network
management
application
Network Management Station component that graphically displays information about SNMP
managed devices, such as which device is up or down and which and how many error messages
were received.
network
management
station
See NMS.
NIS Network Information Service. A system of programs and data files that UNIX machines use to
collect, collate, and share specific information about machines, users, file systems, and network
parameters throughout a network of computers.
NMS Powerful workstation with one or more network management applications installed. Also network
management station.
ns-slapd HP-UX Directory Server daemon or service that is responsible for all actions of the Directory Server.
See also slapd.
O
object class Defines an entry type in the directory by defining which attributes are contained in the entry.
object identifier A string, usually of decimal numbers, that uniquely identifies a schema element, such as an object
class or an attribute, in an object-oriented system. Object identifiers are assigned by ANSI, IETF
or similar organizations.
See also OID.
OID See object identifier.
operational
attribute
Contains information used internally by the directory to keep track of modifications and subtree
properties. Operational attributes are not returned in response to a search unless explicitly
requested.
P
parent access When granted, indicates that users have access to entries below their own in the directory tree
if the bind DN is the parent of the targeted entry.
pass-through
authentication
See PTA.
pass-through
subtree
In pass-through authentication, the PTA directory server will pass through bind requests to the
authenticating directory server from all clients whose DN is contained in this subtree.
password file A file on UNIX machines that stores UNIX user login names, passwords, and user ID numbers. It
is also known as /etc/passwd because of where it is kept.
password policy A set of rules that governs how passwords are used in a given directory.
PDU Encoded messages which form the basis of data exchanges between SNMP devices. Also protocol
data unit.
permission In the context of access control, permission states whether access to the directory information is
granted or denied and the level of access that is granted or denied.
See also access rights.
pointer CoS A pointer CoS identifies the template entry using the template DN only.
presence index Allows searches for entries that contain a specific indexed attribute.
protocol A set of rules that describes how devices on a network exchange information.
protocol data unit See PDU.
proxy
authentication
A special form of authentication where the user requesting access to the directory does not bind
with its own DN but with a proxy DN.
proxy DN Used with proxied authorization. The proxy DN is the DN of an entry that has access permissions
to the target on which the client-application is attempting to perform an operation.
PTA Mechanism by which one Directory Server consults another to check bind credentials. Also
pass-through authentication.
