose of Active Directory versus purely just describing technical features and functionality. This is the way all technical books should be written.

A great read for those who want in depth knowledge about MS Active Directory & related services
Format: Paperback
Reviewer: 20 yrs training and consulting experience with Windows Server, Exchange Server, Active Directory, all major hypervisors, and cloud services. Active Directory along with all the related services and features are complex and many faceted topics. Books showing step by step examples are easy to come by, although not very useful since there’s plenty of Microsoft online help with the same info. What’s more important is to understand the features and related services and how to use them properly and securely.
This book covers in great detail Active Directory and the related services and features. There’s also plenty of information and expertise from a security perspective. With the move to cloud services and more employees are working from home there’s a whole new level of security issues to contend with. This book contains lots of in-depth explanations that allow you to understand why certain features and services exist and how to use them. This extra depth and the author’s experience is what makes this book special.
I would recommend this book for IT Professionals that already have some AD knowledge and experience. My only qualification is that I occasionally found some of the explanations confusing even after reading them over a several times.
I would highly recommend this book for those who wish to understand, configure and design an AD infrastructure along with associated services including OU design, group policy, object management delegation, ADFS, Certificate Services, etc. Although the book is not about Azure AD it does cover some aspects including integrating with on-prem AD.

Detailed coverage of Active Directory
Format: Kindle
I spent several years very close to active directory but haven’t followed developments in recent years. I was interested in this book as a refresher on what’s new in the last 8-10 years – and it did not disappoint.
The chapter on Advanced AD Management with PowerShell does a great job providing some background, setting the stage for why we’d want to know this, and providing some brief descriptions of various cmdlets that might be needed. My last experience with PowerShell/Active Directory required the Quest module, so seeing these native cmdlets is a nice change.
The chapter on AD FS is very detailed, providing a history of the functionality, deployment topologies and considerations, as well as details on configuring the required components. This is a topic I was not familiar with before seeing this book, and it did a good job bringing me up to speed on the feature.
I have not made it all the way through this book, but the sections I have completed are very good. If you are looking for a thorough reference guide on the current state of Active Directory, you should check out this book.

The book for designing and deploying Active Directory in your Organization
Format: Paperback
If you purchased an earlier release of this book and was wondering if this one is worth getting, the answer is yes!! The biggest change is this edition thoroughly covers the latest and greatest, Windows Server 2022. It walks through security issues, the differences between this and previous versions of Windows Server and how to design and deploy a functional and secure Server 2022 Active Directory. I enjoyed reading through this book and highly recommend it!
