Root users are governed by the Root Password Policy and by default, their passwords never expire. However, if a root user's password must be changed, use the ldappasswordmodify tool.
  1. Open a text editor and create a text file containing the new password. In this example, name the file rootuser.txt. 
    $ echo password > rootuser.txt
  2. Use ldappasswordmodify to change the root user’s password. 
    $ bin/ldappasswordmodify --port 1389 --bindDN "cn=Directory Manager" \
--bindPassword secret --newPasswordFile rootuser.txt
  3. Remove the text file. 
    $ rm rootuser.txt
