Hi.
The python example I have created works for me but is failing for Adriel...and so is the portal...it appears he cannot create a container.
Can someone please check if ac at adrielcafe.com<mailto:ac at adrielcafe.com> and john.m.kennedy at intel.com<mailto:john.m.kennedy at intel.com> have the same permissions? Anyone else have any idea what might be causing such a problem?
Also it would also be interesting to know if the python script works for any of you. It is at https://forge.fi-ware.eu/plugins/mediawiki/wiki/fiware/index.php/Object_Storage_-_User_and_Programmers_Guide.
Thank you.
- John.

John, thanks a lot for example in python! Is beautiful *-*
I tried to run the script from the command line as you suggest:
cdmi_demo.py <username> <password>
it can run the following commands: check_capabilities and create_container.
But when try to list_container or any other command I get:
ERROR:root:Internal Server Error
Internal Server Error
WARNING:root:An error occurred
An error occurred
I try to create a container in FI-LAB, it returns that has been created but does not appear in the list.
Is this some permission problem? Unfortunately the error message is not clear :(

Hello Adriel,
Good to hear you are making progress. I think the issue is that the value required for the cdmi pycurl.URL needs to be modified slightly. It should look like 'AUTH_00000000000000000000000000000150'.
I have significantly updated the user guide at https://forge.fi-ware.eu/plugins/mediawiki/wiki/fiware/index.php/Object_Storage_-_User_and_Programmers_Guide
It now includes comprehensive curl and script examples for authentication and object storage manipulation.
I will try to document similar python examples later on today.
Kind regards,
- John.

John, many thanks for the sample script!
Now we managed to get the initial token, the tenant and the final token using the PycURL<http://pycurl.sourceforge.net/>:
initial_token: GB1TGwIcqU9cols1Fk_BKajInnrO8vXYVO_CpEhKYzRUUQEgTRfE9N2W6YAv1XKdPhAFZGN_96TtA4e08oAqyg
tenant: 00000000000000000000000000000903
final_token: DG-W7yzAxKmEySYH8qe51jY_jes6TDWWrD_-5aKDpjL2gQ1JKZ21T1jjGsNpegoveYnP7SVkkTE7Qkpps43Biw
But when we tried to access the CDMI commands we get the error 401 (Unauthorized).
We created this script based on your. It should create a new container, but the 401 error occurs.
str = StringIO.StringIO()
c = pycurl.Curl()
c.setopt(pycurl.URL, 'http://130.206.82.9:8080/cdmi/{0}/test123'.format(tenant))
c.setopt(pycurl.HTTPHEADER, ['Content-Type: application/cdmi-container', 'Accept: application/cdmi-container', 'X-Auth-Token: {0}'.format(final_token)])
c.setopt(pycurl.PUT, 1)
c.setopt(pycurl.WRITEFUNCTION, str.write)
c.perform()
print str.getvalue()
What are we doing wrong? :(

Hi Adriel,
Yes actually I have now prepared a script that demonstrates the various calls - and uploading and downloading an both simple text content and a binary file. It works on Ubuntu 13.10 with curl installed.
I will post it online shortly, but pls find it attached and paste below in case a firewall blocks it.
Hope this helps,
- John.

# Simple script to show some accesses to CD MI on devstack using curl
#
# Basic flow is :
# Retrieve token
# Check container 'capabilities'
# Create a container, check it
# Put an object in the container, read it, delete it - simple data
# Put an object in the container, read it, delete it - user supplied data file
# Delete the container
#
# There are some pauses in case the user wants to check container using the web
# portal
