I was trying to define the posixGroup2 object class in OpenDJ, and the server refuses it because we do not allow to define a structural objectClass that inherits from auxiliary objectClasses.

And this is the proper behavior as RFC4512, section 2.4.2 specifically calls it:

<quote>
 Structural object classes cannot subclass auxiliary object classes.
</quote>

Regards,

Ludo

+1  

Could you please go ahead pushing draft-findlay-ldap-groupofentries?

That's exactly how I see it.  

Ciao, Michael.
