# TODO: This should only be set when using project-scoped tokens (and we should
# unsetting things like OS_PROJECT_NAME and OS_PROJECT_DOMAIN_ID when not using
# these) but our tests require both which means we need to export both. This
# causes OSC to (correctly) fail since keystoneauth (which is handling
# authentication for OSC and most other clients) can't tell if we want project-
# or system-scoped tokens. As such, post running this script, the 'openrc' file
# will no longer be usable with OSC or other clients.
#
# The long-term fix for this likely involves a mechanism to switch between
# different sets of auth info on a test-by-test basis. Achieving this almost
# certainly means switching our tests to use clouds.yaml with well-known cloud
# names rather than openrc file currently used.
