The matched values has already been sent off for last call, and 
includes an appropriate note. I believe you should do likewise. Here 
is the matched values text


This control acts independently of other LDAP controls such as 
server 
side sorting [10] and duplicate entries [7]. However, there might be 
interactions between this control and other controls so that a 
different set of Search Result Entries are returned, or the entries 
are returned in a different order, depending upon the sequencing of 
this control and other controls in the LDAP request. For example, 
with server side sorting, if sorting is done first, and value return 
filtering second, the set of Search Results may appear to be in the 
wrong order since the value filtering may remove the attribute 
values 
upon which the ordering was done. (The sorting document specifies 
that entries without any sort key attribute values should be treated 
as coming after all other attribute values.) Similarly with duplicate 
entries, if duplication is performed before value filtering, the set 
of Search Result Entries may contain identical duplicate entries, 
each with an empty set of attribute values, because the value 
filtering removed the attribute values that were used to duplicate 
the results.
