Implementing Identity Management on AWS

By: Jon Lehtinen

Overview of this book

AWS identity management offers a powerful yet complex array of native capabilities and connections to existing enterprise identity systems for administrative and application identity use cases. This book breaks down the complexities involved by adopting a use-case-driven approach that helps identity and cloud engineers understand how to use the right mix of native AWS capabilities and external IAM components to achieve the business and security outcomes they want. You will begin by learning about the IAM toolsets and paradigms within AWS. This will allow you to determine how to best leverage them for administrative control, extending workforce identities to the cloud, and using IAM toolsets and paradigms on an app deployed on AWS. Next, the book demonstrates how to extend your on-premise administrative IAM capabilities to the AWS backplane, as well as how to make your workforce identities available for AWS-deployed applications. In the concluding chapters, you’ll learn how to use the native identity services with applications deployed on AWS. By the end of this IAM Amazon Web Services book, you will be able to build enterprise-class solutions for administrative and application identity using AWS IAM tools and external identity systems.

Creating the trust between AWS Managed AD and on-premises AD

As we have touched so many different AWS services and created so many resources throughout this chapter, we should take a moment to reflect upon why we went through all of this effort. The aim of this exercise was to provide a mechanism by which non-administrative user identity information could be made available to applications and resources hosted inside our AWS environment. We elected to make our on-premises Active Directory accounts available through AWS Managed AD care of a two-way trust. Once the trust has been established, the accounts in both domains will be able to access resources in each of the domains. Applications that use Active Directory for user authentication or attribute lookup will be able to look inside both domains for user information.

Now that we have done all of the necessary supporting work to get to this point, let's configure the forest trust between the AWS Managed AD and our on-premises...
