I am just trying to consuming a web service in remote computer using windows authentication however login credentials are different in local & remote computer.
Code Snippet:
Dim objproxy As New WebReference.Service1
'Create a new instance of CredentialCache.
Dim mycredentialCache As CredentialCache = New CredentialCache()
'Create a new instance of NetworkCredential using the client
Dim credentials As NetworkCredential = New NetworkCredential("username", "pwd","domain")
'Add the NetworkCredential to the CredentialCache.
'mycredentialCache.Add(New Uri(objproxy.Url), "Basic", credentials)
objproxy.Credentials = credentials
It is timing out but when i use
mycredentialCache.Add(New Uri(objproxy.Url), "Basic", credentials)
I get "401 Unauthorized" message,
Please assist.
You want windows authentication so use:
mycredentialCache.Add(New Uri(objproxy.Url), "Negotiate", credentials)

I am trying to call CRM webservice from my custom WCF service. And I am getting the exception "The caller was not authenticated by the service". Checked the authentication mode in IIS (where my wcf service is hosted). Its set to anonymous authentication enabled.
Is there any reason why MSCRM service would fail authentication while call is made from WCF?
Here is my code which calls the CRM web service
OrganizationService service;
var crmConnection = CrmConnection.Parse("Server=http://myserver/orgname; Domain=domainname; Username=username; Password=passwordtext");
service = new OrganizationService(crmConnection);
Entity crmEvent = service.Retrieve("new_event", eventId, new ColumnSet("status"));
When using windows authentication you need to pass a Networkcredential to the constructor of the OrganizationService.
This was already answered by #Daryl here.
I have problem with web service I want to connect to.
In soapUI i used basic authentication with username and password (domain empty), and changed WSS-Password Type to PasswordText and I could without a problem connect to web service. But when I try to connect using c# code:
WebService service = new WebService();
service.ClientCredentials.UserName.UserName = "user";
service.ClientCredentials.UserName.Password = "pass";
service.SomeMethod();
It returns "Forbidden" error.
I'm having a small issue with implementing custom basic authentication for a asmx in .net 4.0.
I've created the HttpModule which would start the authentication process of the web service consumer runnig this code,
HttpApplication application = (source as HttpApplication);
HttpContext context = application.Context;
if ( VirtualPathUtility.GetFileName(context.Request.FilePath).Contains("svcEWS.asmx"))
{
string username = "", password = "";
string authHeader = HttpContext.Current.Request.Headers["Authorization"];
if (!string.IsNullOrEmpty(authHeader) && authHeader.StartsWith("Basic"))
{
//Authenticate here
}
}
However there is no authentication header present whenever this code is reached.
The consuming web app is simply calling,
EWS.svcEWS svcEWS = new EWS.svcEWS();
svcEWS.Credentials = new NetworkCredential("admin", "admin", "example.com");
svcEWS.HelloWorld();
IIS is set to run with anonymous authentication to anonymous authentication to prevent it from catching any auth requests.
Is there something I'm missing to have the client pass the correct header to my module?
I was forgetting to reject the first request with 401 code to force authentication. Doing so fixes the problem, as the invoker re sends the request with the auth header.
I have web service, which use integrated security in IIS.
Now, I want to test my web service.
I created a console application and adding web reference.
now, when i m trying to use web method. It show 401 error.
m i missing any authentication.
I think i need to pass user name and password programatically.
can anyone direct me in right direction.
Set the web service credentials to the System.Net.CredentialCache.DefaultCredentials in your console app
MyWebService proxy = new MyWebService();
proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
Edit
pass credentials programmatically:
MyWebService proxy = new MyWebService();
proxy.Credentials = new System.Net.NetworkCredential("username", "password", "domainname");
You need to add your windows id on your desktop to the allowed users in IIS.
my code is providing an access to our web service.
WebProxy proxy = new WebProxy(ProxyURL, ProxyPort);
proxy.UseDefaultCredentials = false;
NetworkCredential nc = new NetworkCredential( ProxyLogin, ProxyPassword);
proxy.Credentials = nc;
myWebService.Proxy = proxy;
My problem is that customer doesn't know ProxyLogin and ProxyPassword, especially if he is running Microsoft ISA server. Company policy doesn't allow him to know password and login.
Is there anyway to reach authorization information by code?
There is no way to get password by code. If there was a way it would be a security vulnerability.
The user should have proxy access for his account. If he don't have, Than this is the end of it. If he has proxy access than your application should use his credentials.
proxy.UseDefaultCredentials = true;
