Comment 7 for bug 1381961

Mu understanding of Keystone is rudimentary, please comment to clarify it for me.

If public_endpoint or admin_endpoint is not set as Adam mentioned host_url is used and we get the correct url (in case if there is no addition in path, but it's a different story). But in fact this situation hides a real problem.

If these values are set, endpoint_type is used to construct the url and endpoint_type is *always* 'admin' now. In service.py

http://git.openstack.org/cgit/openstack/keystone/tree/keystone/service.py#n114

we create an app with 2 identical routers inside and from my experience the first one is always returned to process a request. I've changed order of append() and started get 'public' Version app always. Obviously, I'm missing something here, but I don't understand that design.

We always deploy 2 (sub)apps (admin and public) on every server, even if admin_bind_host and public_bind_host (deprecated, what should I use instead?) are specified. Those 2 apps identical and the only one is used. So, perhaps we should get rid of the second one?
