I would like to ask for an advice. Recently, I was developing a conference site with Drupal 7. The site is hosted at domain1.com. However, the conference is covered by another organization and they require that conference page will be accessible from their own domain something like.: organization.com/conference2014 Fortunately, Drupal has base_url parameter and the site is accessible from organization.com/conference2014 domain. BUt, my problem is when I want to access administration interface of Drupal through organization.com/conference2014?q=user/login I get redirected to organization.com site which is administrated by the organization admin. Moreover, when I access again organization.com/conference2014 - it still asks me for the password.
I got adviced to introduce trigger after the user successfully logs in to the site organization.com/conference2014. It does redirect me but the administration interface/overlays is not there. Any ideas how to tackle this problem?
