ERROR: /usr/local/cpanel/scripts/realchpass
Invocation changes only the system
password and does not have any effect
on other services associated with your
cPanel account, including FTP, SSH,
WebDAV, and FrontPage.  It is strongly
encouraged for you to change the
password via the WHM & cPanel
interface. You can force a password
change through this script by setting
the environment variable
‘ALLOW_PASSWORD_CHANGE=1′.

You can fix the above error by running the following command. After that execute the script again.

# export ALLOW_PASSWORD_CHANGE=1
