Glance NotAuthorized with keystone on Ubuntu 11.10

Hi:
  I am a newbie for openstack. Now I am installing glance with keystone.
keystone use ppa:keystone-core/trunk. The keystone version as follows:
 2012.1~e4~20120206.1578-0ubuntu0ppa1~oneiric1 Proposed OpenStack identity service - Daemons

glance use ppa:glance-core/trunk. The glance version as follows (May this is Essex E4 version ??) :
glance 2012.1~e4~20120209.1254-0ubuntu0ppa1~oneiric1 OpenStack Image Registry and Delivery Service - Daemons
 glance-api 2012.1~e4~20120209.1254-0ubuntu0ppa1~oneiric1 OpenStack Image Registry and Delivery Service - API
 glance-common 2012.1~e4~20120209.1254-0ubuntu0ppa1~oneiric1 OpenStack Image Registry and Delivery Service - Common
glance-registry 2012.1~e4~20120209.1254-0ubuntu0ppa1~oneiric1 OpenStack Image Registry and Delivery Service - registry
python-glance 2012.1~e4~20120209.1254-0ubuntu0ppa1~oneiric1 OpenStack Image Registry and Delivery Service - Python library

  After installed the keystone, use the following command to verify the keystone is ok.
curl -d '{"auth": {"tenantName": "novaproj", "passwordCredentials":{"username": "novaadmin", "password": "novaadmin"}}}' -H "Content-type: application/json" http://127.0.0.1:5001/v2.0/tokens

  After installed the glance, and I modified the glance-api.conf / glance-registry.conf / glance-scrubber.conf. I have the following two problems:
(1) If I add the [paste_deploy] section and set "flavor = keystone" into glance-api.conf and glance-registry.conf, then I will see the following error message in the /var/log/syslog file.
Feb 22 13:34:03 ubuntu43 kernel: [66753.705250] init: glance-api main process ended, respawning
Feb 22 13:34:03 ubuntu43 kernel: [66754.034396] init: glance-api main process (18062) terminated with status 1

Feb 22 13:35:57 ubuntu43 kernel: [66868.426333] init: glance-registry respawning too fast, stopped

(2) If I don't add the [paste_deploy] section, the glance-api and glance-registry service will startup normally. But If I issue the
command "glance details -A 999888777666", I will get the following error message:
Failed to show details. Got error:

    raise exception.NotAuthorized()
NotAuthorized: You are not authorized to complete this action.

   Is there anybody could give me any suggestion to solve these two problems?
  Thanks in advance!
