Unauthorized error when using OpenStack API, can't get authentication token from keystone

Question

I want to use the RESTful API, e.g.

https://nova.rc.nectar.org.au:8774/v1.1/1f283209946f428998e8d3930bb038d1

But can not get the authentication token.

I tried the following command to get it (I don't have admin access):

curl -d '{"auth":{"passwordCredentials":{"username": "miranda.zhang", "password": "mypass"}}}' -H "Content-type: application/json"  https://keystone.rc.nectar.org.au:5000/v2.0/tokens

But still get

{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}

I've also had a look at the python-keystoneclient I tried to install it

python setup.py install

But it returns error

Traceback (most recent call last):
  File "setup.py", line 18, in <module>
    import setuptools
ImportError: No module named setuptools

Here is the openrc.sh file generated by my cloud provider, which does not seem to help.

#!/bin/bash

# With the addition of Keystone, to use an openstack cloud you should
# authenticate against keystone, which returns a **Token** and **Service
# Catalog**.  The catalog contains the endpoint for all services the
# user/tenant has access to - including nova, glance, keystone, swift.
#
# *NOTE*: Using the 2.0 *auth api* does not mean that compute api is 2.0.  We
# will use the 1.1 *compute api*
export OS_AUTH_URL=https://keystone.rc.nectar.org.au:5000/v2.0/

# With the addition of Keystone we have standardized on the term **tenant**
# as the entity that owns the resources.
export OS_TENANT_ID=1f283209946f428998e8d3930bb038d1
export OS_TENANT_NAME="pt-1114"

# In addition to the owning entity (tenant), openstack stores the entity
# performing the action as the **user**.
export OS_USERNAME="miranda.zhang"

# With Keystone you pass the keystone password.
echo "Please enter your OpenStack Password: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT

I tried Barak's suggestion to include tenant name, but still get the following:

HTTP/1.1 401 Unauthorized
Vary: X-Auth-Token
Content-Type: application/json
Content-Length: 114
Date: Sun, 29 Dec 2013 08:54:28 GMT

{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}

I have installed the keystone client with Barak's help:

sudo apt-get install python-setuptools
sudo easy_install pip
sudo pip install python-keystoneclient

But using it like this:

keystone --os-tenant-name pt-1114 --os-username USERNAME --os-password PASSWORD --os-auth-url https://keystone.rc.nectar.org.au:5000/v2.0/tokens -os-identity-api-version 2.0 --debug token-get

I got this error, while token-get is clearly a valid option.

I just realized that my existing password for login the web portal won't work as

To access the Nectar Cloud using the OpenStack API you will need to generate a password. By doing so any existing password will be forgotten. To generate a new password click "Reset Password" button.

Problem solved.

Answer 1

You are missing the tenant name in the json block. Here is a working curl request:

curl -i 'http://192.168.9.70:5000/v2.0/tokens' -X POST -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-novaclient" -d '{"auth": {"tenantName": "TENANT", "passwordCredentials": {"username": "USERNAME", "password": "PASSWORD"}}}'

I suggest you install the keystone client using pip:

sudo apt-get install pip
sudo pip install python-keystoneclient

Then run any keystone command with the '--debug' option to see the actual json.
