Password redirects to login page

I am running WP 3.05 with Buddypress 1.2.7, and Andreas09 theme on a multisite blog. http://1two3.co.za/classroom

When I am logged in the password works fine and shows the content, but if I try the password when logged out, I am redirected to the blog's login form.

My understanding is that it is not based on user logins, or am I misunderstanding the documentation?
