Mauricio - 

We had to specifically tweak the keystone end points with our script. Check to see what you have/need and that it's set up correctly. We are using a fork of the cloudbuilders nova.sh script (Mark provided the link earlier):

If you look at the contents of https://github.com/4P/deployscripts/blob/master/auto.sh, you'll get a sense of the sequence that we use. We checked in keystone sample data that was specific to IP address endpoints in our little test environment, and then copy it those changed configs into place before invoking ./nova.sh run.

In addition I saw some changes on Keystone Admin roles, maybe Dashboard needs to catch up to keystone changes, but again I'm no really sure, Keystone/dashboard developers might give you further information.

>> Have you set up and configured a keystone instance for authentication?  The dashboard only supports Keystone based authentication right now, and it looks like you're trying to connect to nova using Nova's builtin auth.  That howto you are following is quite old.   If you're looking to get openstack up and running on a single box, you might want to try this script (https://github.com/4P/deployscripts/blob/master/nova.sh) which sets up nova+keystone+glance+dashboard on a single host.
