I'm trying to access an RSS feed that has an https: url and requires authentication. This doesn't seem to work with the Zimbra web client. After I enter the url, I get a "Critical Error": "Content could not be retrieved. Make sure the following URL is a RSS/ATOM feed:" followed by the url. It does not request authentication. I'm using FireFox 1.5 with network release 3.0, I believe.
Please note that this RSS feed does work with Thunderbird, and http: RSS feeds work with the Zimbra client.
Any suggestions? I couldn't find any relevant info in the Forums or Bugzilla. Should I file this in Bugzilla?
