When I open an Issue, I can see links to other pages, such as Comments, Attachments, Resolution, Status Timeline.  A client user seems to see only these four links.  A regular user can see more, such as LInk Issue, Tasks, and Activity Stream.

I want to allow client users to see the Tasks page link in order to view a list of the tasks that are associated with an issue that they can access. Is there some setting that would allow this?
