Open Stack

Hi, all
I've installed nova/glance in Diablo official release, and all worked.
Then I've tried to install keystone ( 
https://github.com/openstack/keystone/commit/0425fba560e7d68e52f922667972765e64ad17dc 
posted in last meeting )

and used sample config files in example/paste/...

running nova-api I obtain :

(nova): TRACE: ImportError: <module 'nova.api.ec2' 
from '/usr/lib/python2.6/site-packages/nova/api/ec2/__init__.pyc'> has 
no 'ToToken' attribute

so I digged in nova/api/ec2/__init__.py and I noticed that following class was 
removed:
class ToToken(wsgi.Middleware):
    """Authenticate an EC2 request with keystone and convert to token."""

Is there a reason for this or something now is called in a different way?

Is there a adviced keystone release able to work with nova diablo?

thank you!
Carlo


ps. a few days ago a similar thread was opened in mailing list but in that 
case the issue was only a strong difference in release between nova and 
keystone
