Setup the Keystone Federation Plugin

Create the domain

openstack --os-cloud default domain create rackspace_cloud_domain

Create the identity provider

openstack --os-cloud default identity provider create --remote-id rackspace --domain rackspace_cloud_domain rackspace

Create the mapping for our identity provider

You're also welcome to generate your own mapping to suit your needs; however, if you want to use the example mapping (which is suitable for production) you can.

Example keystone mapping.json file

                ]
            }
        ]
    }
]

The example mapping JSON file can be found within the genestack repository at /opt/genestack/etc/keystone/mapping.json.

Now register the mapping within Keystone

openstack --os-cloud default mapping create --rules /tmp/mapping.json --schema-version 2.0 rackspace_mapping

Create the federation protocol

openstack --os-cloud default federation protocol create rackspace --mapping rackspace_mapping --identity-provider rackspace

Rackspace Configuration Options

The [rackspace] section can also be used in your keystone.conf to allow you to configure how to anchor on roles.

key	value	default
`role_attribute`	A string option used as an anchor to discover roles attributed to a given user	os_flex
`role_attribute_enforcement`	When set `true` will limit a users project to only the discovered GUID for the defined `role_attribute`	false
