Resolution

Locate the *.exe.config in the Event Broker services directory, for an x64 installation this will be (by default):

C:\Program Files\UNIFY Solutions\Event Broker\Services\Unify.Service.Event.exe.config

and for an x86 installation this will be (by default):

C:\Program Files\UNIFY Solutions\Event Broker\Services\Unify.Service.Event32.exe.config

Add the following to the *.exe.config of the Event Broker services directory, inside the <configuration> element:

<configSections>
    <section name="system.directoryservices" type="System.DirectoryServices.SearchWaitHandler, System.DirectoryServices, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
  </configSections>
  <system.directoryservices>
    <DirectorySearcher waitForPagedSearchData="true" />
  </system.directoryservices>
