The IDirectoryObject::SetObjectAttributes method modifies data in one or more specified object attributes defined in the ADS_ATTR_INFO structure.

HRESULT SetObjectAttributes( 
  PADS_ATTR_INFO pAttributeEntries,
  DWORD dwNumberAttributes,
  DWORD* pdwNumAttributesModified


[in] Provides an array of attributes to be modified. Each attribute contains the name of the attribute, the operation to perform, and the attribute value, if applicable. For more information, see the ADS_ATTR_INFO structure.
[in] Provides the number of attributes to be modified. This value should correspond to the size of the pAttributeEntries array.
[out] Provides a pointer to a DWORD variable that contains the number of attributes modified by the SetObjectAttributes method.

Return Values

This method returns the standard return values, including S_OK when the attributes are set successfully.

For more information and other return values, see ADSI Error Codes.


In Active Directory (LDAP provider), the IDirectoryObject::SetObjectAttributes method is a transacted call. The attributes are either all committed or discarded. Other directory providers may not transact the call.

Active Directory does not allow duplicate values on a multi-valued attribute. However, if you call SetObjectAttributes to append a duplicate value to a multi-valued attribute of an Active Directory object, the SetObjectAttributes call succeeds but the duplicate value is ignored.

Similarly, if you use SetObjectAttributes to delete one or more values from a multi-valued property of an Active Directory object, the operation succeeds even if any or all of the specified values are not set for the property

Example Code [C++]

The following C++ code example sets the sn attribute of a user object to the value of Price as a case-insensitive string.

IDirectoryObject *pDirObject=NULL;
DWORD  dwReturn;
ADSVALUE  snValue;
DWORD dwAttrs = sizeof(attrInfo)/sizeof(ADS_ATTR_INFO); 
snValue.CaseIgnoreString = L"Price";
hr = ADsGetObject(L"LDAP://CN=Jeff Smith,OU=Sales,DC=Fabrikam,DC=com",
		(void**) &pDirObject );
if ( SUCCEEDED(hr) )
	hr = pDirObject->SetObjectAttributes(attrInfo, dwAttrs, &dwReturn);
