+++ This bug was initially created as a clone of Bug #729378 +++

setup windows sync to have a sub-container entry for users e.g.
dn: cn=testusers,cn=users,dc=example,dc=com
objectclass: top
objectclass: container
cn: testusers

You can use ldapmodify or (on Windows) Run->adsiedit.msc

Setup windows sync to use cn=testusers,cn=users,dc=example,dc=com as the AD subtree (and use ou=people,dc=example,dc=com or whatever on the DS side) - make sure to set up SSL too in order to test syncing password changes from DS to AD (setting up PassSync is not required) - make sure the sync agreement uses SSL or TLS

Make sure sync is working - e.g. add a user to one side and make sure it syncs to the other side

on the AD side, remove the user entry and the sub-container entry - immediately after this, do an ldap modify operation for the userPassword of the DS user - you should see a crash in the DS shortly thereafter
