Chapter 321. Spring LDAP Component
Available as of Camel version 2.11
The spring-ldap: component provides a Camel wrapper for Spring LDAP.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring-ldap</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>321.1. URI format
spring-ldap:springLdapTemplate[?options]
Where springLdapTemplate is the name of the Spring LDAP Template bean. In this bean, you configure the URL and the credentials for your LDAP access.
321.2. Options
The Spring LDAP component has no options.
The Spring LDAP endpoint is configured using URI syntax:
spring-ldap:templateName
with the following path and query parameters:
321.2.1. Path Parameters (1 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| templateName | Required Name of the Spring LDAP Template bean | String |
321.2.2. Query Parameters (3 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
| operation (producer) | Required The LDAP operation to be performed. | LdapOperation | |
| scope (producer) | The scope of the search operation. | subtree | String |
| synchronous (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean |
321.3. Spring Boot Auto-Configuration
The component supports 2 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
| camel.component.spring-ldap.enabled | Enable spring-ldap component | true | Boolean |
| camel.component.spring-ldap.resolve-property-placeholders | Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. | true | Boolean |
321.4. Usage
The component supports producer endpoint only. An attempt to create a consumer endpoint will result in an UnsupportedOperationException.
The body of the message must be a map (an instance of java.util.Map). Unless a base DN is specified by in the configuration of your ContextSource, this map must contain at least an entry with the key dn (not needed for function_driven operation) that specifies the root node for the LDAP operation to be performed. Other entries of the map are operation-specific (see below).
The body of the message remains unchanged for the bind and unbind operations. For the search and function_driven operations, the body is set to the result of the search, see http://static.springsource.org/spring-ldap/site/apidocs/org/springframework/ldap/core/LdapTemplate.html#search%28java.lang.String,%20java.lang.String,%20int,%20org.springframework.ldap.core.AttributesMapper%29.
321.4.1. Search
The message body must have an entry with the key filter. The value must be a String representing a valid LDAP filter, see http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol#Search_and_Compare.
321.4.2. Bind
The message body must have an entry with the key attributes. The value must be an instance of javax.naming.directory.Attributes This entry specifies the LDAP node to be created.
321.4.3. Unbind
No further entries necessary, the node with the specified dn is deleted.
321.4.4. Authenticate
The message body must have entries with the keys filter and password. The values must be an instance of String representing a valid LDAP filter and a user password, respectively.
321.4.5. Modify Attributes
The message body must have an entry with the key modificationItems. The value must be an instance of any array of type javax.naming.directory.ModificationItem
321.4.6. Function-Driven
The message body must have entries with the keys function and request. The function value must be of type java.util.function.BiFunction<L, Q, S>. The L type parameter must be of type org.springframework.ldap.core.LdapOperations. The request value must be the same type as the Q type parameter in the function and it must encapsulate the parameters expected by the LdapTemplate method being invoked within the function. The S type parameter represents the response type as returned by the LdapTemplate method being invoked. This operation allows dynamic invocation of LdapTemplate methods that are not covered by the operations mentioned above.
Key definitions
In order to avoid spelling errors, the following constants are defined in org.apache.camel.springldap.SpringLdapProducer:
- public static final String DN = "dn"
- public static final String FILTER = "filter"
- public static final String ATTRIBUTES = "attributes"
- public static final String PASSWORD = "password";
- public static final String MODIFICATION_ITEMS = "modificationItems";
- public static final String FUNCTION = "function";
