# Sample initial data for Keystone using python-keystoneclient
#
# This script is based on the original DevStack keystone_data.sh script.
#
# It demonstrates how to bootstrap Keystone with an administrative user
# using the OS_SERVICE_TOKEN and OS_SERVICE_ENDPOINT environment variables
# and the administrative API.  It will get the admin_token (OS_SERVICE_TOKEN)
# and admin_port from keystone.conf if available.
#
# Disable creation of endpoints by setting DISABLE_ENDPOINTS environment variable.
# Use this with the Catalog Templated backend.
#
# A EC2-compatible credential is created for the admin user and
# placed in etc/ec2rc.

# By default, passwords used are those in the OpenStack Install and Deploy Manual.
