OpenStack Keystone
==================

Keystone provides authentication, authorization and service discovery
mechanisms via HTTP primarily for use by projects in the OpenStack family. It
is most commonly deployed as an HTTP interface to existing identity systems,
such as LDAP.

From Kilo release Keystone v3 endpoint has definition without version in url

Sample pillars

.. caution::

    When you use localhost as your database host (keystone:server:
    atabase:host), sqlalchemy will try to connect to /var/run/mysql/
    mysqld.sock, may cause issues if you located your mysql socket elsewhere

Documentation and Bugs
======================

To learn how to deploy OpenStack Salt, consult the documentation available
online at:

    https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate bug tracker. If you obtained the software from a 3rd party
operating system vendor, it is often wise to use their own bug tracker for
reporting problems. In all other cases use the master OpenStack bug tracker,
available at:

    http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base
their work on the latest formulas code, available from the master GIT
repository at:

    https://git.openstack.org/cgit/openstack/salt-formula-keystone

Developers should also join the discussion on the IRC list, at:
