Description of problem: We need the ability to prepopulate federated (ie OIDC) users in keystone in order to automate project and user setup in OpenStack from our allocation system (coldfront: https://github.com/ubccr/coldfront). This requires the following patches from keystone to be backported: https://review.opendev.org/c/openstack/keystone/+/448755 https://specs.openstack.org/openstack/keystone-specs/specs/keystone/ussuri/support-federated-attr.html We've tested locally by hand that these work with OpenStack 16.2.1 with limited testing. Our project and user allocation system cannot completely configure a project and users without users first logging in which creates a complicated work flow for onboarding new users to the system.
