    You should be able to use Basic authentication (with SSL for safety of
    course). Basic authentication headers are easy to build on just about any
    platform. Plus, you can send them with the original request
    (pre-authenticate) to avoid the challenge/response.

    However, if NTLM/Kerberos is required for the Web Service, then Charlie is
    absolutely right.
