Thought I'd let you know that comment of yours on Extension talk:CentralAuth inspired me to write a step by step guide :P
I didn't write it for people without root access, since I don't have web hosting without root access. You might want to provide your knowledge? I would think set up w/out root nor any help would be a nightmare!

I am quite surprised that you picked up the message even after >half the year since I posted. I would be glad to help though! :)
