I have a domain trust setup between organization A and organization B. I'm trying to delegate control in organization B so members of a security group in Organization A have the ability to move computers from the computer OU to the workstations OU. I've followed the following to delegate this permission using https://support.microsoft.com/en-us/kb/818091
to a security group in organization A. Whenever anyone who is a member of organization A attempts this it fails. The trust that exist is an external trust. This was working at one time and suddenly stopped and I can't figure why.
