Organic Group visible only by authenticated user I want to make the list of OG visible only to authenticated user so they can request membership. I have created a view but it only display group the user is already member of. 

When I change the group visibility from * Private - accessible only to group members* to Public - accessible to all site users this make the group visible to anonymous user too.
I used the Content Access module to deny access to anonymous user. 

In your Organic Group content type admin interface (admin/structure/types/manage/committee) a new ACCESS CONTROL tab appears. Unckeck anonymous user for the view View any committee content.

If authenticated user is check it will over-right Organic Group settings (ie. the Private / Public will have no effect and the content will be accessible to all authenticated user).
