Firefox or Chrome users are repeatedly prompted for credentials in Microsoft Dynamics CRM 2011

Some Firefox or Chome users are repeatedly prompted to sign in even though they have successfully signed in previously when they use the web browser.

This issue occurs when the following conditions are true:

  • The web browser is connecting to a Microsoft Dynamics CRM Server that uses AD FS 2.0 for claims-based authentication. Claims-based authentication is required for an Internet-facing deployment (IFD).
  • The web browser that used to access Microsoft Dynamics CRM 2011 is Firefox or Chrome.

This issue occurs because of the Windows operating system feature Extended Protection for Authentication. For more information about this security feature, see Microsoft Security Advisory (973811)
