Introduction

This guide serves as an introduction to architectural concepts related to and administration of Triggers in ApacheDS. ApacheDS is the first server to provide Triggers for LDAP like their counterparts in RDBMS world. The Trigger Model in ApacheDS has been carefully designed to be LDAP standards compliant and to take advantage of powerful aspects of ApacheDS like The Administrative Model. A Trigger basically provides a mechanism to register some sort of action to be fired upon an event. To restate this considering ApacheDS Triggers, Triggers allow you to register Stored Procedure invocations to be fired upon any change-inducing LDAP operations on some set of selected entries. Triggers also provides some facilities to make them even more usable like allowing to pass request parameters to stored procedures. To make the most sense of this powerful construct you need to first understand The Administrative Model and have a look at Stored Procedures.
