Comment 7 for bug 1065211

I'm hit up with this error too, and I'm having an exceedingly hard time working around it.
For me the issue stems form ambiguity in the docco's: http://docs.openstack.org/trunk/openstack-compute/install/apt/content/compute-minimum-configuration-settings.html
... as well as cryptic error messages & std-out.

I've been using KeePass to keep track of all my auth credential, so I'm *relatively* sure that I've gotten this right.

I've set some environmental vars to be source with .bashrc ; keystone & glance seem OK (I can run those commands to query the system) & `nova-manage service list` reports everything :-)

for `nova --debug list` I get (redacted): http://pastebin.com/Eq2STQKm
& during a `tail -f /var/log/nova/nova-api.log` while the above is executing, I get: http://pastebin.com/JbvDp4Hv

This would suggest that this is a "simple" authentication issue, and that re-entering a new/correct admin_password value in /etc/nova/nova.conf could resolve the issue. (not sure yet how to go about to do this)

In an issue that could possibly be related (but I'm not sure), I keep getting the following message (error?) on my stdout:
DEBUG nova.utils [req-$HASH$ None None] backend <module 'nova.db.sqlalchemy.api' from '/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/api.pyc'> from (pid=16650) __get_backend /usr/lib/python2.7/dist-packages/nova/utils.py:494

If I disable verbose in the nova.conf, this disappears, but that that does not mean the issue is resolved - merely that it's an issue related to the nova service.

Unfortunately this seems to be an issue that's preventing me from continuing my Folsom installation on Ubuntu 12.04

Will probably report back if I manage to reset the nova auth (not MySQL) & it resolves the issue.
