Question

Difficulty: EasyIdentity Federation and Directory Services

A company wants to grant its on-premises Active Directory users access to the AWS Management Console. The solutions architect needs to configure identity federation using AWS IAM Identity Center to allow users to sign in with their existing corporate credentials.

Which two actions must the solutions architect perform to establish this integration? (Select TWO.)

  1. Connect the on-premises Active Directory to AWS using AD Connector.Answer
  2. Enable AWS IAM Identity Center and configure the identity source to use the connected directory.Answer
  3. C
    Create individual IAM users with long-term credentials for each Active Directory user in AWS IAM.
  4. D
    Distribute the AWS account root user credentials to the corporate Active Directory administrators.

Answer

Connect the on-premises Active Directory to AWS using AD Connector, and enable AWS IAM Identity Center to use the connected directory as the identity source.
To integrate an on-premises Active Directory with AWS for federated access, the solutions architect must connect the on-premises directory to AWS (e.g., using AD Connector) and configure AWS IAM Identity Center to use that directory as the identity source. This allows users to authenticate using their existing corporate credentials without storing credentials in the AWS cloud.

Step-by-Step Solution

1
Establish a connection between the on-premises Active Directory and AWS.
AWS Directory Service AD Connector is configured to route authentication requests to the on-premises domain controllers.
This avoids synchronization or replication of passwords to AWS and allows directory queries to reach the on-premises infrastructure.
2
Configure AWS IAM Identity Center to use the external directory.
IAM Identity Center is configured with the connected directory as its identity source.
This allows corporate users to log in to the AWS Management Console with their existing Active Directory credentials.

Key Concept

Federating an on-premises Active Directory with AWS IAM Identity Center using AD Connector to allow single sign-on without creating individual IAM users.
