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.

Hi,

I have tried whatever you told me didnt work , and searched internet for the whole weekend. NOTHING.

I was playing with pwconv and pwunconv...a strange thing happened. I have changed permitions on /etd/passwd to 755 and removed /etc/shadow. Now i'm able to run pwunconv. It takes like a couple of seconds, but it wouldnt create any /etc/shadow or smth like that. ????

I appreciate your help, guys.
