Spring LDAP is a library to simplify LDAP programming in Java, built on the same principles as Spring Jdbc.
The LdapTemplate class encapsulates all the plumbing work involved in traditional LDAP programming, such as creating, looping through NamingEnumerations, handling Exceptions and cleaning up resources. This leaves the programmer to handle the important stuff - where to find data (DNs and Filters) and what to do with it (map to and from domain objects, bind, modify, unbind, etc.), in the same way that JdbcTemplate relieves the programmer of all but the actual SQL and how the data maps to the domain model.
In addition to this, Spring LDAP provides Exception translation from NamingExceptions to an unchecked exception hierarchy, as well as several utilities for working with filters, LDAP paths and attributes.
