Title:
  Authenticating with user 'admin' from the UI fails  - Error in
  keystone.log

Status in OpenStack Dashboard (Horizon):
  Expired
Status in OpenStack Identity (keystone):
  Expired

Bug description:
  I am setting up OpenStack Mitaka on Ubuntu 14.04 server by following :
  http://docs.openstack.org/mitaka/install-guide-ubuntu/

  Once I install the dashboard, when I try to login using the 'admin'
  account, it gives me the following error on the UI 'An error occurred
  authenticating. Please try again later.'

  On further investigation, I see the following error in
  /var/log/apache2/keystone.log

  If you notice the last line, it is referring to 'build_auth_contet' in
  keystone-paste.ini which might be a typo for build_auth_context

  Thanks,
  Kiran Vemuri

  -- Update:

  I was able to work around the previous error by copying
  'build_auth_context' filter to 'build_auth_contet' as follows

  [filter:build_auth_contet]
  use = egg:keystone#build_auth_context

  [filter:build_auth_context]
  use = egg:keystone#build_auth_context

  and restart apache2

  But now I see the following error in /var/log/apache2/error.log
