Can't access site dashboard through main blog, pro sites issue?

I have a multi site network, I'm running pro sites and domain mapping amongst other WPMU DEV plugins. I love the new work done to Pro sites, however, I've noticed when my users login to their account through the main blog, then click on "admin dashboard" to visit their dashboard, they get the following error:

"You attempted to access the "SITE NAME" dashboard, but you do not currently have privileges on this site. If you believe you should be able to access the "SITE NAME" dashboard, please contact your network administrator.

If you reached this screen by accident and meant to visit one of your own sites, here are some shortcuts to help you find your way."

Is there a way to enable it so that my users can access their dashboard, but by logging into their account on the main blog?

here's a link to a screencast I made showing the issue:
