Displaying a PKI-protected RSS feed within Sharepoint

Question

I'm trying to create a "heartbeat" page in WSS 3.0 that displays multiple RSS feeds from a number of different non-sharepoint sites within our corporate intranet. Thanks to the help I received here: Viewing an RSS feed within Sharepoint Services 3.0 , I was able to get most of the feeds to display.

However, a couple of these RSS feeds require PKI authentication (they verify you have the right access to view them). If I use the same method (XML viewer web part with XLS formatting), Sharepoint errors out on the RSS pull since it's not passing a certificate.

How can I configure Sharepoint to pass a certificate for these pulls? Preferably I'd like it to pass the user's own cert, but it might also be okay if it just passes a specific server-owned cert.

Thank you!

Answer 1

Authenticated feeds have been an issue from the begining for the web parts provided with SharePoint. Unless you resort to either buying one the enables you to provide/store credentials, or develop your own, you could use search federation capabilities to read external feeds which have the increased advantage of allowing to connect.
