Changing Root's Password

When changing root's password, you must always run chkey -p immediately after changing the password with the passwd command. Failure to run chkey -p after changing root's password will result in root being unable to properly log in.

To change a root password, follow these steps:

1. Log in as root.

2. Change root's password using passwd.

   Do not use nispasswd.

3. Run chkey -p.

   You must use the -p option.
