Ah, OK, you are not calling it directly. Yes, that may be one of the
security holes that was patched up in 2.7.4 I think. The solution is
easy: Give index_html a proxy role. In this case "Authenticated" is
enough. f1_index itself if you call it directly will not be
accessible, and that's how it has to be.

That depends very much on what type of objects it is and why you want
that setup.
