Is it all possible to redirect all backend administration to the non-domain mapped original URL?
E.G., I have my MU install at http://muinstall.com ….
I create a site for someone, and it initially is at: http://site.muinstall.com.
We then map that site to http://site.com.
My reason: SSL certificates. I can buy one *.muinstall.com SSL cert, versus an individual one for each new site.
Donncha’s plugin claims to do this, but that plugin also breaks the wordpress functions dealing with checking if a user is logged in, so it messes a lot of other stuff I do
