Hi OpenStack Community, I am working on a policy configuration to ensure that only owners of a project can delete users within their own project. Below is my current setup and the policy rules I have defined. Current Setup OpenStack deployment using Kolla Ansible 2023.1. Created an owner role with permissions to create, delete, and manage users and projects. But it allows you to delete users from other projects as well. So, I need to achieve the below scenario. Policy Rules yaml "admin_required": "role:admin" "admin_or_owner": "rule:admin_required or (role:owner and project_id:%(target.user.project_id)s)" "identity:delete_user": "rule:admin_or_owner" Scenario User demo with owner role of project X creates users newuser1 and newuser2 assigned to project X. User tester with owner role of project Y creates users myuser1 and myuser2 assigned to project Y. With the above configuration, I aim to ensure that: User demo can only delete newuser1 and newuser2 within project X. User tester can only delete myuser1 and myuser2 within project Y. Thank you for your support.
