LDAP callback error

Hello,

I have set up the LDAP and in ldap_login.conf I set up syncCallbackClass="com.test.ldap.LDAPConnector". I then created the bundle that contains the class LDAPConnector that extends the Callback. 

However, after deploying the bundle I am seeing following error. Looks like it is not finding the class in the bundle.

27.02.2014 17:16:34.633 *ERROR* [127.0.0.1 [1393521394629] PUT /libs/sling/topology/connector.521e314c-30be-4efc-b9df-24f03f3d6af6.json HTTP/1.1] com.day.crx.security.ldap.LDAPUserSync Unable to initialize synchronization callback java.lang.ClassNotFoundException: com.test.ldap.LDAPConnector not found by com.day.crx.sling.server [65]

Any pointer would be greatly appreciated.

LDAP Callbacks are not DS components, so you can't use @Reference.

If you need access to the JCR Session from an LDAP Callback, you need to implement the interface com.day.crx.security.ldap.sync.ExtendedCallback. It unfortunately does not appear that this interface is listed in the public JavaDoc.

Justin - thank you for the prompt response.

I do not see ExtendedCallback class in "com.day.crx.security.ldap.sync" package. Is it available publicly?

Here is my dependency:    

            <dependency>
                <groupId>com.day.crx</groupId>
                <artifactId>crx-auth-ldap</artifactId>
                <version>2.3.5</version>
                <scope>provided</scope>
            </dependency>

I get java.lang.NullPointerException

@Reference
private SlingRepository repository;
private Session session;

.....

try {
          LOGGER.debug("trying to get session..");
          repository.login();
          session = repository.loginAdministrative(null);
          LOGGER.debug("session " + session);

       } finally {   
                         session.logout(); 
                   }

 

Thanks

I have a follow up question.

Looks like I do not have access to the session from the LDAP callback. How do I get the user stored in crx to update its property in callback method? Do I need to connect to Repo programmatically?

Ah found the issue. I had to refresh "Day CRX LDAP Authenticationcom.day.crx.crx-auth-ldap" bundle.

In your bundle have you exported package?
