Re: searching multiple backends

Absolutely not.  I said that if your X.500 DSA masters o=bar, it
cannot go asking somewhere else asking for a list of things directly
under o=bar and that doing *this* was bogus.  It *has* to know *what*
things are below (and since you brought up DNS, that's exactly how DNS
works).  If it knows that such and such things are mastered somewhere
else, then these are separate namingContexts.  Later I showed with
spec that, beyond my personal opinion, this is exactly what is
supposed to happen.  Unless the spec changes, your X.500 DSA has to
make separate searches for each delegated naming context.  Because an
LDAP server conformant to the spec is going to return a referral error
result if an attempt to search all of them in the same request is

In a different message you propose a glue entry and quickly hit the
referral loop problem and ask for slapd to break again the spec by not
returning the SearchResultReference entries (this is wrong, read 6.2
in RFC2251 where responsiblity for avoiding referral loops is placed
with the clients).

As you can see, there is no disagreement here.  But this says nothing
about the problem above.

No, your example talks about:

	#1 ou=foo,o=bar
	#2 ou=baz,o=bar
	#3 ou=fiz,o=bar

Unless there is also

	#n o=bar

mastered by that server, it should fail per the spec.  But if it
really were there, it seems it would fail too and that should not
happen, *this* is the bug.
