it can be said that an object class inherits the sets of *allowed* and required attributes from its superclasses
Therefore the top object class contains all possible attributes? OR
A subclasses cannot contain any attribute which is not included in it's superclass?
A subclass contains definitions for all the MAY attributes that the superclass contains as MAY attributes, and all the MUST attributest that the superclass contains as MUST attributes.
therefore, an entry including our inheriting subclass: MUST contain all the MUST attributes included in the superclass(es) MUST contain all the MUST attributes included in our subclass MAY contain all the MAY attributes included in the superclass(es) MAY contain all the MAY attributes included in our subclass
as an example:
given this objectClasses 'tree': objectClasses: ( 0.0.0.0 NAME 'myparent' MUST cn MAY uid ) objectClasses: ( 0.0.0.1 NAME 'mysub' SUP myparent MUST mail MAY mobile )
an entry containing the sub objectClass mysub MUST contain: cn (inherited from myparent), mail MAY contain: uid (inherited from myparent), mobile
hope this helps
