GCE credentials requested outside a GCE instance

[barucoh]

When trying to access GCS from a GCE instance I have create the following /etc/boto.cfg:

[GoogleCompute]
service_account=default

But when I want to use the same configuration from a non-GCE instance, it will give the error message: GCE credentials requested outside a GCE instance

I was expecting gsutil to try to authenticate as an anonymous caller if it fails with default service account credentials.

Am I missing something here?
