====================
Configuring Keystone
====================

Identity sources
================

One of the most impactful decisions you'll have to make when configuring
keystone is deciding how you want keystone to source your identity data.
Keystone supports several different choices that will substantially impact how
you'll configure, deploy, and interact with keystone.

You can also mix-and-match various sources of identity (see `Domain-specific
Configuration`_ for an example). For example, you can store OpenStack service users
and their passwords in SQL, manage customers in LDAP, and authenticate employees
via SAML federation.
