Comment 7 for bug 1743603

cmurphy - I see the warning message in keystone log. My environment has service token settings under [keystone_authtoken] section in nova.conf and cinder.conf as well. As explained through execution flow in bug description, warning message is being triggered because of not passing argument value at [0] for "service_token_roles_required" param by loading it from the conf, it should be something like at [1]

[keystone_authtoken]
service_token_roles_required = True
service_token_roles = admin
