Open Stack

Hey, all.  I am trying to figure out how to see which users are 
associated with which projects, and, for the life of me, I can't seem to 
figure out the magic juju from the CLI.  Any suggestions?  I thought 
things like "openstack user show" or "openstack project show" would do 
the job, but only for the default user, not for additional ones.

Thanks!
