Can not get attribute from resources

[Rico Lin]

We didn't give any attributes_schema in identity resources like user, project, group, etc. I think there might be other resource as well.

Therefore, when we trying to get user name list from a resource group will be impossible.

Those resources don't have attributes, so not attributes schema? I don't understand this bug.

[Rico Lin (rico-lin)]

They have attributes(in client), but since we didn't write the attribute schema and get attribute function for them (in heat). Those resources can't resolve the attribute from heat template.
For example, keystone user has attributes 'name', 'domain_id', etc., but we can't write something like get_attr[user_1, 'name']. It will give you a validation error with no such attribute exists (due to not found in attributes_schema table for OS::Keystone::User resource).
