Error - The RSS webpart does not support authenticated feeds

'The RSS webpart does not support authenticated feeds'

I encountered this error when I tried to use SharePoint 2010 RSS Viewer Web Part with internal feed (It does not happen with 3rd party feeds)

I had to change authentication provider settings from NTLM to Kerberos. To do this, go to SharePoint Central Administration and click on the Application Management tab. Within the list of options, click on Authentication Providers. Click on Default (should be the only one listed if you are an 'out of the box' set-up). Under IIS Authentication Settings, the checkbox for Integrated Windows authentication should be selected. Change the radio button selection from NTLM to Negotiate (Kerberos). Click Save. If you go and refresh the page containing the RSS Viewer web part, the feed should now be displayed, i.e. it worked for me.



  1. Hi thanks for the post, didnt you also have to setup the SPNs for the service accounts and configure IIS?

  2. Then you did it wrong. This will cause problems for you in the long run
