The authorization tab is available on all objects in the ITP/MDK Repository, except Models and revisions of objects. On this tab, roles can be assigned to users. It consists of two panes: the top pane or Roles pane and the lower or Users pane. The Roles pane lists all available roles in the ITP/MDK Repository. When a Role is selected the Users pane lists all users that have the selected Role for the project. This lower pane also allows you to add and remove users to the Role for this project.
