    Hello PETERHODES,


    Thank you for your feedback.

    When setting up a one-way trust relationship from the existing on-premises Active Directory (Domain A) to the new Active Directory service in AWS (Domain B), it means that Domain A trusts Domain B. Cloud-based users (in Domain B) can authenticate against the AWS Managed Microsoft AD (Domain B) but they do not have access to on-premises resources (in Domain A).

    A one-way trust is unidirectional: Domain A trusts Domain B, but Domain B does not trust Domain A. This setup ensures that cloud users remain isolated within their own authentication domain and cannot access on-premises systems.

    The one-way trust ensures security by preventing unauthorized access from the cloud to on-premises systems.

    I hope this helps. Let us know if you need any further assistance.

    Regards,
    JR @ Tutorials Dojo
