[drupal-support] Page not found vs. Access denied

[Gabriele Caniglia]

On my website, anonymous users cannot access posts in defined categories.
I use the taxonomy access module.

This way, guests don't see the posts at all, but logged users can see 
and read them.

The problem is that, accessing the post's URL when not logged in, I 
don't see anything like:
"Access denied. You have to be registered to see this post. Please login 
or register to this website"

Instead, users get a misleading "404 - Page non found" error.

Is there a way to correct this?

Thanks for your help.
