title: "the user authentication failed!" error while accessing Discovery.svc using CRM 2011 XRM
body: <p>I am writing a .NET website which is accessing CRM dynamics.</p>
  
  <p>I have setup the website on IIS, and impersonated the CRM user so that the website runs in the context of CRM accessible user.</p>
  
  <p>The same code was working fine when the site was pointing to demo CRM Dynamics portal
  I have deployed the site on another server, and now pointing to live CRM dynamics portal, and I got stuck up at "The user authentication failed!" error.
  Few things I can confirm is - 1) Impersonated user has access to CRM Dynamics. 2) OrgnaizationName is correct.
  The .NET Site is consuming Discovery.svc to access CRM Dynamics</p>
