Mastering Active Directory. - Second Edition

By: Dishan Francis

Overview of this book

Active Directory (AD) is a centralized and standardized system that automates networked management of user data, security, and distributed resources and enables inter-operation with other directories. This book will first help you brush up on the AD architecture and fundamentals, before guiding you through core components, such as sites, trust relationships, objects, and attributes. You will then explore AD schemas, LDAP, RMS, and security best practices to understand objects and components and how they can be used effectively. Next, the book will provide extensive coverage of AD Domain Services and Federation Services for Windows Server 2016, and help you explore their new features. Furthermore, you will learn to manage your identity infrastructure for a hybrid cloud setup. All this will help you design, plan, deploy, manage operations, and troubleshoot your enterprise identity infrastructure in a secure and effective manner. You’ll later discover Azure AD Module, and learn to automate administrative tasks using PowerShell cmdlets. All along, this updated second edition will cover content based on the latest version of Active Directory, PowerShell 5.1 and LDAP. By the end of this book, you’ll be well versed with best practices and troubleshooting techniques for improving security and performance in identity infrastructures.

  • Active Directory upgrades: When the infrastructure needs to be upgraded from one Active Directory version to another, first we need to introduce the new domain controllers to the existing infrastructure and then move the FSMO roles. After that, the domain controllers that run older versions can decommissioned, and then we can increase the forest and domain functional levels to the latest (Windows server 2016).
  • Active Directory logical and physical topology: When installing the first domain controller in the infrastructure, it will automatically hold all five FSMO roles. But, based on the Active Directory topology design, the roles...
