我正在一些机器上设置 Openstack。我一直在关注本指南http://docs.openstack.org/liberty/install-guide-ubuntu/直到遇到这个问题：
当我验证图像服务 (Glance) 时，我遇到了以下问题：
$ cat admin-openrc.sh
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=passw0rd
export OS_AUTH_URL=http://Renaissance:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
$ source admin-openrc.sh
$ glance --debug image-create --name "cirros" \
> --file cirros-0.3.4-x86_64-disk.img \
> --disk-format qcow2 --container-format bare \
> --visibility public --progress
curl -g -i -X GET -H 'Accept-Encoding: gzip, deflate' -H 'Accept: */*' -H 'User-Agent: python-glanceclient' -H 'Connection: keep-alive' -H 'X-Auth-Token: {SHA1}7ce8d893ef6cdaca2ed5a876c8211a841455ba65' -H 'Content-Type: application/octet-stream' http://Renaissance:9292/v2/schemas/image
Request returned failure status 401.
Invalid OpenStack Identity credentials.
使用任何其他浏览功能（例如浏览图像列表）我都会得到同样的错误。
自从我遵循指南以来，我认为我的配置是正确的。这是我的 Openstack 服务、项目、用户、角色和端点

我的glance auth 配置（在glance-api.conf 和glance-registry.conf 中）如下所示：
...
[keystone_authtoken]
# Complete public Identity API endpoint. (string value)
auth_uri = http://Renaissance:5000
auth_uri = http://Renaissance:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = glance
password = passw0rd
...
我可以使用 Openstack 获取令牌：
$ openstack token issue

我猜它的api版本问题，但我一直在更改uri中的版本号，但它没有用。任何帮助表示赞赏。谢谢！
