My nitpick regarding this feature is that it still exists. :-)

Actually there still are complaints that OpenLDAP has lost cldap - from people trying to get Windows/Samba to cooperate with OpenLDAP. Windows apparently sends a cldap message as an "LDAP ping". http://ubuntuforums.org/showthread.php?t=673292 http://onemansjourneyintolinux.blogspot.com/2008/06/cldap.html

Personally I only compiled it since it exists - I randomize my config options a bit now and then for testing.
