dupent and filters

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

How does dupent interact with filters?  Are entries:
	1) dup'ed then matched
	2) matched then dup'ed

That is, given a entry within scope of the search:
	dn: cn=foo, o=bar
	cn: foo
	cn: bar
	...

The filter is (cn=foo) and critical dupent w/ attrs of cn.

Should their be one dup-entry or two dup-entries returned?
I would assume that the returned duplicate entries would
each match the filter.  Hence 1). above.  Of course,
implementors would likely want to match then dup
then match to avoid unnecessary dup'ing.

Anyways, whether 1 or 2, the behavior should be spelled out.
