How to attach X509Certificate2 to webservice (Apple GSX / C# specific) - web-services

Apple released their New Generation WSDL on the 15 of August this year (2015) and the big change was that every call to the WSDL had to be validated with a certificate file.
I've done the process to get the certificate from Apple, and I've whitelisted our server IP, and I've even verified that I can get access to the service endpoint from our server by coding a simple interface using HttpWebRequest where I easily can attach the certificate using webRequest.ClientCertificates.Add(), so I know everything is ready for it to work.
But, my problem arises when I download the WSDL from https://gsxwsut.apple.com/apidocs/prod/html/WSArtifacts.html?user=asp
I import the WSDL into Visual Studio and when I try to make an instance of the client class, the only one I find is GsxWSEmeaAspPortClient, which seems to be correct as it has all the functions for authenticate and various tools, but it does not have ClientCertificates. It does have ClientCredentials which have ClientCertificate, but when I try to set the cert there, it's as tho it's never set.
I'm guessing the service code transmits the data via either HttpWebRequest or WebRequest, so if I just can get to the request code from my instance of the class (GsxWSEmeaAspPortClient) I can probably fix it, but I can't seem to get there.
I've looked at this question: How can I connect with Apple's GSX NewGeneration webservices with WCF? which suggests it really should be that easy, but I don't have the GsxWSEmeaAspService, only the GsxWSEmeaAspPortClient from my Visual Studio's generation of the WSDL.
If anyone has any ideas which can point me in any direction towards victory I'd be eternally grateful.
I'm using Visual Studio 2013 and the solution is .Net v4.5.1 if that makes any difference.

I've pasted new code here:
public void Authenticate() {
// Use custom binding with certificate authentication
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
// Create service endpoint
// Use proper endpoint address - eg. gsxapi.apple.com for production
EndpointAddress endpoint = new EndpointAddress("https://gsxapiit.apple.com/gsx-ws/services/emea/asp");
// Create new service
Apple.GsxWSEmeaAspPortClient service = new Apple.GsxWSEmeaAspPortClient(binding, endpoint);
// Set loaded certificate
service.ClientCredentials.ClientCertificate.Certificate = new X509Certificate2(
"[PathToContainerFromStep7].p12",
"[YourPasswordFromStep8]");
// Create authenticate request object
Apple.authenticateRequestType auth = new Apple.authenticateRequestType()
{
languageCode = "en",
userId = "[YourAppleServiceAccountNumber]",
userTimeZone = "[YourTimeZone]",
serviceAccountNo = "[YourSoldToNumber]"
};
// Authenticate to Apple GSX
Apple.authenticateResponseType session = service.Authenticate(auth);
// Assign your new session id object
userSessionId = new Apple.gsxUserSessionType() { userSessionId = session.userSessionId };
}

Apex Web Service Authentication for .Net CF client

We are developing a barcode application to run on our mobile computers running Windows Mobile 5.0 Pocket PC and it needs to get it's data from our Oracle database.
Apex is already set up but how can I create a secure Web Service using Apex's native Authentication? How to set "HTTPS only"?
Update
I can call the ...?wsdl link in the browser now, looks fine. It's also registered in the project as a WebReferance.
But when I run the following code:
CONTAR_USUARIOSService service = new CONTAR_USUARIOSService();
System.Net.NetworkCredential pocket = new System.Net.NetworkCredential("pocket", "000");
service.Credentials = pocket;
double resultado = service.CONTAR_USUARIOS();
I get this error:
System.Net.WebException was unhandled
Message="WebException"
StackTrace:

at Supernorte.Recebimento.Program.Main()
I get an "Unauthorized" error.
If you get your Oracle inputs and outputs routed through your web service (which I am still personally struggling with), you might be able to access your information that way.
Add the web reference.
It will ask for the URL where your Web Service has been uploaded. I'm guessing this can be a website you own off site, but I use our internal server.
You can see I have a default web page where I load up the available services that I've stuck out there. 1Mainframe.svc` was going to be my "Big Service", but then I realized that I needed to do a lot more than make that once call, so I created the next one, "Erp Service".
Anyway, after I select the ErpService.svc, I'm given this, where I changed the default Web Reference Name to ErpService1. I've personally found that if I need to edit or modify the service, the XML config files get all messed up, so I just delete Service1 and add Service2.
I add a new class called ErpClass1.cs
Add a reference to my Web Service using the namespace for my project, and start coding!
using System;
using System.Linq;
using System.Collections.Generic;
using System.Text;
using AcpMobile5.ErpService1;
namespace AcpMobile5 {
class ErpClass1 {
private ErpService m_erpService;
public ErpClass1() {
m_erpService = new ErpService();
}
public void Query(string woNumber) {
m_erpService.Query(woNumber);
}
public string PartNumber() {
return m_erpService.CoilPartNo();
}
}
}
Obviously, this does not solve everything for you. The Web Service that you use to access your Oracle database still needs to be written, and that's no simple task.
However, I hope it helps point you along the right direction.
This is all done using Visual Studio 2008 for Mobile 5.0.
So, I didn't use Apex as I intended. Instead I enabled Oracle XML DB Native Web Services.
After some hard times with authentication [mostly caused by typing the wrong password ): ] I got this code working:
MyWebService service = new MyWebService();
service.Credentials = new MyWebService("MY_ORACLE_USER", "*******");
double result = service.MY_LOGIN_FUNCTION(this.userName);

Basic Authentication with embedded Jetty 7 server and no web.xml file

I have an embedded implementation of Jetty 7 running as a service and want to add basic authentication with no web.xml file for a servlet.
I created my credentials using the steps described here
I thought that I could create the server, create a security handler with basic authentication and attach a HashLoginService to the security manager. But I am clearly missing several things because I am never getting prompt for credentials.
Below is the code. Any help would be greatly appreciated.
server = new Server(port);
server.addConnector(getSslChannelConnector(securePort));
server.setGracefulShutdown(1000);
server.setStopAtShutdown(true);
// create the context handler for the server
ServletContextHandler sch = new ServletContextHandler(server, WEBAPP_CONTEXT);
// attach the security handler to it that has basic authentication
sch.setSecurityHandler(getSecurityHandler());
// define the processing servlet.
sch.addServlet(new ServletHolder(new ProcessingServlet()), "/process");
.
.
private SecurityHandler getSecurityHandler() {
// add authentication
Constraint constraint = new Constraint(Constraint.__BASIC_AUTH,"user");
constraint.setAuthenticate(true);
constraint.setRoles(new String[]{"user","admin"});
// map the security constraint to the root path.
ConstraintMapping cm = new ConstraintMapping();
cm.setConstraint(constraint);
cm.setPathSpec("/*");
// create the security handler, set the authentication to Basic
// and assign the realm.
ConstraintSecurityHandler csh = new ConstraintSecurityHandler();
csh.setAuthenticator(new BasicAuthenticator());
csh.setRealmName(REALM);
csh.addConstraintMapping(cm);
// set the login service
csh.setLoginService(getHashLoginService());
return csh;
}
private HashLoginService getHashLoginService() {
// create the login service, assign the realm and read the user credentials
// from the file /tmp/realm.properties.
HashLoginService hls = new HashLoginService();
hls.setName(REALM);
hls.setConfig("/tmp/realm.properties");
hls.setRefreshInterval(0);
return hls;
}
I got this working and posted a sample webapp here
The code looks broadly ok.
My interface is slightly different for adding the ConstraintMapping as the single CM add seems have gone in my version of jetty 7.
securityHandler.setConstraintMappings(new ConstraintMapping[] {cm});
Bar that my code is basically identical and does work for me.
Note that once authenticated your browser will not prompt you again unless you restart your browser or follow the instructions here

WebRequest.DefaultWebProxy.Credentials is null and WCF service call fails if I'm behind proxy

I'm behind ISA Server Proxy and I need to call a web service. Given its wsdl I've created proxies (using Add Service Reference command) and have tried to call the service, but it raised an exception telling me that proxy authorization is required. After some research I've found a solution to my problem
var webproxy = new WebProxy(new Uri("http://<address>:<port>").ToString(), true, new string[]
{
})
{
Credentials = networkCredentials,
BypassProxyOnLocal = false
};
WebRequest.DefaultWebProxy = webproxy;
After this piece of code I'm able to call web service. But as I've read here by default DefaultWebProxy uses the same settings as set in IE. However WebRequest.DefaultWebProxy.Credentials is null and I'm unable to pass thru the proxy. Why?
I've was also same boat. The last answer on this post helped me.
How do I determine (elegantly) if proxy authentication is required in C# winforms app
Especially.
//HACK: add proxy
IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
req.Proxy = proxy;
req.PreAuthenticate = true;
//HACK: end add proxy

