Hello, please how to get server user from "permissions"? I try this, but does not working: https://ovirt.localhost/ovirt-engine/api/vms/4ekb93a4-64c6-4b13-9927-8f37f2165td2/permissions?follow=permissions.permissions.user._id&search=permission.role._id%20%3D%2000000000-0000-0000-0001-000000000001&limit=1 I need: Show the server user. This means: Find the user ID of a specific server that is in the role with ID: 00000000-0000-0000-0001-000000000001 Thanks for advice.
