COMPONENT NAME

UI, Permissions, Access Controll

CLOUDSTACK VERSION

4.17 onwards

SUMMARY

The https://github.com/apache/cloudstack/pull/4339 pull request allows CloudStack's domain admins to change their domains configurations. This option gives domain admins power to abuse CloudStack system IPs, create public templates, share their templates with other domains, and many more unwanted effects to the environments even though the root admin disallow these actions in the first place.

Domain level settings
account.allow.expose.host.hostname
allow.public.user.templates
preferred.storage.pool
share.public.templates.with.other.domains
use.system.public.ips

As of now there isn't a global setting to revert this changes. I have the following suggestions let me know what do you think.

1. Add a global setting to override this behaviour.
2. Move these setting to global level so domain admins can't change them.
3. Give priority to the global level settings, so if domain admins override a setting.

STEPS TO REPRODUCE

1. Login as a root admin
2. Configure the domain
3. Log out
4. Login as a domain admin
5. Configure the domain

EXPECTED RESULTS

Root admin configurations are **NOT** overridden.

ACTUAL RESULTS

Root admin configurations are overridden.
