deployingradius doc site

Hi! At one point, I found a link to a wonderful page that documents every aspect, in great detail, of configuring a FR server.  Alas, my bookmarks were lost in a crash, and despite an intensive search, I am unable to locate it again, though I believe it was on the deployingradius site.  The wiki doesn't seem to have the detail I need (I'm trying to get a full understanding of how to set up 802.1x), and I recall that document giving that level of detail. Can anyone point me at it? Thanks, -- Jim
