Error Message Discovering "Microsoft DMD" and "Configuration" Object (255685)


The information in this article applies to:

  • Microsoft Metadirectory Services 2.1
This article was previously published under Q255685

SYMPTOMS

In Microsoft Metadirectory Services (MMS) version 2.1 (build 261), the following error message is reported by the Exchange LDAP Management Agent (MA) when you are discovering the "Microsoft DMD" and "Configuration" schema containers :
Unknown LDAP search error - Microsoft DMD

Unknown LDAP search error - Configuration

CAUSE

This behavior occurs when you are performing a full discovery on a Microsoft Exchange site, beginning at the root. MMS 2.1 does not require that the schema be explicitly discovered. In addition, it appears as though these two low-level containers on the Exchange site are also invisible to the Exchange Administration tool.

RESOLUTION

In the MA configuration, hard-code the container names that should be excluded during the discovery process. Do this by modifying the contents of zcLdapExcludedHierarchy:
  1. Click the Exchange LDAP Management Agent.
  2. In the Actions panel, click Configure MA.
  3. Click the Connected Directory Specifics tab.
  4. Click the Advanced tab.
  5. Click in the DNs to Exclude during the Discovery box.
  6. Type the distinguished names of the "Microsoft DMD" and "Configuration" objects as they appear in the Exchange site.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
