SYMPTOMS
When you make a Lightweight Directory Access Protocol (LDAP) connection by using an LDAP client that is not supplied with Microsoft Metadirectory Services (MMS), the MMS logon credentials may not be correctly verified.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes. Apply it only to systems that you determine are at risk of attack. Evaluate the computer's physical accessibility, network and Internet connectivity, and other factors to determine the degree of risk to the computer. See the associated Microsoft Security Bulletin to help determine the degree of risk. This hotfix may receive additional testing. If the computer is sufficiently at risk, we recommend that you apply this hotfix now.

To resolve this problem immediately, download the hotfix by following the instructions later in this article or contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:

Note In special cases, charges that are ordinarily incurred for support calls may be canceled, if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

Installation Information
Before you apply the update, stop the MMS Server service. If a ZoomServ folder exists on drive C, the update is applied to that folder. This occurs even if the C:\ZoomServ folder is empty. If you installed MMS in a different folder, delete the empty C:\ZoomServ folder, and then reapply this update. The patch installation will then prompt you for the location of MMS.

This update does not support any installation switches. After you apply the update, restart the MMS Server service.
