Hello
Thank you for posting in Q&A forum.
The error "Error 1332: No mapping between account names and security IDs was done." means that the user with SID s-1-5-21-647484227-1344466760-2872218628-1715 is not existing in domain.
The error below means the object is already in the Remote Desktop Users, you do not need to add them to Remote Desktop Users group.
Configure Domain_3. object already member of Remote Desktop Users. Configure Domain_2. object already member of Remote Desktop Users. Configure Domain_1. object already member of Remote Desktop Users.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
