Extending the Active Directory Schema for Bridge Networking

Preparing for the Cisco Unity Bridge Server Installation

---

In this chapter, you do the following tasks in the order listed:

1. Download the latest Windows 2000 Server service pack, and other required and recommended software. See the "Downloading Required and Recommended Software" section.

2. If you did not already modify the Active Directory schema to support Bridge Networking during the Cisco Unity 4.0(3) or later installation: Extend the Active Directory schema so that Cisco Unity can store information needed for Bridge Networking. See the "Extending the Active Directory Schema for Bridge Networking" section.

When you are finished with this chapter, return to "Overview of Mandatory Tasks for Installing the Cisco Unity Bridge" to continue installing the Bridge correctly.

---

Note The tasks in the overview list reference detailed instructions in the Cisco Unity Bridge Installation Guide and in other Bridge documentation. Follow the documentation for a successful installation.

Downloading Required and Recommended Software

For download instructions, refer to the "Downloading the Software for a Cisco Unity Bridge Installation or Upgrade" section of Release Notes for Cisco Unity Bridge Release 3.0<x> at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_release_notes_list.html.

The downloads are all self-extracting executable files. When all downloads are complete, extract the updates and burn CDs that contain the extracted files.

With the exception of Cisco Security Agent for Cisco Unity Bridge, required and recommended software is available on the Cisco Unity Bridge 3.0(x) CD. However, we recommend that you download the latest Microsoft service packs and updates, some of which may have been released or updated after the CD was produced.

---

Caution Until you have installed all of the recommended service packs and updates, and, optionally, Cisco Security Agent for Cisco Unity Bridge and virus-scanning software, third-party components installed on the Bridge server have significant security vulnerabilities. Do not connect the Bridge server to the network to install software. Instead, burn CDs that contain the downloaded software, and install the software from the CDs.

Extending the Active Directory Schema for Bridge Networking

Do the procedures in this section when the Active Directory schema has not been extended to support Bridge Networking in Cisco Unity 4.0(3) or later.

To support Bridge Networking, the Active Directory schema must be extended further than what was done for storing information specific to Cisco Unity. Note that even if the schema was modified to support Bridge Networking for an earlier version of Cisco Unity, it must be modified with the version of Omnigateway.ldf provided with Cisco Unity 4.0(3) or later. Do the procedure "To Extend the Active Directory Schema for Bridge Networking."

(To see the changes that the ADSchemaUpdate.exe program makes, browse to the directory Schema\LdifScripts on Cisco Unity DVD 1 or CD 1, and open the file Omnigateway.ldf in Notepad.)

If you are unsure whether the Active Directory schema has been extended for Bridge Networking, you can safely run ADSchemaUpdate.exe again (if the schema was extended, no additional changes will be made). Or you can do the procedure "To View the Active Directory Schema Version Description" to determine whether the extensions in the Cisco Unity 4.0(3) or later version of Omnigateway.ldf have been made.

To Extend the Active Directory Schema for Bridge Networking

---

Step 1 Confirm that all domain controllers are on line before making the schema updates. Schema replication will occur only when all domain controllers are on line.

Step 2 On the domain controller that is the schema master, log on by using an account that is a member of the Schema Administrators group.

Step 3 On Cisco Unity DVD 1 or CD 1, or from the location to which you saved the downloaded Cisco Unity CD 1 image files, browse to the directory ADSchemaSetup, and double-click ADSchemaSetup.exe.

Step 4 In the dialog box, double-click a row to choose the language in which you will view ADSchemaSetup.

Step 5 Check the Exchange 2000 Bridge Connector check box, and uncheck the other check boxes.

Step 6 Click OK.

Step 7 When the LDAP Data Interchange Format (LDIF) scripts have finished running, click OK.

Step 8 When the schema extension has finished, Ldif.log and LDif.err files are saved to the desktop. View the contents of the files to confirm that the extension completed successfully.

Step 9 Wait for the changes to the schema to replicate throughout the forest before adding information to the primary location and to delivery locations. Changes to the schema may take 15 minutes or more to replicate.

---

Note To determine whether changes have replicated and to force replication if necessary, use the Replication Monitor, which is available when you install Support Tools from the Windows 2000 compact disc.

A log file is generated each time the schema is updated. A shortcut to the directory where the log file is located is placed on the Windows desktop. In Cisco Unity 4.0(3) and later, the cisco-Ecsbu-UM-Schema-Version attribute was added to the LDIF script file Omnigateway.ldf. You can determine if the schema is at version 4.0(3) or later by searching the log file for the presence of the attribute.

To View the Active Directory Schema Version Description

---

Step 1 On the desktop of the server on which ADSchemaSetup.exe was run, open the directory Ldif logs, browse to the Omnigateway directory, and open the file Ldif.log in Notepad.

(Note that a separate directory and Ldif.log file are also saved for Avdirmonex2k.ldf and Vpimgateway.ldf; the directories are named after the LDIF script files provided with Cisco Unity 4.0(3) or later.)

Step 2 Scroll to the end of the file, and click the last line.

Step 3 On the Edit menu, click Find, enter cisco-Ecsbu-UM-Schema-Version, click Up for the direction of the search, and click Find Next.

If the attribute is not found, then the schema has not been updated for Bridge Networking in Cisco Unity 4.0(3) or later. Do the procedure "To Extend the Active Directory Schema for Bridge Networking."

If the attribute is found, a few lines down you should see a line containing the word "Description" followed by "Unity Bridge 4.0(3)."
