result counter problem from ldapsearch

[Kurt Zeilenga <kurt@OpenLDAP.org>]

Dear all,
 
I installed OpenLDAP version 2.2.23 on RedHat 7.3 and created a tree.
Nevertheless, I always obtain "result: 0 Success" from ldapsearch result
but actually it return an entry to me. Is there any setting or problem
with OpenLDAP I need to set in order to make the search result counter
works? Thx.
 
Below is the output of the ldapsearch.
 
Cheers,
CK
