Active Directory operations fail with 'More data is available'

Description

Attempting to run an Active Directory operation fails. Examining the logs shows DirectoryServicesCOMException.

Affected Software

  • FIM Event Broker

Symptom

A DirectoryServicesCOMException such as the following appears in the Event Broker logs:

System.DirectoryServices.DirectoryServicesCOMException (0x800700EA): More data is available.
at System.DirectoryServices.SearchResultCollection.ResultsEnumerator.MoveNext()
at System.DirectoryServices.SearchResultCollection.get_InnerList()
at System.DirectoryServices.SearchResultCollection.get_Count()
at Unify.Product.EventBroker.ADSyncChangesPlugIn.GetChanges(DirectorySearcher searcher)
at Unify.Product.EventBroker.ADChangesPlugInBase.Check()
at Unify.Product.EventBroker.OperationListExecutorBase.RunCheck(ICheckOperationFactoryInformation checkOperation)

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>
TIP: This fixes a known issue with directory services paging.
