To set a cookie and establish a central session for global users who login, redirect users through a central domain after login. Initial design is at: http://www.mediawiki.org/wiki/Auth_systems/SUL2#Redirect_on_Login
This seems related to bug 14736.
Done in Ie3d6523d29ed294c9d9ad44494d2e8f78ff330e9 and follow ups.
