And there are even more that think that making the Windows 'super' user 
into a standard Unix user is a bad idea and could lead to even more 
security problems. If you are having problems with Administrator being 
mapped to the Unix user root, then you are doing something wrong.

I keep looking at your bug report and thinking that I should just close 
it as being 'invalid', but I just ignore it in the end.

It has been common practice to map Administrator to root for years, even 
before the advent of Samba AD and I haven't seen any mention of a 
related security problem.
