Comment 7 for bug 1529058

Hi Rabi

When heat initializes the ceilometer client, it transfers the parameter 'project_name' to ceilometer client and its value is not null.

https://github.com/openstack/heat/blob/master/heat/engine/clients/os/ceilometer.py#L38

but it doesn't transfer the detailed info about domain of the project. I think domain is important to keystone v3. So it leads the exception is thrown by the following code.

https://github.com/openstack/keystone/blob/master/keystone/auth/controllers.py#L199

Do you have any suggestions about it?

Thanks
