Integrating AWS with Microsoft Active Directory: A Comprehensive Guide

In this chapter, we’re going to dive into a crucial topic—integration with other identity providers within AWS. Specifically, we’ll explore the integration process with Microsoft Active Directory, focusing on the essential steps and configurations required for a seamless integration experience. This knowledge is invaluable, especially when approaching AWS exams that emphasize identity and access management.

Understanding the Landscape

Imagine an established organization with a thriving identity provider framework. A prevalent choice for this role is Microsoft Active Directory, a trusted solution for managing users and access rights. Now, when this organization decides to migrate to AWS and utilize its cloud resources, the last thing they’d want is a complete overhaul of their existing identity management system. This is where integration comes into play.

The challenge is to enable users to access AWS resources without duplicating user identities or moving them to AWS. The solution lies in making use of the existing identity provider, in this case, Microsoft Active Directory. The integration process involves leveraging SAML (Security Assertion Markup Language) Federation to facilitate seamless authentication between the on-premise Active Directory and AWS services.

Configuration Steps

  1. Setting Up Active Directory Federation Services (ADFS): The first step is to ensure the existence of an Active Directory Federation Services instance in your on-premise environment. ADFS is a SAML-compliant identity provider provided by Microsoft.
  2. Creating a SAML Provider in AWS: Within AWS, you’ll need to create a SAML provider. This establishes a connection between AWS and your ADFS instance.
  3. Configuring Trust: Establish trust between AWS and your on-premise Active Directory Federation Services server. This involves configuring AWS as a trusted relying party in your ADFS setup.
  4. Configuring Claims: Claims define the attributes and information shared during the authentication process. Configure your ADFS to accept incoming requests from AWS and map them to Active Directory groups.

The Workflow in Detail

For users, the integration process is smooth and transparent. Here’s how it works:

  1. Users access the ADFS site.
  2. ADFS authenticates users against Active Directory.
  3. A response is sent from ADFS to the user’s browser.
  4. The user’s browser is redirected to AWS.
  5. Users can now seamlessly utilize AWS resources without explicit authentication, as the process is handled in the background.

Key Takeaway

understanding the mapping of user authorization is paramount. You’ll need to establish a connection between AWS roles and Active Directory groups. AWS roles control access to resources within AWS, while Active Directory groups manage user access on the Active Directory side. Merging these two through proper mapping ensures smooth authorization for users accessing AWS resources.


This chapter has delved into the critical realm of integrating AWS with Microsoft Active Directory, a fundamental process for organizations seeking a unified identity management strategy across their on-premise and cloud environments. By harnessing SAML Federation and configuring the necessary components, seamless authentication becomes a reality, empowering users to access AWS resources effortlessly.

With the integration of these systems, businesses can harness the power of AWS while retaining the robust identity management they’ve already established. Whether you’re preparing for an AWS exam or seeking to implement such integration in a real-world context, the insights provided here serve as a solid foundation for success.
