-This namespace element causes the base packages to be scanned for interfaces that extend `LdapRepository` and create Spring beans for each one found. By default the repositories get an autowired `LdapTemplate` Spring bean that is called `ldapTemplate`, so you only need to configure `ldap-template-ref` explicitly if you deviate from this convention.

-If you want to go with Java configuration, use the `@EnableLdapRepositories` annotation. The annotation carries the same attributes as the namespace element. If no base package is configured, the infrastructure scans the package of the annotated configuration class. The following example shows how to set up Java configuration:

 Because our domain repository extends `CrudRepository`, it provides you with CRUD operations as well as methods for access to the entities. Working with the repository instance is a matter of dependency injecting it into a client.
