I found that Ussuri implements the old behaviour by default, and the new behaviour must be configured with [oslo_policy] enforce_scope = true enforce_new_defaults = true in each service configuration file (I have not checked whether services other than Keystone and Nova observe these new oslo_policy settings).

This is on a stable/ussuri Devstack that I spun up about ten days ago.
The documentation for Keystone config option admin_project_name says [1] "If left unset, then there is no admin project". It is not set in my cloud, as evidenced by this:
$ sudo journalctl -u devstack@keystone |grep admin_project_name Jun 01 11:49:55 ussuri devstack@keystone.service[806]: DEBUG uwsgi [-] *resource.admin_project_name = None *{{(pid=2063) log_opt_values /usr/local/lib/python3.6/dist-packages/oslo_config/cfg.py:2589}}
However, when authenticating with any project, I see 'is_admin_project': True in the log, for example here user /linda /with a project-scoped token for project /moon/:

It gets worse. When I configure admin_project_name=admin and admin_project_domain_name=Default, I do see is_admin_project: false in the log, as expected. Still, /linda/, who has the admin role in the /moon /project,//seems to have cloud admin powers. I tested this by creating a Cinder volume type and by listing all instances in the cloud.
So it seems to me that Keystone's old behaviour is in effect: I have admin powers if I have the /admin /role in any project. To me, this looks like a clash between reality and documentation. Am I missing something?
Thanks for comments.
