Privacy Plugin - After Login Take to Site - Not Dashboard

I have the sitewide privacy plugin installed on my wordpress mu site (upgraded to 3.1 now). The question I have is about the three options this plugin adds. After users log in it takes them to the dashboard. Is there any way that after someone logs in it will redirect them to the main site itself? Is this managed by the plugin, or by regular login functions?

If it is important I also have the shibboleth plugin managing login.

Thanks for your thoughts!
