That version is still online in a couple of places. It's at my LJ, here, but all the adult fic on that comm is members-only so you'd need to request membership in order to see it.
Alternatively it's on my website, Wellinghall. Because I have age-warning popups there I can't link directly to the story, but if you go to the author page for Cel and YCD, the original version of "Admittance" is the second fic listed (after the revised one).
