An Internet Domain Naming System (DNS) service provider is part of J2SE 1.4.0. This component enables applications to read data that is stored in the DNS.
The JNDI Lightweight Directory Access Protocol (LDAP) service provider has security enhancements that enable applications to establish secure sessions over existing LDAP connections and to use different authentication protocols.
