Disable anonymous users on Open Atrium? first off I'm a beginner to Open Atrium, but am wondering if there is a simple way for all content on the site to require authenticated user permissions.

I'm building an open atrium 2 intranet and do not want anything but the login field accessible to anonymous users

I realize I can simply set the access permissions in every piece of content that is created, but this doesn't seem like a great solution.
If you go to http://yoursite.com/admin/people/permissions and find the "View published content" permission, uncheck it for anonymous users and that should do the trick.
