I don't know if the rule.yaml is being rendered correctly as seen below:

ubuntu@coreycb-bastion:~/charms/focal/openstack-dashboard$ juju run --application openstack-dashboard cat /etc/openstack-dashboard/policy.d/keystone_policy.d/rule.yaml
- Stdout: |
    {'identity:get_domain': '!', 'identity:list_domains': '!', 'identity:list_domains_for_usern': '!',
      'identity:update_domain': '!'}
  UnitId: openstack-dashboard/0
- Stdout: |
    {'identity:get_domain': '!', 'identity:list_domains': '!', 'identity:list_domains_for_user': '!',
      'identity:update_domain': '!'}
  UnitId: openstack-dashboard/1
- Stdout: |
    {'identity:get_domain': '!', 'identity:list_domains': '!', 'identity:list_domains_for_user': '!',
      'identity:update_domain': '!'}
  UnitId: openstack-dashboard/2

ubuntu@juju-be7b83-zaza-b74897d248b9-3:~$ sudo cat /etc/openstack-dashboard/policy.d/keystone_policy.d/rule.yaml
{'identity:get_domain': '!', 'identity:list_domains': '!', 'identity:list_domains_for_user': '!',
  'identity:update_domain': '!'}

Should this instead be formatted like this?

ubuntu@juju-be7b83-zaza-b74897d248b9-3:~$ sudo cat /etc/openstack-dashboard/policy.d/keystone_policy.d/rule.yaml
'identity:get_domain': '!'
'identity:list_domains': '!'
'identity:list_domains_for_user': '!'
'identity:update_domain': '!'
