Useradd issue
Hi all,

I'm using Red Hat Enterprise Linux Server release 5 (Tikanga)

I have a query regarding adding users, I have a requirement of creating multiple users at one go.
In order to do so I have written a shell script which would create a user and set the password at one go.
Now the problem is

1] Setting password.

I have tried two approcahes

Code:
password=`echo "PASSWORDSTRING"|md5sum`

useradd -p $password $username

and

Code:
pass=$(perl -e 'print crypt($ARGV[0], "password")' $password)

useradd -p $pass $username

In both the cases I'm able to create user without a problem.How ever when i try to login as the user Im unabel to as the password is in correct.

Following is the script

Code:
if [ $(id -u) -eq 0 ]
then
cat /root/newlis|while read IN
do
        username=`echo $IN|awk -F ":" '{print $2}'`
        password=`echo $IN|awk -F ":" '{print $3}'`
        egrep "^$username" /etc/passwd >/dev/null
if [ $? -eq 0 ]
then
echo "$username exists!"
exit 1
else
pass=$(perl -e 'print crypt($ARGV[0], "password")' $password)
useradd -m -p $pass $username
grep "$username" /etc/passwd >/dev/null 2>&1
if [ $? -eq 0 ]
then
echo "User $username added" >> /root/user.log
else
echo "Problem adding $username"
fi
fi
done
else
echo "Only root may add a user to the system"
        exit 2
fi


Please suggest.

Thanks and Regards
Syed

Well ,the intresting thing is the passwords are valid as I m doing as follows

I m logged in as root so I am

Code:
su - newuser

passwd

it asks me for old pasword and then lets me change the pasword without any errors.Which means the password assigned by the script is OK ,its only that iam unable to login for some reason.

SYNTAX

       partimaged-passwd [-Dhl] username password

       database  this tool was written. It allows to easily add and remove users or list the users in the database. All users in this database are
       allowed to access the partimaged server.

OPTIONS

       -D username
	      Delete the specified user from the password file.

       -l     List users in password file and exit.

       -h     Output help information and exit.
