HP-UX System Administrator's Guide: Overview

In this way, by configuring printers in one place (the LDAP server), you can
automatically add printers to (or remove printers from) numerous client systems
automatically.
NOTE: Even if a client system is configured to use LDAP-UX and its Printer
Configurator Services, a system administrator can still configure printers in the client’s
spooler manually.

Refer to the following documents for additional information:

on the HP JetDirect Network Interface
• LDAP-UX Client Services B.04.15 Administrator's Guide — for details on configuring
LDAP-UX Client Services and the Printer Configurator Services
Security and Access Control
HP-UX has many tools for securing your servers and data. Threats to your servers and
data can be either malicious or accidental, as well as physical (fires, earthquakes, failing
hardware, and so on). Or, they can be logical (misbehaving software, hacking, and so
on).
For information about the tools available to protect your servers and data against loss
from the threats mentioned previous, see “Data Protection Tools” (page 128).
Controlling Access to Data Using Legacy Unix File Ownership and Privileges
HP-UX has the ability to control access to directories and files using a combination of:
• User and Group ownership of files and directories
• File and Directory mode
Using these, a file or directory is assigned an owner, a group, and an access mask called
a mode, which collectively determine:
Files Who can read, write, or attempt to execute the file.
Directories Who can search the contents of the directory, add files to, remove
files from, or rename files in the directory, and who can cd to the
directory.
There is a lot more to the topic of legacy Unix file ownership and privileges and there
are other, more powerful, mechanisms that allow you to carefully control and monitor
who is accessing the files and directories on your system. An entire volume of the
HP-UX System Administrator’s Guide is devoted to the topic of security. For extensive
coverage of the topic of controlling access to the files and directories of your system
and other security related topics, see HP-UX System Administrator’s Guide: Security
Management.
