Mapping Active Directory Instances

  • Article

In general, each Active Directory object maps to exactly one WMI instance. The WMI class corresponding to the WMI instance is the same as the class provided by the class provider from the corresponding Active Directory class. The key property ADSIPath of each instance is filled in with the ADSI path of the object.

The following sections are discussed in this topic:

Mapping Namespaces

Each of the namespaces in ADSI map one-to-one to namespaces in the WMI \root\directory namespace. The name of the WMI namespace is the same as the ProgId value of the Directory Services provider that provides the namespace. Specifically, Active Directory maps to the \LDAP namespace in the \root\directory namespace. WMI creates the \LDAP namespace as a part of the class provider registration process.

Mapping Attribute Values

The following table lists the mapping between each attribute of an Active Directory object and a WMI property.

Active Directory syntax WMI data type WMI property value
Access-Point CIM_STRING Mapped from the value of the string.
Boolean CIM_BOOLEAN Mapped directly to the appropriate Boolean value.
Case Insensitive String CIM_STRING Mapped from the value of the string.
Case Sensitive String CIM_STRING Mapped from the value of the string.
Distinguished Name CIM_STRING Mapped from the value of the string.
DN-Binary Embedded object of class DN_With_Binary Mapped to instances of the DN_With_String class.
DN-String Embedded object of class DN_With_String Mapped to instances of the DN_With_String class.
Enumeration CIM_SINT32 Mapped directly to the integer value.
IA5-String CIM_STRING Mapped from the value of the string.
Integer CIM_SINT32 Mapped directly to the integer value.
NT Security Descriptor Embedded object of Class Uint8Array Mapped to instances of the Uint8Array class.

Mapping Instance Associations

The Directory Services provider maps the different container relationships in Active Directory using instances of the DS_LDAP_Instance_Containment class.
