[All AWS-SysOps Questions]

An organization with a large IT department has decided to migrate to AWS. With different job functions in the IT department, it is not desirable to give all users access to all AWS resources. Currently the organization handles access via LDAP group membership.
What is the BEST method to allow access using current LDAP credentials?

  • A. Create an AWS Directly Service Simple AD. Replicate the on-premises LDAP directory to Simple AD.
  • B. Create a Lambda function to read LDAP groups and automate the creation of IAM users.
  • C. Use AWS CloudFormation to create IAM roles. Deploy Direct Connect to allow access to the on-premises LDAP server.
  • D. Federate the LDAP directory with IAM using SAML. Create different IAM roles to correspond to different LDAP groups to limit permissions.

Selected Answer: D
The BEST method to allow access using current LDAP credentials in the given scenario is to federate the LDAP directory with IAM using SAML and create different IAM roles corresponding to different LDAP groups to limit permissions (Option D). This approach combines the benefits of LDAP integration, group-based permissions, and centralized IAM management.

Answer A is more suitbale since the option D requires to have custom identity broker application and is used where internal application needs to have access to AWS resource. https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_federated-users.html#id_roles_common-scenarios_federated-users-idbroker

Correct Answer: A Since the organization already handles access via LDAP on-premises, AWS Simple AD would be a good alternative with less effort.
