Hey,
I am trying to use libcloud to work with various cloud providers object
storage backend. I have been successfully able to get it working with
Amazon but I've installed two different installations of openstack and it
does not appear to work. My first installation I followed the SAIO guide,
http://docs.openstack.org/developer/swift/development_saio.html this one to
be exact. I am successfully able to connect to it, list, upload, and
download objects from another computer using curl and the swift client.
Whenever I try and connect via libcloud though I get a malformed error
response. This instance uses version 1 of the authentication. I set up
another installation but this time a full installation, following the
openstack documenations, on three servers using keystone for
authentication. Again I am able to successfully connect using curl and
swift client but libcloud I am not. It's quite possible I am doing
something wrong and I've asked in the IRC channel quite a bit over the past
week but that channel seems to be quite dead. I did find that another user
is having this problem and he filed a bug but so far nobody has done
anything to fix it. The bug is located here,
https://issues.apache.org/jira/browse/LIBCLOUD-542 .
So when I run my test script this is the error I'm getting,
[root@bruenor python_scripts]# python pyCloud.py
Traceback (most recent call last):

with the request since it is either malformed or otherwise incorrect. The

Now when I connect to this instance using the swift client I source this
file for authentication,
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://172.16.103.90:35357/v2.0
I have also set LIBCLOUD_DEBUG in my bashrc and here is the output for that
for my request

Also here is the script I'm using to connect, create a container, and list
the containers to check to see if I'm doing something wrong.
