In the X.500 model, an object entry has a single structural
object class which is determined by examining the inheritance
of structural object classes list in the entry's structural
objectclass attribute to find the class which is deepest in
the super class chain. That is, if 'person', 'organizationalPerson',
and 'inetOrgPerson' are provided by the user as objectClass
values, the object is structurally an inetOrgPerson object.
Some servers, including OpenLDAP 2.0, do not enforce structural
object class restrictions. However, this should not be taken
as a license to abuse the restriction. Eventually you run
into a server (such as a future version of OpenLDAP) which does
enforce these restrictions.