Sending Cookies over WCF using the ChannelFactory

I use an IOC container which provides me with IService.
In the case where IService is a WCF service it is provided by a channel factory
When IService lives on the same machine it is able to access the same cookies and so no problem however once a WCF Service is called it needs to be sent those cookies.
I've spent a lot of time trying to find a way to send cookies using a channel factory and the only way I could find that works is the following
var cookie = _authenticationClient.GetHttpCookie();
HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();
httpRequestProperty.Headers.Add(HttpRequestHeader.Cookie, cookie.Name + "=" + cookie.Value);
using(var scope = new OperationContextScope((IClientChannel)_service))
{
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;
var result = _service.Add(details);
if (result.Result == RPGResult.Success)
{
return RedirectToAction("Index", "Home", result.Id);
}
}
The problem with me using that method is that I have to know that I'm calling a WCF Service which is not always the case. I've tried writing a wrapper for the ChannelFactory that opens a new operationcontextscope when it creates a new service and various other solutions but nothing has worked.
Anyone have any experience with sending cookies over WCF Services?
I found a solution involving using SilverLight, unfortunately I'm not using silverlight, the solution is here: http://greenicicleblog.com/2009/10/27/using-the-silverlight-httpclient-in-wcf-and-still-passing-cookies/
Unfortunately standard .net doesn't contain the IHttpCookieContainerManager interface
Ideally I would be able to use something similar,i.e. I would be able to tell the channelfactory to pass a cookie whenever it opened.
If anyone has a better way to pass a token that is used for authentication that would be appreciated too.
I have a solution where I create a proxy class of IService and then every time a method on IService is called it invokes the proxy created by the channel factory but the call itself is wrapped in an operationcontextscope just like the one I have in my question.
I used the proxy factory from this link http://www.codeproject.com/KB/cs/dynamicproxy.aspx

Login failed when a web service tries to communicate with SharePoint 2007

I created a very simple webservice in ASP.NET 2.0 to query a list in SharePoint 2007 like this:
namespace WebService1
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
public string ShowSPMyList()
{
string username = this.User.Identity.Name;
return GetList();
}
private string GetList()
{
string resutl = "";
SPSite siteCollection = new SPSite("http://localhost:89");
using (SPWeb web = siteCollection.OpenWeb())
{
SPList mylist = web.Lists["MySPList"];
SPQuery query = new SPQuery();
query.Query = "<Where><Eq><FieldRef Name=\"AssignedTo\"/><Value Type=\"Text\">Ramprasad</Value></Eq></Where>";
SPListItemCollection items = mylist.GetItems(query);
foreach (SPListItem item in items)
{
resutl = resutl + SPEncode.HtmlEncode(item["Title"].ToString());
}
}
return resutl;
}
}
}
This web service runs well when tested using the built-in server of Visual Studio 2008. The username indicates exactly my domain account (domain\myusername).
However when I create a virtual folder to host and launch this web service (still located in the same machine with SP2007), I got the following error when invoking ShowSPMyList() method, at the line to execute OpenWeb(). These are the details of the error:
System.Data.SqlClient.SqlException: Cannot open database "WSS_Content_8887ac57951146a290ca134778ddc3f8" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.
Does anyone have any idea why this error happens? Why does the web service run fine inside Visual Studio 2008, but not when running stand-alone? I checked and in both cases, the username variable has the same value (domain\myusername).
Thank you very much.
Thank you very much for the replies. I'll look into the documents to see how i can change the settings related to the application pool as suggested.
I want to make clear that i wanted to build a webservice to run outside of sharepoint (but can be deployed on the same server with sharepoint).
Is there any way i can programmatically pass the credentials (another domain account instead of 'NT AUTHORITY\NETWORK SERVICE' by default) to sharepoint when invoking OpenWeb method? I believe if i'm able to do that then i can walkaround the security issue above.
When you create your own custom virtual folder and set it inside the IIS, it's highly possible that the user account who run the application pool of that particular IIS virtual directory is currently set to NT authority\Network Service.
You can check carefully, by looking closely of what is the actual application pool that run that particular IIS virtual directory.
From there, you can go to the "Application Pool" folder and right click, choose Properties. Select the "Identity" tab, and it will show you who is the user account that currently running the application pool.
Alternatively, you can refer to the SharePoint SDK, something similar to ExtractCrmAuthenticationToken in dynamics CRM to extract the Authentication Token ticket.
Or alternatively you can use Network Credential to embed your own custom user id and password.
Hope this helps,
hadi teo
I fully agree with Hadi, if this is something you want to just quickly test, for a proof of concept, you can change the credentials under what the Application pool runs, to a user that has permissions. Or you could use Identity Impersonate setting in your config file.
However resist the temptiation to do this in a production enviroment, use the proper authentication. It will come back, to bite you.
If you need to set this up for production, there is a couple of areas that you want to look at, duplicate SPN's, and deligation probably the most common areas that is not configured correctly. Your error however points to impersanation not happening.
Also make sure you are deploying the web service to its own web site that does not already run SharePoint. If you want the web service to run on the same web site as SharePoint read Creating a Custom Web Service.
You can check what application pool identity SharePoint is using by following the same instructions that Hadi writes, but for an app pool running SharePoint. Make sure to only change the application pool used by your web service and not SharePoint or else other permission errors could occur within SP. (There should be no reason but if you are interested in changing the app pool identity used by SharePoint follow these instructions.)
On solution would be to "impersonate" as the SharePoint System account using the following code:
SPSecurity.RunWithElevatedPrivileges(delegate()
{
// also dispose SPSite
using (SPSite siteCollection = new SPSite("http://localhost:89"))
{
using (SPWeb web = siteCollection.OpenWeb())
{
// ...
}
}
});
