ImportError: Could not import settings 'openstack_dashboard.settings'

There is a common issue with ALLOWED_HOSTS setting. Please be sure to include localhost in the list as well.

If that doesn't solve your issue, please provide more info: version you're using, where did you get the files etc....

More logs would be great, too!

Please see the addition titled " 11/20/2013 11am addition:" in the question.

Thank very much! yum install python-pbr followed by service httpd restart solved this problem.

But when I try to login I get an authentication error. In the browser I get "An error occurred authenticating. Please try again later." and in the logs:

I disabled SELinux and rebooted and I no longer have the autentication issue. While this might not be my fnal solution, I can make progress now.

Thanks Matthias Runge, that solved my question.

pip install pbr solved my problem also.

In a distribution you never should use pip install, because pip installed packages won't see any updates through the distribution.
