Constructed attributes
A constructed attribute is an attribute whose value is computed from values that are assigned to other attributes. For example, the system might construct a full- or common-name attribute, cn, from values that are assigned to the standard givenName and sn attributes, as follows:
dsconfig create-constructed-attribute
--attribute-name ReqConstructedCN --set attribute-type:cn \
--set 'value-pattern:{givenName} {sn}'
Beginning with Delegated Admin 3.5.0 and PingDirectory server 7.3.0.1, the value of a constructed attribute can be updated automatically whenever the value of a source attribute is created or when it is edited.
dsconfig set-rest-resource-type-prop \ --type-name users \ --set post-create-constructed-attribute:ReqConstructedCN \ --set update-constructed-attribute:ReqConstructedCN
In these examples, a change to the value of givenName or sn forces a corresponding change to the value of cn. Attributes that contribute to a required constructed attribute are identified in the UI as Required even if they were not originally designated as such. Because cn is a required attribute in this example, givenName and sn are also required.

An attribute’s capability of being changed after its creation is called its mutability. |
As with standard attributes, constructed attributes are stored as Lightweight Directory Access Protocol (LDAP) attributes in a database like the PingDirectory server.
