For those of you who are having trouble authenticating private community RSS feeds please see the steps below.
1. Download any RSS reader that will authenticate an RSS feed URL. (I'm using Feedreader.)
2. When entering your username make sure you are using your Community ID and not your email address as we are authenticating through Jive and not VMware.com.
3. Your password should be the same password as used to login to Communities.
Hope this helps!
