You will probably need to script using a for loop and awk to get the format of the /etc/shadow file correct.
1) awk -F: ' { print $1 }' < /etc/passwd > user.ids
Depending on the layout, you may need addl data from the passwd file to properly create the shadow file.
2)
for name in 'cat user.ids'
do
awk '{ print $name "put your shadow format here" }' >> shadow.out
done
Something like this may solve your problem. Just make sure that you can duplicate the format of the /etc/shadow file.
IF ALL ELSE FAILS...
You may need to go to the RedHat site and search for conversion from an OS without a shadow file to an OS version with /etc/shadow implemented.

pwconv
pwconv(1M) System Administration Commands pwconv(1M) NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
