LDIF Component

Since Camel 2.20

Only producer is supported

The LDIF component allows you to do updates on an LDAP server from a LDIF body content.

This component uses a basic URL syntax to access the server. It uses the Apache DS LDAP library to process the LDIF. After processing the LDIF, the response body will be a list of statuses for success/failure of each entry.

The Apache LDAP API is very sensitive to LDIF syntax errors. If in doubt, refer to the unit tests to see an example of each change type.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ldif</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

ldif:ldapServerBean[?options]

The ldapServerBean portion of the URI refers to a LdapConnection. This should be constructed from a factory at the point of use to avoid connection timeouts. The LDIF component only supports producer endpoints, which means that an ldif URI cannot appear in the from at the start of a route.

For SSL configuration, refer to the camel-ldap component where there is an example of setting up a custom SocketFactory instance.

You can append query options to the URI in the following format, ?option=value&option=value&…​

Options

The LDIF component supports 3 options, which are listed below.

Name Description Default Type

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

The LDIF endpoint is configured using URI syntax:

ldif:ldapConnectionName

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

ldapConnectionName

Required The name of the LdapConnection bean to pull from the registry. Note that this must be of scope prototype to avoid it being shared among threads or using a connection that has timed out.

String

Query Parameters (3 parameters):

Name Description Default Type

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ldif-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 4 options, which are listed below.

Name Description Default Type

camel.component.ldif.basic-property-binding

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

Boolean

camel.component.ldif.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.ldif.enabled

Whether to enable auto configuration of the ldif component. This is enabled by default.

Boolean

camel.component.ldif.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

Body types:

The body can be a URL to an LDIF file or an inline LDIF file. To signify the difference in body types, an inline LDIF must start with:

version: 1

If not, the component will try to parse the body as a URL.

Result

The result is returned in the Out body as a ArrayList<java.lang.String> object. This contains either "success" or an Exception message for each LDIF entry.

LdapConnection

The URI, ldif:ldapConnectionName, references a bean with the ID, ldapConnectionName. The ldapConnection can be configured using a LdapConnectionConfig bean. Note that the scope must have a scope of prototype to avoid the connection being shared or picking up a stale connection.

The LdapConnection bean may be defined as follows in Spring XML:

<bean id="ldapConnectionOptions" class="org.apache.directory.ldap.client.api.LdapConnectionConfig">
  <property name="ldapHost" value="${ldap.host}"/>
  <property name="ldapPort" value="${ldap.port}"/>
  <property name="name" value="${ldap.username}"/>
  <property name="credentials" value="${ldap.password}"/>
  <property name="useSsl" value="false"/>
  <property name="useTls" value="false"/>
</bean>

<bean id="ldapConnectionFactory" class="org.apache.directory.ldap.client.api.DefaultLdapConnectionFactory">
  <constructor-arg index="0" ref="ldapConnectionOptions"/>
</bean>

<bean id="ldapConnection" factory-bean="ldapConnectionFactory" factory-method="newLdapConnection" scope="prototype"/>

or in a OSGi blueprint.xml:

<bean id="ldapConnectionOptions" class="org.apache.directory.ldap.client.api.LdapConnectionConfig">
  <property name="ldapHost" value="${ldap.host}"/>
  <property name="ldapPort" value="${ldap.port}"/>
  <property name="name" value="${ldap.username}"/>
  <property name="credentials" value="${ldap.password}"/>
  <property name="useSsl" value="false"/>
  <property name="useTls" value="false"/>
</bean>

<bean id="ldapConnectionFactory" class="org.apache.directory.ldap.client.api.DefaultLdapConnectionFactory">
  <argument ref="ldapConnectionOptions"/>
</bean>

<bean id="ldapConnection" factory-ref="ldapConnectionFactory" factory-method="newLdapConnection" scope="prototype"/>

Samples

Following on from the Spring configuration above, the code sample below sends an LDAP request to filter search a group for a member. The Common Name is then extracted from the response.

ProducerTemplate<Exchange> template = exchange.getContext().createProducerTemplate();

List<?> results = (Collection<?>) template.sendBody("ldif:ldapConnection, "LDiff goes here");

if (results.size() > 0) {
  // Check for no errors

  for (String result : results) {
    if ("success".equalTo(result)) {
      // LDIF entry success
    } else {
      // LDIF entry failure
    }
  }
}
