RE: (ITS#7228) Authentication Problem When Using PPolicy and Chaining
I believe the test is incorrect. Near the bottom of the script, there
is this section of code:
$LDAPSEARCH -H $URI2 -D "$USER" -w wrongpw >$SEARCHOUT 2>&1
$LDAPSEARCH -H $URI1 -D "$MANAGERDN" -w $PASSWD -b "$USER" \* \+ >>
COUNT=`grep "pwdFailureTime" $SEARCHOUT | wc -l`
echo "jkl 13"
if test $COUNT != 1 ; then
echo "Policy state forwarding failed"
test $KILLSERVERS != no && kill -HUP $KILLPIDS
The first LDAPSEARCH should have its return code checked, and for an
incorrect password, it should be 49. If the script is modified to check
for 49 and fail otherwise, it will fail.
Unfortunately, I am not in a position to use a newer version of
OpenLDAP, but I will build it and run the tests to see if the problem
exists there as well.
I will report back with my findings.

Unable to confirm this. Note that this is tested explicitly in test022
test suite, and no such behavior occurs there.
You're running a pretty old release, perhaps you should update.
unless you can provide more details to reproduce this situation, this
