There might be a need to Change SUDO LDAP password whilst managing the SUDO rights centrally through IDM. In this scenario it would be the 1st time you are configuring the SUDO rights. Follow the steps outlined to change the password for master server.

NOTE: Don't run this on replica instances of IDM as it would be replicated from Master.
