Can't work in a private only network

[talbarda]

I have a virtual server on softlayer with closed public network, and when I try to run the following, it fails (Exception below):
import object_storage
sl_storage = object_storage.get_client(X,Y, datacenter='dal05',auth_url='http://dal05.objectstorage.softlayer.net/auth/v1.0') # WORKS
sl_storage['barda'].exists() # FAILED

In order to debug the problem, we changed the "/usr/lib/python2.7/site-packages/object_storage/transport/httplib2conn.py" file to print the request url and we found that it sends a request to the public url "http://dal05.objectstorage.softlayer.net/auth/v1.0" instead of the private url in the input auth_url "http://dal05.objectstorage.service.networklayer.com/auth/v1.0"

Exception:
