title: Microsoft CRM 2011 cross domain authentication
body: <p>We are creating a separate web site whose contents will mashup with a Microsoft CRM installation through various iframes.  Our plan is to utilize Integrated Windows Authentication with our web site and pass credentials to an OrganizationServiceProxy to access CRM.  However, for IFD (Internet Facing Deployment) we aren't clear on how this would work.</p>
  
  <p>In CRM 2011 how do you map a user that authenticates through IFD to a proper active directory user that can be used to authenticate into the CRM service endpoint?</p>
  
  <p>Any sample/pseudo code would be much appreciated!</p>
