Co-Author for author.php page

I’m trying to display Co-Author information (using the co-author plugin: http://wordpress.org/extend/plugins/co-authors/) on an author.php page.

For instance if Johnny is a Co-Author, but not a primary author of a post, I want to display his information on an author page: name, website, description.

Currently it is only showing authors that are primary authors on the author.php page.

Any ideas of how to do this?
