That particular case sounds like you were missing the "aci" attribute 
which is an operational attribute.

In general, if you want "everything"(1), you can do a search like this:

ldapsearch -b dc=your,dc=suffix 
'(|(objectclass=*)(objectclass=ldapsubentry))' \* $OPERATIONAL_ATTRS

where $OPERATIONAL_ATTRS is a list of operational attributes you can get 
from the schema.  You'll definitely want "aci" in that list.

If you know python, python-ldap has a nice schema parser.

(1) This still won't get you everything - specifically, you won't get 
deleted entries and other replication metadata - If you think you need 
that information, add (objectclass=nsTombstone) to the search filter above.
