I recently installed Organic Groups along with Casetracker and I am running into a couple of obstacles.

Setup:
Casetracker is installed and I have setup 10 projects to use with Casetracker.
I have Organic Groups installed and have created 10 groups that will work the projects.
On the project node itself I select the audience(organic group) I want the trouble ticket to go to or be associated with.

The problem I am running into is this:
I have 5 roles setup on site and 3 out of the 5 have permissions to select an organic group audience when creating a Trouble Ticket. The role of "authenticated user" is a low level role on the site and does not have permissions to select a group as I do not have one setup for "authenticated users". I want the "authenticated" users to be able to select an audience (target the audience responsible for the trouble ticket) without me having to set they're permissions to high. The only permission I've been able to enable where the "authenticated users" can select an audience is "administer nodes" which is obviously not an option.

Is there an easy way of doing this without having to add another Group for "authenticated users" or an option in the permissions area that I am missing? Or a configuration option in Organic Groups that I looked over?
