[X-Unix] Creating users with the command line

[Pedro fp]

G'day Folks

I'm trying to (re)configure the Apache server in my Mac OS X.3  
following the instructions given in "Apache the Definitive Guide"  
(O'Reilly). I'm doing this both as a learning exercise and because I  
need a more sophisticated testing server than I currently have, in  
particular I need multiple virtual servers with SSL.

Early on ATDG advises creating a user called 'webuser' in a group  
'webgroup'. The authors advise first creating webgroup using the  
command ...
	adduser -group webgroup
then using addgroup to add webuser however when I attempt to run those  
commands I get ...
	-bash: adduser: command not found
Can anyone advise how I can do this on OS X.3? The objective is to  
create a user who "cannot actually log in" for Apache services to run  
as.
	

Cheers, Pedro :-)
