Searching for attributes indexed as type 'presence' does not
access the attribute index.

slapd.conf: index attr pres
Search filter: "attr=*"

log message:
  PRESENT
=> presence_candidates
=> index_read( "attr" "?" "*" )
<= index_read 8947 candidates (allids - not indexed)
<= presence_candidates 8947
<= filter_candidates 8947
<= list_candidates 8947
<= filter_candidates 8947
=> id2entry_r( 1 )
=> ldbm_cache_open( "/usr/local/ldbm-vadoe/id2entry.gdbm", 2, 600 )
<= ldbm_cache_open (cache 1)


The problem is in servers/slapd/back-ldbm/filterindex.c, in the
routine presence_candidates. A call is made to index_read with
an un-paramterized indexmask value ( 0 vs INDEX_PRESENCE ).

The patch (diff -c) is at:
