Step 5: Verify and Test the Integration

The hosted UI automatically displays both authentication options.

• Native Cognito User Pool authentication (existing functionality)
• Microsoft Entra ID federation (newly implemented)

Now, Amazon Cognito seamlessly handles the authentication flow regardless of which identity provider is used, as shown below.

2. Go to Sign-in experience and locate the Federated identity provider sign-in section
3. Select Add identity provider and choose SAML as the provider type

4. Configure the identity provider with these settings:

Step 2: Configure SAML Parameters

You’ll need to retrieve key information from your Cognito User Pool to properly configure the SAML parameters:

1. In the AWS Console, locate your Cognito User Pool and note the User Pool ID

2. Record the Cognito Domain from your User Pool settings

3. In Azure Portal, configure the following SAML parameters:
   • Identifier (Entity ID): Format as urn:amazon:cognito:sp:{User pool ID}
   • Reply URL (Assertion Consumer Service URL): Format as {Cognito domain}/saml2/idpresponse
4. Save your configuration changes

Overview

This comprehensive guide walks you through the process of integrating Microsoft Entra ID (formerly Azure AD) with Amazon Cognito to enable seamless federation authentication for your web application.

What we do

Our web application currently uses Amazon Cognito User Pool for authentication, limiting access to Cognito-registered users only. This guide demonstrates how to extend authentication capabilities by implementing Microsoft Entra ID federation, allowing your enterprise users to access the application using their existing Microsoft credentials.

Step 1: Configure SAML in Microsoft Entra ID

Begin by setting up a SAML application in Microsoft Entra ID to establish the identity provider side of the federation:

1. In Azure Portal, access Microsoft Entra ID, then select Enterprise applications
2. Select New application to create a custom application integration

3. Click Create your own application to configure a custom SAML provider

4. Configure the application with the following parameters:

   • Application name: (your preferred application name)
   • Select Integrate any other application you don’t find in the gallery (Non-gallery)

5. Click Create to generate the application
