    Description

      I am using the apacheDS API (org.apache.directory.api:api-all:1.0.0) to forward the DSML messages I received in my app to my local LDAP directory (apacheDS).

      When I forward such a message :

       
      <
      batchRequest xmlns="urn:oasis:names:tc:DSML:2:0:core">
        <authRequest principal="a8717135-81e3-4fc2-bcbe-5180d8a274fb@1.1.1.2.2" requestID="4948"/>
      ...
      </batchRequest>
       
      The Dsmlv2Engine.process(OutputStream, OutputStream) method logs
       
      2020-09-07 14:08:41,201 WARN () [org.apache.directory.api.dsmlv2.engine.Dsmlv2Engine] (http-/0.0.0.0:8080-1 ) Failed to process request: java.lang.NullPointerException

      and the received response is :
      <batchResponse xmlns="urn:oasis:names:tc:DSML:2:0:core" requestID="0">
      <errorResponse requestID="2" type="gatewayInternalError">
      <message>ERR_03003 Internal Error: null</message>
      </errorResponse>
      </batchResponse>
       
      This seems to happen because the writeResponse method in class Dsmlv2Engine uses

       respDsml.toDsml( null );

      which throw NullPointerException when trying to do
      Element element = root.addElement( "authResponse" );

      which seems to be inevitable as we input null.

       
      This happens in version 1.0.0 but also with the 2.0.1 after update of the dependency.
      Thanks in advance for your insights.
