I can't connect to LDAP With LDAP Connector

If some could help I will thank it.

I have created an input connector to LDAP to an automatic task, when I test de Connector I Get the next error:

java.lang.reflect.InvocationTargetException
org.bonitasoft.engine.exception.BonitaRuntimeException: USERNAME=install | java.lang.NullPointerException

And when I execute a new instance of the flow, I don’t get any response, neither in the Bonita Log file.

I think I have problems with the data that I get from the LDAP, I am converting it in a bad way.

Thank’s

I got this in the Log when push the button of test:
