The GenericNull Services driver provides a minimal driver that allows a driver shim to be set up to perform tasks that are completely implemented in policy. It is similar to the GenericLoopBack driver in the function it serves. It is different in one important way: it does not connect the Subscriber channel to the Publisher channel, but rather acts as a sink for most operations, simulates doing something with operations, but returning success. The only information sent on the Publisher channel to the Identity Manager engine is the driver heartbeat.
The GenericNull Services driver is automatically installed when you install the Metadirectory Server option using the Identity Manager installation program. The driver runs on the platforms supported by Identity Manager and the Remote Loader service. The driver does not require a separate activation. When you activate the Metadirectory engine, the driver is also activated.
A base configuration of the driver does not contain much information:
An empty filter.
Publisher heartbeat configuration option is available, but it is set to Disabled.
No prompts for information when importing the driver.
Typical usage of the GenericNull Services Driver includes the following:
Adding the classes and attributes that you want to monitor for change in the Subscriber Filter asfor the class and for the attribute.
Add Subscriber Event Transformation policies that react to specific object or attribute changes and perform actions such as:
Modifications back into the Identity Vault (using actions that manipulate source attributes and objects).
Generate custom Audit Events.
Call extension functions to communicate the change outside of Identity Manager.
Add a final Subscriber Event Transformation policy that vetoes all events.
To configure the GenericNull Services driver :
In iManager, select.
Select a driver set, then click.
If you place this driver in a new driver set, you must specify a driver set name, context, and associated server.
Select how you want the driver configurations sorted:
Identity Manager 3.5 configurations
Identity Manager 3.0 configurations
Configurations not associated with an IDM version
Select, then click .
Specify a name for the driver, then click.
Define security equivalences for the driver and exclude administrative roles from replication, then click.
