Disabling the Double Delta Functionality in MMS 2.2 SP1 (304327)


The information in this article applies to:

  • Microsoft Metadirectory Services 2.2 SP1
This article was previously published under Q304327

SYMPTOMS

After you upgrade to Microsoft Metadirectory Services (MMS) 2.2 Service Pack 1 (SP1), you may notice that the Active Directory management agent (ADMA) takes more time to process and makes multiple passes on the data when it is processing deltas.

CAUSE

This behavior is caused by new functionality that was introduced in MMS 2.2 SP1 to help resolve issues that involve list membership and distinguished name-based (DN-based) attributes that are not updated in Active Directory when running in delta mode. If the ADMA configuration does not require DN-based attributes (such as the Manager attribute), or if group membership processing is not required, there is no way to disable this new functionality. If bulk user exports to Active Directory are required, the new double delta functionality may cause too large a performance degradation. By using the hotfix that is described in this article, administrators can disable the double delta functionality that was introduced in MMS 2.2 SP1.
