Comment (by jeremyfelt):

 [https://core.trac.wordpress.org/attachment/ticket/17376/17376.3.diff
 17376.3.diff] takes a different approach from other patches on this ticket
 and watches for admin requests during `get_site_by_path()`. If
 `is_admin()` returns true, it alters the search from multiple possible
 path segments to one possible path segment.

 For `foo.bar/site2` on a network where only `foo.bar/` and
 `foo.bar/site1/` exist:
 * `foo.bar/site2/` will search both `site2/` and `/` as paths
 * `foo.bar/site2/wp-admin/` will search only `site2/` as a path.

 When a site is not found, the patch redirects to the network's primary
 site `wp-admin/` path. At that point, if the user does not have access, we
 already throw a fairly helpful message showing the current sites that the
 user does have access to.

 If the user does have access, the redirect is silent. I'm not sure that we
 should worry about additional admin notices for this scenario.

 Anything outside the range of possible path segments—`foo.bar/site2/page1
 /wp-admin/` will result in a 404 for the primary site, the current
 behavior.
