Where does Finder keep the sidebar content settings?

I'm trying to resolve a problem where my NAS AFP drive that I usually
drop into "Favorites" in the Finder sidebar won't stick there. Where
are settings for the sidebar kept? They don't seem to be in
com.apple.finder.plist, which is where I'd expect them to be.
