I'm getting through a lot of trouble in understanding the whole AUXILIARY/STRUCTURAL inheritance definition on a ldif, and the syntax that is needed for the correct definition. Ex. snip ---->> objectclass ( 1.3.6.1.4.1.15490.2.1 NAME 'objCollege' SUP top STRUCTURAL DESC 'object class' MUST (collegeName $ collegePrincipal $ collegePresident $ collegeSecretary ) MAY (collegeBoardMember ) ) dn: o=college o: college objectclass: organization objectclass: objCollege objectclass: top Description: top object class collegeName: ABC Engineering college ... and the rest follows? ---->><<< wouldn't it be the same as dn: o=college objectclass: top objectclass: organization objectclass: objCollege o: college Description: top object class ... >> and the rest follows .???

  On the last line of page 1 of this article, I state:
  
  "I've done it starting with top and listing the descendants in order, like a family tree. You're free to list them out of order if you like."
  
  That is not to say that I condone listing things out of order - I don't. However, I'm unsure that there is a product that will enforce this ordering of objectclasses in a given entry.
  
  If the product you're using does not enforce the ordering, then the answer to your question "aren't these the same?" is "yes". If your product *does* care about the ordering, then the answer is "no", and you'll have to reorde the objectclass attributes of the entry.
  
  If you're unsure how to do that, re-read this article, and you should be able to figure it out. If not, list your questions here! :-)

  Gotcha for the objectclass ordering, Tks, and what about the o: after the dn: or after the objectclass tree, is it the same "doesn't make a difference" if the ldapadd uderstands it?

  it's never made a difference on any system I've seen. I'm just anal retentive that way and like things to be orderly. Truthfully, you'll find that no matter how much of a stickler you are, attributes *can* be returned by the server in more or less random order anyway, so... go figure.
