What permission controls the Iterations checkbox in TFS 2013?

Question

I would like to grant a user the ability to check and uncheck iteration checkboxes for a specific iteration path in a TFS 2013 Team Project. This person is a scrum master and would like to be able to manage the iterations that appear in the Team backlog.

I have granted the following iteration level permissions but the checkboxes are still read-only for the user.

The only way I have found to grant edit rights to these checkboxes is by adding the user to the Project Administrators group which I would rather not do. Is there another way to do this?

Answer 1

As you can see on the authorization matrix on MSDN, the Schedule Sprints activity is possible through the Team Administrator.
