Moving the Root Tenant OU for the Lync Server 2010 Multitenant Pack for Partner Hosting

This article provides guidance for telcos and hosting or service providers that currently have hosted or on-premises Exchange deployed with an organizational unit (OU) for tenants. The OU structure in the Lync Server 2010 Multitenant Pack for Partner Hosting is predetermined, and cannot be changed. If you need to install it into your environment and use your existing OU for tenants as the root OU for the Lync Server Multitenant Hosting Pack, you can use the following procedure.

You can change the root organizational unit (OU) when installing the Lync Server 2010 Multitenant Hosting Pack in an Active Directory environment that already has an organizational unit for tenants, or when you want to change the root tenant OU for any reason. This procedure describes how to use ldp.exe to change the otherWellKnownObjects attribute to point to the root tenant OU.

Caution: The information in this section is included in response to customer requests. The steps in this procedure are untested and are, therefore, not supported by Microsoft. The information is provided, without support or warranty, to enable hosting partners to change the root OU folder only if it is absolutely necessary within their deployment.

To change the root OU for a tenant

1. Run ldp.exe.

2. In the Connection menu, click Connect.

3. In the Connection menu, click Bind.

4. In the View menu, click Tree and select the configuration partition from drop-down menu, then click OK.

Note: The configuration partition option is the one that begins with “CN=Configuration”.

5. Right-click the root node, select Modify, and then do the following:

a. In the Edit Entry box, enter “otherWellKnownObjects” for Attribute and “B:32:DE8197E3283B2C439A62F871E529F7DD:<DN of root tenant OU here>” for Values.

b. In the Operation box, select Replace and then click Enter.

c. Click Run.

6. On the Connection menu, click Exit to close ldp.exe.


After completing this procedure, the root OU for tenants is changed to the OU specified in Step 5.
