Each object in the namespace may have attributes that can be used to search for the object. Each LDAP entry contains a name and a set of attributes, as well as an optional set of child entries. An LDAP entry's attributes are represented by the Attributes interface, whereas individual attributes are represented by the Attribute interface. As a result of federation, the names that you supply to the JNDI's context methods can span multiple namespaces. These are called composite names.

Different versions of the LDAP support different types of authentication. The LDAP v2 defines three types of authentication: anonymous, simple clear-text password , and Kerberos v4. It specifies a challenge-response protocol in which data is exchanged between the client and the server for the purposes of authentication and establishment of a security layer on which to carry out subsequent communication.

The authentication mechanism is specified by using the Context. The property may have one of the following values. If the client does not specify any authentication environment properties, then the default authentication mechanism is "none". The client will then be treated as an anonymous client. If the client specifies authentication information without explicitly specifying the Context.

A reference contains information on how to construct a copy of the object. The JNDI will attempt to turn references looked up from the directory into the Java objects that they represent so that JNDI clients have the illusion that what is stored in the directory are Java objects. In the JNDI, all naming and directory operations are performed relative to a context. There are no absolute roots. Once you have an initial context, you can use it to look up other contexts and objects.


Authentication Mechanisms

There are several ways in which a connection is created. The most common way is from the creation of an initial context. Each time an initial context is created, a new LDAP connection is created. See the Pooling section for information on how to change this behavior.

Hibernate is designed to operate in many different environments and, as such, there is a broad range of configuration parameters. Fortunately, most have sensible default values and Hibernate is distributed with an example hibernate. Simply put the example file in your classpath and customize it to suit your needs. An instance of org. Configuration represents an entire set of mappings of an application's Java types to an SQL database. The org.
