Granting AWS Managed Microsoft AD users and groups access to AWS resources with IAM roles
AWS Directory Service provides the ability to give your AWS Managed Microsoft AD users and groups access to AWS services and resources, such as access to the Amazon EC2 console. Similar to granting IAM users access to manage directories as described in Identity-based policies (IAM policies), in order for users in your directory to have access to other AWS resources, such as Amazon EC2 you must assign IAM roles and policies to those users and groups. For more information, see IAM roles in the IAM User Guide.
