Description
Declares an entry fetch plug-in, which is called by the server after retrieving an
entry from the default back-end database.
Example of use: If you encrypt data with an entry store plug-in function before
saving the data to the database, you can define an entry fetch function that
decrypts data after reading it from the database.
Declares an entry store plug-in, which is called by the server before saving an
entry to the default back-end database. (If you are writing your own database
plug-in, you do not need to use this plug-in.)
Example of use: You can define an entry store function to encrypt data before
saving the data to the database.
Declares an extended operation plug-in, which is called by the server when
receiving a request for an extended operation from a client.
Declares a matching rule plug-in, which is called by the server when receives a
search request with an extensible matching search filter from a client.
This type of plug-in is also called by the server when indexing attributes for the
back-end database.
Declares a post-operation/data notification plug-in, which is called by the
server after performing an LDAP operation.
Example of use: You can define a data notification function to send notification
to the administrator if certain data has changed.
