LDAP Glossary


Each LDAP entry consists of a number of named attributes, each of which has one or more values.

Also, the N2L service mapping and configuration files each consist of a number of named attributes. Each attribute has one or more values.


The DN where part of the DIT is rooted. When this is the baseDN for an NIS domains entries it is also referred to as a context.


For the N2L service, a context is something under which a NIS domain is generally mapped. See also baseDN.

custom map

Any map that is not a standard map and therefore requires manual modifications to the mapping file when transitioning from NIS to LDAP.


An LDAP directory is a container for LDAP objects. In UNIX, a container for files and subdirectories.

directory cache

A local file used to store data associated with directory objects.

directory information tree (DIT)

The DIT is the distributed directory structure for a given network. By default, clients access the information assuming that the DIT has a given structure. For each domain supported by the LDAP server, there is an assumed subtree with an assumed structure.


See directory information tree.


A single row of data in a database table, such as an LDAP element in a DIT.


Lightweight Directory Access Protocol is a standard, extensible directory access protocol used by LDAP naming service clients and servers to communicate with each other.

mapping file

The NISLDAPmapping file that establishes how to map entries between NIS and LDAP files.


A description of where to look for a given attribute in the DIT. The searchTriple is composed of a base dn, scope, and filter. This is part of the LDAP URL format as defined in RFC 2255.
