Sorry for the delay right now I'm on other projects and I can't keep track of this. I'm going to leave it in product review and when we close some issues I'll look for the author to discuss what to do with this request

@Ian2012, do you think this is still necessary? Or if you are not affected by this, who should be interested?

[Ian2012]

This is still necessary, for customers who wants to configure authentication for all their sites

This also affects the default Aspects installations
