Greetings,
I don't think you're going to get such filtering and querying with just custom policy. Essentially, this should ideally be done with lower level logic close to the database to enforce the view, as doing it in the API before returning the result set to the user is ultimately inefficient. Ironic has a similar concept where baremetal nodes lists are filtered, and the enforcement of that (as in the need) is identified in the API layer through policy, and the overall query to the database only returns the relevant list matching the user's project.
It was actually really simple for us to implement in ironic, but is definitely some code deep down in the stack.

Hello openstack community, I am currently working on an OpenStack kolla ansible 2023.1. I have created a custom role " owner "
*Objective:*
- Users with the owner role can only list users within their project.
- Avoid additional API calls for filtering users by project.
*Current Challenge:* Using direct API calls, the list users API currently returns all users without any project-specific filtering. While additional API calls to the role_assignments endpoint can achieve the desired filtering, this approach is not efficient and doesn't restrict access at the API level.
I am considering defining custom Keystone policies to achieve thisrestriction. However, I am unsure how to properly configure these policies to enforce project-specific access control effectively.
Thanks in advance
