Package org.ldaptive.dn

Class Dn

java.lang.Object

org.ldaptive.dn.Dn

public class Dn
extends Object

Distinguished name containing zero or more relative distinguished names. RDNs are ordered from left to right such that the left-most RDN is considered the first. For the DN 'cn=Jane Doe,ou=People,dc=ldaptive,dc=org', the first RDN is 'cn=Jane Doe'. See RFC 4514 for more details on the string representations of DNs.
