Hi! forgive a beginner's question, but: If I examine cn=Subschema, I see the following object classes: objectClass[0] top objectClass[1] subentry objectClass[2] subschema objectClass[3] extensibleObject And among the attributes is ldapSyntaxes. ldapSyntaxes however is not part of subentry or subschema; according to the schemata presented, ldapSyntaxes is only part of olcGlobal and olcSchemaConfig. So should cn=Subentry have olcSchemaConfig as auxiliary object class? And in which object class should structuralObjectClass (and things like createTimestamp) belong? Regards, Ulrich
