Mastering Active Directory

By: Dishan Francis

Overview of this book

Active Directory is a centralized and standardized system that automates networked management of user data, security, and distributed resources and enables interoperation with other directories. If you are aware of Active Directory basics and want to gain expertise in it, this book is perfect for you. We will quickly go through the architecture and fundamentals of Active Directory and then dive deep into the core components, such as forests, domains, sites, trust relationships, OU, objects, attributes, DNS, and replication. We will then move on to AD schemas, global catalogs, LDAP, RODC, RMS, certificate authorities, group policies, and security best practices, which will help you gain a better understanding of objects and components and how they can be used effectively. We will also cover AD Domain Services and Federation Services for Windows Server 2016 and all their new features. Last but not least, you will learn how to manage your identity infrastructure for a hybrid-cloud setup. All this will help you design, plan, deploy, manage operations on, and troubleshoot your enterprise identity infrastructure in a secure, effective manner. Furthermore, I will guide you through automating administrative tasks using PowerShell cmdlets. Toward the end of the book, we will cover best practices and troubleshooting techniques that can be used to improve security and performance in an identity infrastructure.

How to plan Active Directory migrations

Active Directory migration from an older version to a new version is a common challenge for identity infrastructures. In some documents, this is called Active Directory upgrades, but I prefer to call it Active Directory migration. In this process, a new AD DS version will install in a new server or an existing server. Then the FSMO roles will migrate to the new domain controllers. Once it's completed, the older version of AD DS will be decommissioned. Afterwards, the domain and forest function level will be raised to match the new AD DS version. Even though each AD DS version has core functions that are the same, newer versions always have new features and enhancements which apply at domain or forest level. Therefore, it's more of a migration than an upgrade. The migration term is also used for migrating Active Directory objects...
