Comment 1 for bug 1490457

It looks like the behaviour just depends on having all the usual credentials set -- there's no attempt to contact the server.

I'd guess the:

 force_auth=True

below is what's causing _cache_schema to fail, which causes us to revert to v1.

    def _cache_schemas(self, options, home_dir='~/.glanceclient'):
        homedir = os.path.expanduser(home_dir)
        path_prefix = homedir
        if options.os_auth_url:
            hash_host = hashlib.sha1(options.os_auth_url.encode('utf-8'))
            path_prefix = os.path.join(path_prefix, hash_host.hexdigest())
        if not os.path.exists(path_prefix):
            try:
                os.makedirs(path_prefix)
            except OSError as e:
                # This avoids glanceclient to crash if it can't write to
                # ~/.glanceclient, which may happen on some env (for me,
                # it happens in Jenkins, as Glanceclient can't write to
                # /var/lib/jenkins).
                msg = '%s' % e
                print(encodeutils.safe_decode(msg), file=sys.stderr)
        resources = ['image', 'metadefs/namespace', 'metadefs/resource_type']
        schema_file_paths = [os.path.join(path_prefix, x + '_schema.json')
                             for x in ['image', 'namespace', 'resource_type']]

        client = None
        failed_download_schema = 0
        for resource, schema_file_path in zip(resources, schema_file_paths):
            if (not os.path.exists(schema_file_path)) or options.get_schema:
                try:
                    if not client:
                        client = self._get_versioned_client('2', options,
                                                            force_auth=True)
