	are automatically replicated to the other server. In case of conflict, a time stamp is used to
	determine which server holds the most recent version.
multiplexor	The server containing the database link that communicates with the remote server.
N
n + 1 directory	The problem of managing multiple instances of the same information in different directories,
problem	resulting in increased hardware and personnel costs.
name collisions	Multiple entries with the same distinguished name.
nested role	Allows the creation of roles that contain other roles.
network	Network Management Station component that graphically displays information about SNMP
management	managed devices, such as which device is up or down and which and how many error messages
application	were received.
network	See NMS.
management
station
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, filesystems, 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	Red Hat's LDAP Directory Server daemon or service that is responsible for all actions of the

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

	IETF or similar organizations.
	See also OID.
OID	See object identifier.
operational	Contains information used internally by the directory to keep track of modifications and subtree
attribute	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	See PTA.
authentication
pass-through	In pass-through authentication, the PTA directory server will pass through bind requests to
subtree	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.
