Python SOAP client with Zeep - authentication

I am trying to use Zeep to implement a SOAP client, as it seems the only maintained library at the moment:

So, trying to use Zeep, I am stuck with the authentication required by the server to access the WSDL.

Such operation was quite easy with ZSI:

from ZSI.client import Binding
from ZSI.auth import AUTH

b = Binding(url='http://mysite.dom/services/MyWebServices?WSDL')
b.SetAuth(AUTH.httpbasic, 'userid', 'password')

and I can find something similar in __main__.py of Zeep:

from six.moves.urllib.parse import urlparse
from zeep.cache import InMemoryCache, SqliteCache
from zeep.client import Client
from zeep.transports import Transport

cache = SqliteCache() if args.cache else InMemoryCache()
transport_kwargs = {'cache': cache}
result = urlparse(args.wsdl_file)
if result.username or result.password:
    transport_kwargs['http_auth'] = (result.username, result.password)
transport = Transport(**transport_kwargs)
client = Client(args.wsdl_file, transport=transport)

but that does not work in my case, I get an error:

Exception: HTTPConnectionPool(host='schemas.xmlsoap.org', port=80): Max retries exceeded with url: /soap/encoding/ (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f3dab9d30b8>: Failed to establish a new connection: [Errno 110] Connection timed out',))

In my case the API I was working with required WS-Security (WSSE) rather than HTTP.

from zeep import Client
from zeep.wsse.username import UsernameToken

client = Client(<wsdl_url>, wsse=UsernameToken(<username>, <password>)

Probably with the newer Version of zeep the older solution does not work anymore. Here is the new way:

from requests.auth import HTTPBasicAuth  # or HTTPDigestAuth, or OAuth1, etc.
from requests import Session
from zeep import Client
from zeep.transports import Transport

session = Session()
session.auth = HTTPBasicAuth(user, password)
client = Client('http://my-endpoint.com/production.svc?wsdl',
            transport=Transport(session=session))

For Basic Access Authentication you can use the HTTPBasicAuth class from the requests module, as explained on Zeep documentation http://docs.python-zeep.org/en/master/transport.html:

from requests.auth import HTTPBasicAuth  # or HTTPDigestAuth, or OAuth1, etc.
from zeep import Client
from zeep.transports import Transport

client = Client('http://my-endpoint.com/production.svc?wsdl',
    transport=Transport(http_auth=HTTPBasicAuth(user, password)))
