Individual Constructed Attribute, other than rootDSE Attributes, are specified in [MS-ADA1], [MS-ADA2], and [MS-ADA3].
But briefly, Constructed Attribute have the property that they are attributes for which the attribute value is computed by using other attributes, sometimes from other objects.
Regardless of this property, Constructed Attribute are defined to be those attributes that meet one of the following three criteria:
- The attributeSchema object's systemFlags attribute has the ATTR_IS_CONSTRUCTED bit (section 2.2.10) set to one.
- The attribute is a rootDSE attribute (see section 22.214.171.124.2).
- The attribute is a back link attribute.
Except as otherwise noted, these constructed attributes are applicable to both AD DS and AD LDS.
