samba - Dec 2013 - LDAP server listening on UDP for resource location

Hi,

  If I understand the MS documentation right a Windows desktop uses DNS (or 
WINS) to determine a DC and then connects to the ldap udp port 389 to get 
further details about the DC.  I do not want to run a full DC but only a 
"simple" Heimdal or MIT kdc for Browser Negotiate authentication. 
Does
Samba include such a standalone ldap service which just returns the only 
supported service is the KDC ?

This is what an AD server would return.
