Most organizations require at least one root user role definition that is equivalent to specifying ALL:ALL in a sudoers file or giving users access to the root password on their computers. The purpose of this role definition is to allow selected users to execute privileged commands on a regular basis. The role definition allows them to execute commands without being given the root password or having privileges hard-coded in individual sudoers files on multiple computers.
Because this role definition enables system administrators to execute privileged commands without the root password, you can improve security for the organization and reduce the chance of an audit finding for access to the root password.
You can create this role definition in a parent zone or a child zone to control its scope. In most cases, you should only assign the role in a child zone or on an individual computers.
