LDAP Authenticator

This is a simple dropwizard-auth module using Basic-Auth + LDAP for authentication.

Maven

<dependency>
    <groupId>com.yammer.dropwizard</groupId>
    <artifactId>dropwizard-auth-ldap</artifactId>
    <version>2.1.3-1</version>
</dependency>

Initialize the bundle

I assume you are already familiar with dropwizard's authentication module. You can find more information about dropwizard authentication at http://www.dropwizard.io/manual/auth.html

Here is an example how to use LdapAuthenticatorBundle:

@Override
public void bootstrap(final Bootstrap<ServiceConfiguration> bootstrap)throws Exception{
        LdapAuthenticatorBundle ldapBundle=new LdapAuthenticatorBundle<ServiceConfiguration>(){

public LdapConfiguration getCOnfiguration(ServiceConfiguration configuration){
        configuration.getLdapConfiguration()
        }
        }
        }

Define resource with Ldap authentication annotations

@Path("/")
@Produces(MediaType.APPLICATION_JSON)
@Slf4j
@Singleton
@Api(value = "Login")
@AllArgsConstructor
@NoArgsConstructor
public class LoginResource {

    @POST
    @Path("/login")
    @RolesAllowed({"USER"})
    public Response login(@Auth User user) {
        return Response.ok().build();
    }
}

Register the resource

environment.jersey().register(new LoginResource());
