Are you setting auth.ssl-allow to enable specific users (identified by CN) to access the volume? The following page shows how. 

http://www.gluster.org/community/documentation/index.php/SSL 

Also, note that the CN can't contain spaces. I know that's inconvenient, but space was already used as a delimiter and changing that would have affected backward compatibility.
