I have used the component LDAPReader.  
I have given the LDAPUrl also mentioning the host and port number.  
I have also given the BaseDN and filter field.  
When I run the graph, I get an error message  
Exception in thread “main” java.lang.RuntimeException: Can’t create object of type LDAP\_READER with reason: null

Please can somebody provide a solution for this?

Hello, _scope_ attribute is missing. I’ve reported in our bug tracking system ([http://bug.cloveretl.com/view.php?id=3158](http://bug.cloveretl.com/view.php?id=3158)), that Clover can’t find the default value of this attribute.
