Can I use the Dynamics CRM 4.0 SDK against a hosted IFD system?

I am running this code (with names and security details obscured). When I do, I get 401 unauthorised. The credentials are that of the user on the hosted server. Is this possible against an IFD system?

var token = new CrmAuthenticationToken(); token.AuthenticationType = 0; token.OrganizationName = "myorganisation";

    CrmService service = new CrmService();
    service.Url = "https://myorganisation.dynamicsgateway.com/mscrmservices/2007/crmservice.asmx";
    service.CrmAuthenticationTokenValue = token;
    service.Credentials = new NetworkCredential("bob.smith", "Password", "HOSTEDCRM");

    var request = new RetrieveMultipleRequest();
    request.Query = new QueryExpression
    {
        ColumnSet = new ColumnSet(new string[] { "name" }),
        EntityName = "account"
    };
    var response = servi开发者_Python百科ce.Execute(request);

I assume this code is outside of the CRM Website? In that case you'll want to add a reference to the discovery service as Mercure points out above. You'll want to execute a RetrieveCrmTicketRequest against the discovery service to get a ticket good for connecting to the Crm Services.

In your CRM Authentication Token you'll want to set the authentication type to 2 (IFD). Then set the CrmTicket property on the token to the ticket you got from your RetrieveCrmTicketResponse.

I also set the URL based on that response, but you could continue to hard code it.

You will want to continue to set the Credentials on the service.

I use a single user to connect to CRM and cache that ticket (an expiration date is in the response from the discovery service). That way I can bypass the discovery service on future requests. There is an error code to look for to go after the ticket again, but I don't have it off hand.

Yes, it's possible, you are only missing a little pieces, the CrmAuthenticationToken.ExtractCrmAuthenticationToken.
