Is anonymous authentication required on the CRM 2011 website?

  After disabling anonymous access on the CRM website I see an error in the event log when an application attempts to use the organization service. The application receives a 500. Enabling anonymous access solves the issue. This deployment in on-premises and not IFD.
  
  Is there any information available on anonymous access requirements and CRM 2011? The only documents I found deal with the CRM 4.0 Outlook client accessing CRM 2011 or IFD.
  

   

  Error Details from Event Log:
