The admin role is, in principle, able to perform cloud-global tasks like managing projects, users, external networks etc. Domain admins are limited to work on users, groups and projects in a domain, nothing else. There is no such thing as a project admin. What is your "project admin" supposed to do?

Generally, you change user privileges by modifying policies. Depending on the particular requirements of your "project admin" role, that may be possible.

I think this may be related to this bug:

I tried fixing according to the patch but couldn't get it to work for Mitaka. I ended up addressing this by editing the keystone policy.json file like this (replace with your specific IDs):

"admin_domain_admin_user": "user_id:cb225fdec10b492f934c242d481e0a1d",
"OS_admin": "role:Admin and domain_id:d2649e20f18d47f6a287d15a88b23541",
"cloud_admin": "rule:admin_domain_admin_user or rule:OS_admin",

I have a domain just for my openstack adminstrators with the id in the OS_admin rule. The first rule is the admin user in the admin_domain. The cloud_admin rule now just establishes the "built-in" admin account or my administrators in a unique domain as a cloud_admin.

Hope this helps, David Reno
