A Driver object in Micro Focus Identity Manager is a fundamental container object within an eDirectory (or other LDAP directory) tree. Its primary role is to manage the connection and data synchronization logic between the Identity Vault and a connected application. To achieve this, the Driver object directly contains two key types of child objects:

1. Subscriber and Publisher objects: These represent the two channels of data flow. The Publisher channel processes events from the connected application to the Identity Vault, while the Subscriber channel processes events from the Identity Vault to the connected application.

2. Policy Objects: These objects define the rules, transformations, and logic for how data is handled. Policies are attached to the driver and its channels to control everything from schema mapping to event transformation.

A. Packages: Packages are deployment and management units used to install or upgrade drivers and their configurations, not objects contained within a Driver object itself.

B. Driver Set: A Driver Set is the parent container for one or more Driver objects; a driver is contained within a Driver Set, not the other way around.

D. Application driver shim: The shim is the executable component (e.g., a .jar or .dll file) that communicates with the application. The Driver object configures and references the shim, but the shim file is not an eDirectory object contained within it.

1. Micro Focus Identity Manager 4.8 Administration Guide: In Chapter 3, "Understanding the Identity Manager Engine and Drivers," the section "The Driver Object" states, "A Driver object is a container for the Publisher and Subscriber channels. Each channel has its own set of policies that control the flow and transformation of data." This directly supports that a Driver object contains Subscriber/Publisher objects and Policy objects.

2. Micro Focus Identity Manager 4.8 Policies in Identity Manager Guide: Chapter 1, "Introduction to Policies," describes how policies are created as objects in eDirectory and then linked to specific points in the Identity Manager data flow, such as a driver's Publisher channel, Subscriber channel, or specific policies like an Input Transformation policy set. This confirms that Policy objects are integral components associated with a Driver object.

3. NetIQ Identity Manager 4.5 Understanding Identity Manager: In the section "The Components of Identity Manager," Figure 2-1, "Identity Manager Components in eDirectory," visually depicts the eDirectory tree structure. It clearly shows a Driver object containing both a Publisher object and a Subscriber object as its children, along with various DirXML-Policy objects. This provides a structural confirmation of the correct answer.
