Generating the CrmService over an IFD Connection

David Fronk of Dynamic Methods Inc. Has figured out how to call the WebService over an IFD. Here is his blog on it.
------------------------------------------
I've been working on an application that needs to connect using the Internet Connector license over an IFD connection. I have users who need to submit data into CRM that are not CRM users and thus have no login credentials. So I started researching using the GUID of a CRM user to authenticate. This is possible with plgins and is utilized for impersonation. However, after a few days of fighting code, authentication errors and discussing options with the MS Support SDK team, we found that authentication tghrough the IFD is not possible by using just a users GUID. There still has to be some level of authentication with Active Directory that must occur and a CRM user's GUID does not contain sufficient information to pass the credential challenge AD requires. IFD requires a username and password in order to instantiate the CRM service.

From what MS Support said, either not many are doing this yet, or I'm one of the few who hadn't figured this out yet.

Either way, I thought I'd share my CRM Service generation code that is used for connecting over an IFD connection Hopefully this helps someone else out, enjoy.

public CrmService IFDConnection(string organization, string server, string domain, string username, string password)
{
// A CrmService reference.
CrmService CrmService = null;
// URL of the Web application.
string WebApplicationUrl = String.Empty;
// GUID of the user's organization.
Guid OrganizationId = Guid.Empty;
//Remove any trailing forward slash from the end of the server URL.
server = server.TrimEnd(new char[] { '/' });
// Initialize an instance of the CrmDiscoveryService Web service proxy.
CrmDiscoveryService disco = new CrmDiscoveryService();
disco.Url = "http://" + server + "/MSCRMServices/2007/SPLA/CrmDiscoveryService.asmx";
//Retrieve a list of available organizations.
RetrieveOrganizationsRequest orgRequest = new RetrieveOrganizationsRequest();
orgRequest.UserId = domain + "\\" + username;
orgRequest.Password = password;
RetrieveOrganizationsResponse orgResponse = (RetrieveOrganizationsResponse)disco.Execute(orgRequest);
//Find the desired organization.
foreach (OrganizationDetail orgdetail in orgResponse.OrganizationDetails)
{
if (orgdetail.OrganizationName == organization)
{
//Retrieve the ticket.
RetrieveCrmTicketRequest ticketRequest = new RetrieveCrmTicketRequest();
ticketRequest.OrganizationName = organization;
ticketRequest.UserId = domain + "\\" + username;
ticketRequest.Password = password;
RetrieveCrmTicketResponse ticketResponse = (RetrieveCrmTicketResponse)disco.Execute(ticketRequest);
//Create the CrmService Web service proxy.
CrmAuthenticationToken sdktoken = new CrmAuthenticationToken();
sdktoken.AuthenticationType = 2;
sdktoken.OrganizationName = organization;
sdktoken.CrmTicket = ticketResponse.CrmTicket;
CrmService = new CrmService();
CrmService.CrmAuthenticationTokenValue = sdktoken;
CrmService.Url = orgdetail.CrmServiceUrl;
WebApplicationUrl = orgdetail.WebApplicationUrl;
OrganizationId = orgdetail.OrganizationId;
break;
}
}
return CrmService;
}
