  Some server-side 'SSL' communication fails to check certificates (use

Bug description:
  Grant Murphy from Red Hat reported usage of httplib.HTTPSConnection
  objects. In Python 2.x those do not perform CA checks so client
  connections are vulnerable to MiM attacks.

  """
  The following files use httplib.HTTPSConnection :
  keystone/middleware/s3_token.py
  keystone/middleware/ec2_token.py
  keystone/common/bufferedhttp.py
  vendor/python-keystoneclient-master/keystoneclient/middleware/auth_token.py

  AFAICT HTTPSConnection does not validate server certificates and
  should be avoided. This is fixed in Python 3, however in 2.X no
  validation occurs. I suspect this is also applicable to most OpenStack
  modules that make HTTPS client calls.

  Similar problems were found in ovirt:
