How to verify all user home directories are writable only by their owner

1. The problem statement, all variables and given/known data:
Need to verify that all user home directories are writable only by their owner on Solaris. The script posted below is workable but it is taking a long time to display the results, and I don't seem to be able to fix it or find any alternative way to it.

2. Relevant commands, code, scripts, algorithms:
My friend says it's the `su - $i -c "ls -ld" 2> /dev/null | grep ^d | awk '{print $1}'` part that is causing the problem but his not sure what to do either.

3. The attempts at a solution (include all code and scripts):

Code:

#!/usr/bin/bash
clear
echo " Verifying if user home directories are writable only by their owner"
echo

TEMPFILE=/permgrep.txt
TEMPFILE2=/namegrep.txt
accno=0
h=1
no=1
Ps=0
Fs=0

if [ ! -f ${TEMPFILE} ]
then 
touch ${TEMPFILE}
fi

if [ ! -f ${TEMPFILE2} ]
then 
touch ${TEMPFILE2}
fi

ACCOUNTS=`cat /etc/passwd | awk -F: '{print $1}'`
array=($ACCOUNTS) 

for i in "${array[@]}"
do
let "accno += 1"
PRINTER=`su - $i -c "ls -ld" 2> /dev/null | grep ^d | awk '{print $1}'`
if [ -n "$PRINTER" ]
then
echo $PRINTER >> $TEMPFILE
echo $i >> $TEMPFILE2
fi
done

echo

for line in $(cat /permgrep.txt)
do

READTF2=`head -$h /namegrep.txt | tail -1`

if [ $line == 'drwxr-xr-x' ]
then
echo $no"-"$READTF2": PASS"
let "h += 1"
let "Ps += 1"

else
echo $no"-"$READTF2": FAIL"
let "h += 1" 
let "Fs += 1"
fi

let "no += 1"

done

nohodi=`expr $accno - $Ps - $Fs`

echo "   Total user accounts: "$accno
echo "   Pass: "$Ps
echo "   Fail: "$Fs
echo "   no home directory : "$nohodi

rm /namegrep.txt
rm /permgrep.txt

createhomedir

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME

     createhomedir -- create and populate home directories on the local computer.

SYNOPSIS

     createhomedir [-scbalh] [-n directoryDomainName] [-u username]

DESCRIPTION

     createhomedir provides several options for creating and populating home directories.

OPTIONS

     -s       creates home directories for server home paths only (default).

     -c       creates home directories for local home paths only.

     -b       creates home directories for both server and local home paths.

     -a       creates home directories for users defined in all directory domains of the server's search path.

     -l       creates home directories for users defined in the local directory domain.

     -n directoryDomainName
	      creates home directories for users defined in a specific directory domain in the server's search path.

     -u username
	      creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a,
	      -l, and -n parameters when you use the -u parameter, -a is assumed.

     -i       reads username list from standard input and creates specified home directories. Each username should be on its own line.

     -h       usage help.

FILES

     /usr/sbin/createhomedir			   location of tool

CAVEATS

     When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible
     home directories from being created. In this case, you may need to specify the usernames explicitly.
