HP XC System Software Administration Guide Version 4.0

2. Collect as much of the following information about this account as possible:
• Login name
This information is required.
• User's name
• User's password
Note:
A customary practice is to assign a temporary password that the user changes with the
passwd command, but this data must be propagated to all the other system nodes also.
See “Distributing Software Throughout the System” (page 141) for more information.
• User identifier number (UID)
A default value is assigned if you do not supply this information; this value is usually
the next available UID. If you assign a value, first make sure that it is not already in
use.
• Group identifier number (GID)
A default value is assigned if you do not supply this value.
• Home directory
A default value based on the login name is assigned automatically if you do not provide
this information. This home directory must be shared across all the nodes in the HP XC
system.
• Shell
The default value is assigned if you do not supply this information.
• Expiration date
This value specifies when the account will be disabled. Bypassing this entry means that
there is no expiration date for the account.
The date entry must be in the format YYYY-MM-DD.
For more information about these and other commands, see useradd(8).
3. Use the useradd command to add a local user account on the golden client node:
# useradd options name
For example, the following command adds a user named John Adams with the login name
adamsj. This user will be assigned the password temporary, will use the Korn shell, and
will be assigned the home directory /users/adamsj, and default values for the home
directory, UID, and GID.
# useradd -d /users/adamsj -p temporary -s /bin/ksh adamsj
4. Use the procedure in “Distributing Software Throughout the System” (page 141) to transfer
and propagate the files in the necessary files and directories, including the home directory
for the user, the /etc/passwd file, and the /etc/shadow file.
14.4 Modifying a Local User Account
You can change the information for a user account with the usermod command; a user can also
change some account parameters by using the passwd, chsh, and chfn commands on the local
node. For more information on these commands, see the corresponding manpages.
After the information is changed, it does not take effect on all the nodes until the files are
propagated to all nodes in the system.
