Comment (by Denis-de-Bernardy):

 Replying to [comment:12 jeremyfelt]:

 I'd argue it should be this instead:

 1. The request comes in for `http://validnetwork.com/invalid-site/wp-
 admin/`
 2. WordPress establishes that the network - `$current_site` - is valid.
 3. WordPress establishes that the requested path does not match a current
 site and fills `$current_blog` in with the network's primary site data.
 4. Check that the user can access the main site's admin area. If not, fail
 with an error message that says permission denied.
 5. If yes, redirect to the primary site's admin UR -
 `http://validnetwork.com/wp-admin/`
 6. Show some sort of message indicating that the request was invalid and
 we redirected.

 The above is what my first patch does.
