you need to be root to add users - and your web server is most likely not 
runings as root (certainly shouldn't be!!)

To make this work, add the user apache runs under to /etc/sudoers  (look at 
the sudo man page),

then change the command you have to this...

sudo /usr/sbin/adduser -g mel -d /dev/null -s /bin/false -p $pass $usuario


That will use sudo to run adduser as root.

btw - try to only allow sudo access for the apache user, and only to use the 
command adduser (e.g. NOT rm or anything else dangerous..)

Also, make very sure that $paqss and $usuario contain only alphanumeric 
characters; no backticks or quotes or anything.


Hope that helps

Cheers

Shane
