OK, the error seems to be in the authorization process.
Hmm... I used chrome and firefox.

Multiple things here:

1. Ensure that the credentials you set up in the creds file and sourced in matches to the one you logged in the horizon
2. All the conf file related to glance must have right keystone authentication urls and creds. Review them once

[ChristianKniep]

Ahh, here we go:
tail -n2 /etc/glance/glance-registry-paste.ini
admin_user = glance
admin_password = service_passaste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
Screw deterministic informatics, there is always a reasons...

Sorry for bothering you, again - great job!
