There are several issues in the script.  I took a stab at a few below.  I
haven't put in the sudo code as I am not a proponent of including passwords
in script files.  You may want to have a public/private key pair between the
two root id's on both machines.  That would require you to have a key
without a passphrase, which, for root, is not ideal either.

I'll let the security gurus handle that one.

Here is a draft script rewritten:

--- Start of script ---
#!/bin/bash

echo "Checking for user file..."
if [[ ! -e /home/dj/list ]]
then
	echo "User file not found" >& 2
	exit 1
fi

echo -n "Enter Hostname: "
read HOST

3</home/dj/list

while read -u 3 USER GROUP PASSWORD FULL NAME
do
	ssh $HOST ...
	...
done
--- End of script ---

Hope this helps,
Michael
