Apache Directory Service LDAP

http://directory.apache.org/

install "Apache DS" and "Apache Directory Studio"

DS logs are in D:\apps\ApacheDS\instances\default\log

Open Studio, LDAP / new Connection, port 10389, host localhost, username uid=admin,ou=system password secret
(see http://directory.apache.org/apacheds/basic-ug/1.4.2-changing-admin-password.html )

if you see this in apacheds logs, no worries:
"[org.apache.directory.server.core.DefaultDirectoryService] - You didn't change the admin password of directory service instance 'default'. Please update the admin password as soon as possible to prevent a possible security breach."

DS conf is in D:\apps\ApacheDS\conf\wrapper.conf

To find out at which port the ActiveDS is actually listening (NOT on the default 389 port, but on 10389) I recommend using TCPVIEW.
