In Event Broker v188.8.131.52, the default LDAP filter for the AD Changes plugin, according to the plugin description, should be:
(& amp ;(objectClass=user)(objectCategory=person))
Instead, it is:
(& amp ; amp ;(objectClass=user)(objectCategory=person))
This results in the plugin never detecting changes. This is easily fixed by updating the LDAP filter and removing the additional "amp;".
I believe this may be already incorporated into Event Broker v3
