I need a Issue Tracking System that allow me to share information on a selective manner.

I would be able to define these groups:

• supplier (my company)
• subcontractors
• customer

Then, I would be able to define three type of permissions for issues:

1. Issue that can be viewed only by supplier
2. Issue that can be viewed only by supplier and subcontractors
3. Issue that can be viewed by all (supplier, subcontractors, customer)

I tried redmine but I didn't find a way of hide some issues, they are always visible. There is an open issue and a patch for that but I not sure if it suit well for my situation. With this patch you need always to remember to make it private and there is only a level of permission: private or not. I need something more flexible.

EDIT:

I need a software that works on Fedora Linux.
