Unable to load data from a LDAPServer to CloverETL

Hi,

I have used the LDAPReader as per the example graphLdapReader_Uninett.grf given from CloverETL.
Following is the node code of the graph.
The graph is executed successfully without any errors.But the metadata that gets propagated in the graph is null.
How can I be sure whether clover is connected to my LDAPServer?
.Please can anyone suggest a solution for this as I am in need of this solution critically for my project
:cry:
Following is the node code
