I mean not the dn value (distinct for each record), but the string "dn"
itself.  The client already knows that "dn" attribute (that is, a kind
of id) will be prepended to a record, so naming it explicitly, and
including into the attributes list, is not that useful (and least it's
not what the original code meant).

I don't understand what you mean here..

I'm on macOS, OpenLDAP 2.6.4_1 from macports.  However, this string is
appended by Emacs itself.

I still stand by opinion that we should not touch emacs-29 here, due to
reasons I described in other messages.

Thanks.
