Is there a standard that defines how news aggregators should request
access to web feeds behind a login/password?

Our few private groups - http://forums.e-democracy.org - generate web
feeds which may be read by default browser-based feed readers and
there is no problem display them if someone stays logged in via the
browser.

However, I'd like to have the developer of the open source GroupServer
- http://groupserver.org - tool explore giving authenticated access to
Bloglines and other users of aggregators that supposedly support this
kind of access.
