Hi,

I'm using Icehouse and enabled Keystone v3 multi-domain feature in
Horizon and Nova. I created a non-default Keystone domain and added
projects and users in it. However, if a user (in the non-default
domain) tries to list/create VM image or launch VM instance in
Horizon, it gets unauthorized error from Glance.

I checked Glance source codes (glance/common/auth.py), and it seems
Glance only supports Keystone v1 and v2 APIs. So if the user is using
Keystone v3 auth token, Glance can't validate the auth token with
Keystone.

Am I correct?  If so, does anybody has a patch to enable Keystone v3
API support in Glance?
