2.1 Where to Install the NT Domain Driver
The NT Domain driver provides synchronization for a single domain. Multiple domains require multiple Identity Manager driver installations. Consider initially setting up synchronization for a single domain and then using Identity Manager’s driver export and import functionality to expedite synchronization setup for additional domains. See the Novell Identity Manager 3.0.1 Administration Guide for information about driver export and import.The NT Domain driver can be installed in any of the following configurations:
2.1.1 Installation: Remote Loader on PDC
As shown in Installation Configuration: Remote Loader, install Novell® eDirectory™ and the Metadirectory engine on a Backup Domain Controller (BDC) or Member server. Then, install the NT Domain driver and the Remote Loader service on the Primary Domain Controller (PDC).
This configuration allows you to insulate the PDC, with the exception of the installation of two components that don’t require much disk space or many processing cycles.
It also allows the Identity Manager driver direct access to the PDC. From this position, the driver can manage any recovery scenarios independent of connection and API constraints.
Figure 2-1 Installation Configuration: Remote Loader
2.1.2 Installation: All Components on the PDC
As shown in Installation Configuration: All Components on the PDC, install Novell eDirectory, the Metadirectory engine, and the NT Domain driver on the PDC.
This configuration is optimal for processing speed because all components are installed on the same computer. Additionally, it allows the Identity Manager driver direct access to the PDC. From this position, the driver can manage any recovery scenarios independent of connection and API constraints.
However, the PDC is often restricted territory. Placing eDirectory on the PDC might be prohibited by your corporate policy.
To set up all components on the PDC, see Installing the NT Domain Driver (Local Install).

2.1.3 Installation: All Components on the BDC
As shown in Installation Configuration: All Components on the BDC, install Novell eDirectory, the Metadirectory engine, and the NT Domain driver on the BDC.
This configuration insulates the PDC completely.
However, because the driver must communicate with the PDC, this configuration can be problematic if the driver encounters any connection or other communication problems. For this reason, the previous configurations are recommended before this configuration.
To set up all components on the BDC, see Installing the NT Domain Driver (Local Install).
