mysql error causes openstack deployment to fail

I have been trying to deploy openstack using the scripts provided during the webinar from a few days ago. The install fails at the same place, every time. Below is the section that fails:

TASK: [create the external network] *******************************************
fatal: [cloud-controller] => failed to parse: /root/.ansible/tmp/ansible-1373991065.17-51641315664934/quantum_network:120: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
module.fail_json(msg = “Error authenticating to the keystone: %s” %e.message)
{“msg”: “Error authenticating to the keystone: Authorization Failed: Unable to communicate with identity service: {"error": {"message": "An unexpected error prevented the server from fulfilling your request. (OperationalError) (1045, \"Access denied for user ‘keystone’@‘localhost’ (using password: NO)\") None None", "code": 500, "title": "Internal Server Error"}}. (HTTP 500)”, “failed”: true}

FATAL: all hosts have already failed – aborting

PLAY RECAP ********************************************************************
to retry, use: --limit @/var/tmp/ansible/site.retry

cloud-compute : ok=15 changed=3 unreachable=0 failed=0
cloud-controller : ok=48 changed=8 unreachable=1 failed=0

I have tried logging into the database as keystone:keystone and that fails as well. Any help would be greatly appreciated here.
