thanks to ian.mcgingley at axa-tech.com.au from actually sending a
script, and giving me some ideas.

NOTE: puting all the password in a spread*** is a great securuty risk,
and has been noticed.

the solution is divided in two parts

1.- the spread*** must be saved in a csv file (coma separated values,
without double quotes " )

2.- two scripts, 1 in shell to get the useradd bin working and another
using expect to get the password.

here are the two scripts.

put_passwd.expect

#!/opt/sfw/bin/expect
if $argc<2 {
        send_user "$argv0: missing parameters\n"
        exit }
set username [lindex $argv 0 ]
set password [lindex $argv 1 ]
spawn passwd $username
expect "ew Password:"
send "$password\r"
expect "ew Password:"
send "$password\r"
expect "#"
exit

the putuser.sh which call the first one.

#!/bin/bash
FILEIN=$1
SGID=100
USERSHOME=/export/home/users
USERSSHELL=/bin/false
USRCRTLOG=/var/log/usercreation.log
IFS=,
cat $FILEIN | while read internalvalue comentario password userid
anotherdata
do
   useradd -g $GID -c "$comentario $internalvalue " -d
$USERSHOME/$userid -s $USERSSHELL -m -k /etc/skel $userid 2> $USRCRTLOG
   ./put_passwd.expect $userid $password 2>> /var/log/useradd.log
done
