Distinguished name (DN)

An entry's distinguished name uniquely identifies it in the directory. A DN is made up of relative distinguished names

(RDNs). An RDN identifies the entry among the children of its parent entry. For example, in the first image in

LDAP, the RDN for the Ferrari entry is "o=Ferrari".

An entry's DN consists of an entry's RDN followed by the DN of its parent. In other words, it consists of the RDNs for

the entry and each of the entry's parent entries, up to the root of the directory tree. Commas and optional spaces

separate the RDNs. For example, in the first image, the DN for the Ferrari entry is "o=Ferrari, c=Italy".

As with file system paths and URLs, entering the correct LDAP name format is essential to successful search

Note: The RDN is an attribute of a directory entry. The full DN is not. However, you can output the full DN by specifying

"dn" in a query's

returns DNs with spaces after the commas.

A multivalued RDN is made up of more than one attribute-value pair. In multivalued RDNs, a plus sign (+) separates

the attribute-value pairs. In the sample directories, individuals could have complex RDNs consisting of their common

name and their e-mail address, for example, "cn=Robert Boyd + mail=rjboyd@adobe.com".

The concepts of schemas and object classes are central to a thorough understanding of LDAP. The information

provided here does not have detailed descriptions but is enough to use the cfldap tag effectively.

A directory schema is a set of rules that determines what can be stored in a directory. It defines, at a minimum, the

following two basic directory characteristics:

• The object classes to which entries can belong

• The directory attribute types

Object class

Object classes enable LDAP to group related information. Frequently, an object class corresponds to a real object or

concept, such as a country, person, room, or domain, which are all standard object type names. Each entry in an LDAP

directory must belong to one or more object classes.

The following characteristics define an object class:

• The class name

• A unique object ID that identifies the class

• The attribute types that entries of the class must contain

• The attribute types that entries of the class can optionally contain

• (Optional) A superior class from which the class is derived
