I was trying to construct a demo to show someone building up a My Site and sucking information from SharePoint List RSS feeds from various team sites. To my horror I got the error message "The RSS webpart does not support authenticated feeds."
So does this mean that you can’t consume RSS feeds from within it’s own SharePoint environment or any authenticated source?
There seems to be plenty of posts confirming my issue here furthermore it is confirmed that it will only work if Kerberos authentication is configured on the server.
Some people have recommended using another webpart akak the SharePoint 2007 RSS Aggregator Tool. Something else to experiment with. Someone has put together a good initial review of this. He’s just updated it too!
