"An object or alias entry is characterized by precisely one structural object class superclass chain which has a single structural object class as the most subordinate object class. This structural object class is referred to as the structural object class of the entry."
There's a bit of ambiguity with this
"which has a single structural object class as the most subordinate object class"
What do you mean by 'most subordinate'? Is it that there must be no parallel entries at the same level in the hierarchy?

It's always better to provide a reference to the full text of a quoted text.
The hierarchy in this case is the the structural object classes hierarchy, not the directory information tree (DIT). Read in RFC 4512 about what SUP in object class description means:
http://tools.ietf.org/html/rfc4512#section-4.1.1
Note that there's also an attribute type hierarchy defined with SUP.
Ciao, Michael.

Yes, I know that.
Actually the question was --
What do you mean by 'most subordinate'? Is it that there must be no parallel structural object class at the same level in the class hierarchy?

Strange rule. Hard to believe. Thanks for clarifying.

It's not strange because DIT content rules, DIT structure rules and name forms can only be applied to a *single* strutcural object class.
That's also the reason why it's not allowed to change the structural object class. Because if DIT structure rules and name forms are in effect it could be necessary to also move the entry to another part of the DIT.

Ok, but I've another question related to this.
Suppose this is the superclass chain --
A -> B -> C -> D -> E -> F -> G
Then for D, the superclass chain is A -> B -> C, and in this chain D is the most subordinate. For F, the superclass chain is A -> B -> C -> D -> E and here too F is the most subordinate.
So what do you mean by the 'superclass chain'? The whole chain A to G or is it relative to a particular object class (because each object class at a different level will have a different superclass chain).

No.

Yes.
And other funny combinations by using multiple inheritance.
Ciao, Michael.

Yeah, now its clear. Thanks for that.

Not at all.
"which has a single structural object class as the most subordinate object class"

No.
This is talking about a hierarchy of classes, not a hierarchy of entries.
