1.3 Types of Directory Server plug-ins
You can write the following types of plug-ins for Directory Server:
Preoperation/data validation The server calls a preoperation/data validation plug-in
function before performing an LDAP operation.
The main purpose of this type of plug-in is to validate data
before the data is added to the directory or before it is used
in an operation.
Postoperation/data notification The server calls a postoperation/data notification plug-in
function after performing an LDAP operation.
The main purpose of this type of plug-in is to invoke a
function after a particular operation is executed. For
example, you can write a plug-in that sends email to users
if their entries are modified.
Entry storage and entry fetch The server calls an entry storage plug-in function
immediately before writing data to the database back end.
