OID value: 1.3.6.1.4.1.10471.3
OID description:
This field contains an arbitarary string, intended to
ensure that the object's DN field is unique.
Sometimes the same CN attribute value must be used in
multiple objects, because a single owner requests multiple
objects. If this can occur, a distinguishing minor number
is added to the DN of the object.
