Comment 11 for bug 1454794

During investigation was found next:

Service started with default configuration parameters before config file was updated by puppet.

grep 'auth_' heat.conf
# From keystonemiddleware.auth_token
#auth_uri = <None>
#auth_version = <None>
#delay_auth_decision = false
# options or empty, auth_token will raise an exception on initialization.
#auth_admin_prefix =
#auth_host = 127.0.0.1
#auth_port = 35357
#auth_protocol = https

So we need add additional checks before start services or set small delay before start of service.
