slapo-allowed was modified between 2.4.21 and 2.4.22; support for allowedChildClasses and allowedChildClassesEffective was added.
The semantics you've implemented seems to be incompatible with my implementation in web2ldap which works correctly with MS AD. I do not claim to know the *exact* semantics of these attributes though.
web2ldap only uses the attribute 'allowedChildClasses'. In the object class select form web2ldap now only shows an empty list of STRUCTURAL object classes to be usable for a new entry. AUXILIARY object classes are shown. At first glance it seems STRUCTURAL object classes are not returned by slapo-allowed in the search result at all.
Since the main purpose of that overlay is to mimic AD, I think your observations make sense. I inferred the semantics of those attributes from the description I found in the links I was pointed to by Andrew Bartlett. My interpretation is that allowedChildClasses should list the objectClasses that can be added to a given entry; in my interpretation, these are all AUXILIARY objectClasses known to the DSA. The allowedChildClassesEffective are those objectClasses the identity is allowed to add by ACLs, and whose required attrs the identity is allowed to add by ACLs. Unless I made any coding mistake...
Hmm, aren't these attributes just for determinĆng the usable object classes when adding new entries (like poor man's DIT structural rules)?
In that case, slapo-allowed behavior would consist in listing all STRUCTURAL objectclasses.
In MS AD there are DIT content rules for limiting AUXILIARY object classes.
My interest in having this overlay exactly reproduce AD's behavior is close to zero. My main interest is in making OpenLDAP support Samba4 correctly, and the request for this feature was initially related to Samba4. As soon as I know for sure what those attributes are supposed to contain, then I think they should reflect that definition within OpenLDAP (e.g. an entry with any structural objectclass can be added as the child of any entry).
