STEP 2 : Creating a new default authenticator

            cd ../security

            mv DefaultAuthenticatorInit.ldift oldDefaultAuthenticator

            java weblogic.security.utils.AdminAccount weblogic mynewpassword .

   # (Replace mynewpassword with your new password  and do not forget the space between your password and dot)

STEP 3 :  Removing boot.properties file if exists
