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.

Even if you do not have on-premises AD integration with Azure AD, if you are using cloud applications such as Office 365, Dynamic CRM, or applications from the Azure marketplace (most of them), you are already using Azure AD in the backend.

There are three main ways which we can handle identities in cloud-only or hybrid environments:

  • Windows AD only: It's still a great tool. If you'd still like to manage organization identities only using on-premises solutions, it can be done using one of the following topologies:
    • Use site-to-site VPN or Azure ExpressRoute to connect on-premises networks with Azure directly and manage identities using a corporate AD setup.
    • Deploy additional domain controllers in an Azure virtual server and replicate on-premises AD changes...
