Comment 2 for bug 1415242

Hi, I got the same error especially when I activate Swift+Glance. I discovered on my devstack that the Swift proxy configuration
is broken and then Swift cannot verify users token. I fact it was unable to do at least a "swift stat". I think Glance uses Swift as
store so during the devstack stack.sh the image registration fails when the glance server handles the registration request due to Swift 401 the Glance request.

In the proxy-server.conf of swift, auth_host and admin_password are not properly configured ...
I provided a patch to fix that on Gerrit. With that patch it works for me.
