You shouldn't really have used such low numbers in the first place, but 
that was your decision.

What if the problem is winbind ?

Right and what happens if your number of AD users grows ? they could 
collide with your local Unix users.

Yes, it may have been best practice in its day (cannot think when, but 
hey) but it is not best practice now and hasn't been for quite sometime.

As for using Linux when it was still not fashionable, well I
A) Remember reading Linus's message shortly after he sent it out (didn't 
really understand what he was trying to get at)
B) Remember booting my first Linux machine from a couple of 3-1/2 inch 
floppies called 'boot' and 'root'

So, don't try and pull the 'I am older than Methuselah' routine :-D
