MapPoint WebService authentification with Mono
When migrating a MapPoint WebService application from Windows to Mono/Linux, I encountered “401 Unauthorized” errors. Network analysis revealed slight differences in HTTP headers. Here’s the solution using specific credential handling: var cred = new System.Net.NetworkCredential("---user---", "---password---"); _credCache = new CredentialCache(); _credCache.Add( new Uri( "http://findv3.staging.mappoint.net" ), "Digest", cred ); _finder = new FindServiceSoap(); _finder.Credentials = _credCache; _finder.PreAuthenticate = true;
