Hi,

I followed oficial documentation to install openstack on two vagrant boxes 1 controller and 1 compute. All went well and openstack services works now.

with my admin rc file i can create image, get token etc.

So i think my credentials are true. But i can not login via dashboard. I set all my horizon settings same with as documented here: http://docs.openstack.org/mitaka/install-guide-ubuntu/horizon-install.html

I set django logging to a file and i got belows when i try to login:

Beginning user authentication
Attempting to authenticate for admin
The resource could not be found. (HTTP 404)
Login failed for user "admin".
Load condition failed for panel: identity_providers
Load condition failed for panel: mappings

How can I debug the case more detailed? How can I go futher? What can be the resource which is missing mentioned in error message?

Thanks..
