LangID: See primary language identifier.
language code identifier (LCID): A 32-bit number that identifies the user interface human language dialect or variation that is supported by an application or client computer.
language identifier: See language code identifier (LCID).
LDAP: See Lightweight Directory Access Protocol (LDAP).
LDAP connection: A TCP connection from a client to a server over which the client sends Lightweight Directory Access Protocol (LDAP) requests and the server sends responses to the client's requests.
Lightweight Directory Access Protocol (LDAP): The primary access protocol for Active Directory[MS-ADTS]. LDAP is an industry-standard protocol, established by the Internet Engineering Task Force (IETF), which allows users to query and update information in a directory service (as specified in [MS-ADTS]).
lingering object: A domain controller (DC) that was offline for longer than the value of the tombstone lifetime can contain objects that have been deleted on other domain controllers (DCs) and for which tombstones no longer exist.
link: When the value of an attribute refers to a directory object, and the attribute's Attribute-Schema object has an even value for attribute linkId, then that attribute value is a link. Sometimes referred to as a forward link.
link value: The value of a link attribute.
LinkValueStamp: The type of a stamp attached to a link value.
list data region: A report item on a report layout that displays data in a list format.
listening state: A server or proxy state in which the server or proxy is able to accept and respond to events coming from the network.
little-endian: Multiple-byte values that are byte-ordered with the least significant byte stored in the memory location with the lowest address.
LM hash: A DES-based cryptographic hash of a clear text password.
local area network (LAN): A group of computers and other devices dispersed over a relatively limited area and connected by a communications link that enables any device to interact with any other device on the network.
local area network adapter (LANA): (1) A hardware device that facilitates network communication via support of the first two levels (physical and datalink) of the ISO OSI standards, providing physical network access and low-level addressing capability through MAC addresses.
(2) In NetBios-specific implementations, a number that is used to identify the network adapter to which NetBIOS is bound.
local change order: A change order that is created because of a change to a file or folder on the local server. The local server becomes the originator of the change order and constructs a staging file.
local domain controller (DC): A domain controller (DC) on which the current method is executing.
local master browser: The browser on a given subnet that was elected to maintain the master copy of information related to a given domain. That is, different domains have different local master browsers on the same subnet.
local master browser server: A server that is elected master browser server on a particular subnet across a domain.
local maximum: A pair consisting of an offset i in a file and the hash value h(bi-Hash Window .. bi) that has the property that for all j ≥ 0, such that i - horizon ≤ j ≤ i + horizon, j = i OR h(bj-Hash Window .. bj) < h(bi-Hash Window .. bi), where for all k < 0, bk is defined to be 0. Local maxima are used to find cut points by the remote differential compression (RDC) FilterMax algorithm.
Local Security Authority (LSA): A protected subsystem that authenticates and logs users onto the local system. LSA also maintains information about all aspects of local security on a system, collectively known as the local security policy of the system.
Local Security Authority (LSA) database: A Microsoft-specific terminology for the part of the user account database containing account privilege information (such as specific account rights) and domain security policy information.
local security policy: A collection of security settings present on a machine that affects how that machine regulates access to the resources it provides.
locale ID: See language code identifier (LCID).
localizable: Anything that is specific to a language or country.
localizable information: The portion of information in a Common Information Model (CIM) class definition that could be specific to a language or country.
locally unique identifier (LUID): A 64-bit value guaranteed to be unique within the scope of a single machine.
(2) In the context of domain controllers (DCs), the functionality encompassed by the DC Locator Protocol. In a broader context, the cooperative function between clients and DCs, which allow clients to locate the nearest DC that offers particular feature services.
locked partition: A partition that is inaccessible.
logical cluster number (LCN): The cluster number relative to the beginning of the volume. The first cluster on a volume is zero (0).
logical connection: The state maintained on client and server in association with a connectionId.
Logical Disk Manager (LDM): A subsystem of Windows that manages dynamic disks. Dynamic disks contain a master boot record (MBR) at the beginning of the disk, one LDM partition, and an LDM database at the end. The LDM database contains partitioning information used by the LDM.
logical partition: See logical drive.
logical unit number (LUN): A number that is used to identify a disk on a given disk controller.
Lost and Found container: A container holding objects in a given naming context (NC) that do not have parent objects due to add and remove operations that originated on different domain controllers (DCs). The container is a child of the NC root and has RDN CN=LostAndFound in domain NCs and CN=LostAndFoundConfig in config NCs.
