To use the http authentication one has to override the GetWebRequest function and append http authorization header as follows: using System; using System.Collections.Generic; using System.Text; using System.Web.Services.Protocols; using System.Net; namespace WindowsApplication1.WebServiceAPI { public class WebServiceAPIAuth : WebServiceAPI { public string UserName; public string Password; private string S2Base(string s) { byte [] ba; ba=Encoding.ASCII.GetBytes(s); return Convert.ToBase64String(ba); } protected override System.Net.WebRequest GetWebRequest(Uri uri) { CredentialCache cc = new CredentialCache(); WebRequest wr = base.GetWebRequest(uri); wr.Headers.Add(HttpRequestHeader.Authorization, "Basic "+S2Base(UserName+':'+Password)); return wr; } } }

For classes, the default ctor is run, if no explicit value is provided in this vector ctor: vector(size_type count, const T& value); . -- The Blog: Bits and Pieces
