Comment 1 for bug 1277425

I see the same problem when using Nova v3 API:

$ nova --os-compute-api-version 3 boot --image cirros-0.3.1-x86_64-uec --flavor m1.nano vm01
ERROR: Invalid user / password (HTTP 401)
$

This problem does not happen when using Nova v2 API:
$ nova --os-compute-api-version 1.1 boot --image cirros-0.3.1-x86_64-uec --flavor m1.nano vm01
