your session cookie associated domain logged in at, if login @ domain1.com not logged in @ organization.com. i'm assuming organization.com has rewriterule configured conference2014 points domain? if so, can configure redirect pass query string redirect, this:

rewriterule ^conference2014/?(.*) http://domain1.com/$1 [l,ne,qsa] 

(qsa piece we're interested in, "query string append")

this allow access http://organization.com/conference2014?q=user etc.
