Passing password in script for ssh connection - no except
Used the script posted on forum - unix.com/shell-programming-scripting/21597-script-change-passwords-same-user-multiple-servers.html but the last question posted on this seems to be still unanswered, tried different things with no success, can someone help giving an way to pass the password via script for ssh connection. Using except is not an option. We have more than 300 servers and need to setup an script to change password. Also setting up ssh public keys for password less communciation is not an option with these limitation, I am using following code, but it just waits on the password prompt. can someone help?
Code:
#! /usr/bin/ksh
DELAY=4
stty -echo
print -n Enter Old Password-
read OLDPASS
print
print -n Enter New Password-
read NEWPASS
print
stty echo
USER=$(whoami)
exec 4>&1
prog=${0##*/}
progdir=$(dirname $0)
for HOST in $( cat "$progdir/.servers" ) ; do
     ssh -T -oPreferredAuthentications=password $HOST >&4 2>&4 |&
     sleep $DELAYprint -p $OLDPASS
     sleep $DELAY
     print -p touch changepassdatafile.$HOST
     sleep $DELAY
     print -p exit
     wait
done

nwpjmv

NWPJMV(1)							      nwpjmv								 NWPJMV(1)

NAME

       nwpjvm - Move print job to Unix queue

SYNOPSIS

       nwpjmv [ -S server ] [ -h ] [ -U user name ] [ -P password | -n ] [ -C ] [ -q queue name ] [ -c command ] [ -j job number ] [ -d ]

DESCRIPTION

       nwpjmv is a program that connects to print queues on NetWare servers and moves a designated print job to a Unix queue.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the print server name at the server.

       -P password
	  password  is the password to use for the print server at the server. If neither -n nor -P are given, and the user has no open connection
	  to the server, pserver prompts for a password.

       -n
	  -n should be given if the print server does not require a password.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -q queue name
	  queue name is the name of the print queue you want to service.

       -c command
	  nwpjmv  removes  the designated job from the Novell queue and feeds the job file to stdin.  command is the printing command that is exe-
	  cuted for each job. The default command is 'lpr'.

	  You can insert several flags into the command, preceded by %. These are replaced with values retrieved from the queue structure for  the
	  print job.

	  %u: This field will be replaced by the name of the user who posted this print job.

	  %d: This field will be replaced by the job description field of this print job.

       -j job number
	  This designates the ID number of the print job to be moved.

       -d causes extra error messages to be logged.
