[cgiwrap-users] putting root as username

[vinay <vi...@bs...>]

hi all
can i give root as the "username" to any particular CGI script.
Actually i want to add user on a linux system using a web interface. 
And for that i have made a CGI script which calls the system command
"useradd" .But since this "useradd" can be called only through root so 
my CGI script has to be of root user type.

Hence can anybody tell me that can i put root as username.

Regards, 
Vinay
