Comment 4 for bug 1620999

The domain_id will not override the domain_name values and this needs further investigation for why we do see failures.

My current hunch says that the default values for domain_id are not working out so the authentication request is only partially correct (hence a 401).

The workflow is as follows:

1. First swift store driver checks for existence of "glance-swift-store.conf" file https://github.com/openstack/glance_store/blob/5736659fe0edb4c8fd4d583a77017dc8beba774b/glance_store/_drivers/swift/utils.py#L121

2. This being true for your case, _load_config is called https://github.com/openstack/glance_store/blob/5736659fe0edb4c8fd4d583a77017dc8beba774b/glance_store/_drivers/swift/utils.py#L147

3. Defaults are passed, when configs are read from file

https://github.com/openstack/glance_store/blob/5736659fe0edb4c8fd4d583a77017dc8beba774b/glance_store/_drivers/swift/utils.py#L151

and

https://github.com/openstack/glance_store/blob/5736659fe0edb4c8fd4d583a77017dc8beba774b/glance_store/_drivers/swift/utils.py#L100-L107

4. Config values are used here and then passed to ks client https://github.com/openstack/glance_store/blob/5736659fe0edb4c8fd4d583a77017dc8beba774b/glance_store/_drivers/swift/utils.py#L163-L173
