I would be *very* interested in that script, Rowland.  I have been 
unable to get a member server to work with any form of ADDC, and I've 
been trying for a week.  Just crashed out last night with Louis' script 
(both automated, and me working through it step by step).

What version of samba is in the backports?

and as a side note to Bob -- If I open the script directly from the 
website using gedit to open it from firefox (on a different, older 
ubuntu machine) I get all the correct formatting (I spent several hours 
working through it and all its assumptions, yesterday).  But I haven't 
looked at it with vi. Maybe I will.  maybe the sed command is showing up 
here broken incorrectly because of word-wrap in your newsreader client?
