14.2 General Procedures for Administering Local User Accounts
In general, administering user accounts on the HP XC system is a 3-step process:
1. As superuser, run the appropriate commands to add, change, or delete a local user account
on the golden client management node (that is, the node that hosts the golden client service).
You can use the standard Linux user commands (useradd, usermod, and userdel) or
use the Network Information Service (NIS) across the system. Editing the appropriate files
manually is not recommended.
2. Transfer the necessary files from the local file system to the image server by way of the
golden client.
3. Propagate this information to all the nodes in the system.
Steps 2 and 3 are discussed in more detail in “Distributing Software Throughout the System”
(page 143).
14.3 Adding a Local User Account
Use the following procedure to add a user account and to propagate that information to all the
nodes in the system:
1. Log in to the golden client node as superuser.
