[Bug 1539351] Re: Authorization by user_id does not work in V2.1 API
I think we have now decided the old behavior was never intended, and
will not be supported in Nova moving forward. Permission restriction
should be by project_id.

Title:
Authorization by user_id does not work in V2.1 API
Status in OpenStack Compute (nova):
Won't Fix
Bug description:
In case that authorization for deleting a VM instance is done by user_id,
it works fine in V2.0 API, but it does not work in V2.1 API.
[How to reproduce]
In nova policy.json,
Add the following entries(or modify existing entries like the following).
-----------------------------------------------
"user": "user_id:%(user_id)s",
"compute:delete": "rule:user",
"os_compute_api:servers:delete": "rule:user",
-----------------------------------------------
In nova api-paste.ini,
change 'openstack_compute_api_v21_legacy_v2_compatible' to
'openstack_compute_api_legacy_v2' for "/v2" endpoint.
-----------------------------------------------
[composite:osapi_compute]
use = call:nova.api.openstack.urlmap:urlmap_factory
/: oscomputeversions
/v2: openstack_compute_api_legacy_v2
/v2.1: openstack_compute_api_v21
-----------------------------------------------
In V2.0 API, the authorization by 'user_id' works fine.
Only the user who created a VM instance can delete the VM instance.
In V2.1 API, the authorization by 'user_id' does not work.
Any users in the same project can delete the VM instance that another user created.
