TF400411: The following user is not a valid Project Server resource: {0}. Also, the following account names are registered in TFS for the user but they do not uniquely identify a Project Server resource: {1}. Ensure that only one of the account names under which the user is registered in TFS is registered in Project Server. Or, you can add the Team Foundation user to the enterprise resource pool of the PWA and to the Team Members group. Then, add the user to the resource pool of the mapped enterprise project plan and publish the plan.
