[IronPython] Newbie: IronPython and WSE 3.0 (translation from C# example)?

Looks like Webservice.Load is not returning a WebServicesClientProtocol. In the C# world you are instantiating a UserServiceWse. You could do the same in python so:
userService = UserServiceWse()

I assume the definition of that class would look like this:
def UserServiceWse(WebServicesClientProtocol):
        def __init__(self): #The constructor.
                self.blah = foo

Hi --

I'm trying to hook up IronPython to web services secured by Web Services
Enhancements (WSE) 3.0. I have some C# sample code that I'm trying to
convert to Python and am running into some trouble. I'm a C# and Windows
..NET newbie (using IronPython from the commmandline), so the libraries
in question are foreign to me, so I was hoping someone could help me
resolve this. The sample code shows:

using Microsoft.Web.Services3;
using Microsoft.Web.Services3.Design;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3.Security.Tokens;
namespace TpIntegration
public class TpPolicy : Policy {
  public TpPolicy() {
    Assertions.Add(new UsernameOverTransportAssertion());
  public static UsernameToken GetUsernameToken(string username, string
password, PasswordOption passwordOption) {
    UsernameToken token = new UsernameToken(username, password,
    ISecurityTokenManager securityTokenManager =

    return token;
  public static void ApplyAutheticationTicket(WebServicesClientProtocol
protocol, string userName, string password) {
    UsernameToken token = GetUsernameToken(userName, password,
    protocol.SetPolicy(new TpPolicy());

This is then called using something like this:

UserServiceWse userService = new UserServiceWse();
TpPolicy.ApplyAutheticationTicket(userService, "admin", "admin");

I've taken a swing at converting it:

import Microsoft.Web.Services3
import Microsoft.Web.Services3.Design
import Microsoft.Web.Services3.Security
import Microsoft.Web.Services3.Security.Tokens

def getUsernameToken(username, password, passwordOption):
    token =
password, passwordOption)
    securityTokenManager =
    return token

def applyAutheticationTicket(protocol, userName, password):
    token = getUsernameToken(userName, password,

but when calling it:

userService =
username = "test"
password = "test"
applyAutheticationTicket(userService, username, password)

I get the following error:

AttributeError: 'UserService' object has no attribute 'SetClientCredential'

Any suggestions on how to debug this further? In case it matters, this
is code from
