if you see this error then just run the "pwconv" from root prompt as shown in the example and  you will be all set.

[root@aqua ~]# passwd myuser
Changing password for user myuser.

  4. If you still can not lock /etc/passwd then try this:

    1. mount -o remount,rw /
    2. chmod 640 /etc/shadow
    3. pwconv

    After this, you should be able to reset passwd.
