AWS Managed Microsoft AD increases directory sharing limits

AWS has increased the account sharing limits for AWS Managed Microsoft AD directory sharing, allowing customers to share their directories with significantly more AWS accounts. The Standard Edition limit has increased from 5 to 25 accounts, while the Enterprise Edition limit has expanded from 125 to 500 accounts. These enhanced limits remove previous technical constraints and enable organizations to scale their directory infrastructure more effectively across their AWS environments.

The increased limits help enterprise customers consolidate their Active Directory infrastructure and reduce operational complexity by supporting larger AWS account footprints from a single managed directory. Organizations can now centralize authentication and management across hundreds of AWS accounts, which in turn helps eliminate the need for complex workarounds with multiple directory deployments.

This feature enhancement is available in all AWS Regions where AWS Managed Microsoft AD is currently supported.
