Java library for simpler LDAP programming

 Spring LDAP is built on the same principles as the JdbcTemplate in Spring
 JDBC. It completely eliminates the need to worry about creating and closing
 LdapContext and looping through NamingEnumeration. It also provides a
 more comprehensive unchecked Exception hierarchy, built on Spring's
 DataAccessException. As a bonus, it also contains classes for dynamically
 building LDAP filters and DNs (Distinguished Names), LDAP attribute
 management, and client-side LDAP transaction management.
