Hi,

I'll shortly answer to your questions:
1) All the handler receive a LDIF or DSML stream. More in deep it
will receive the format specified in the associated policy object by
the 'dataFormat' field.

1.3.6.1.4.1.24119.1.0.1.2.2.1 NAME 'policy'
                DESC 'Event Manager policy entry'
                SUP top ABSTRACT
                MUST ( cn $ dataFormat )
                MAY ( userPassword $ description $ searchBase $
                searchFilter $ searchAttribute $ active $
                autostart $ command $ logLevel $ writeAttribute $
                createEvent $ modifyEvent $ deleteEvent ) )

2) Yes, both LDIF and DSML in case of delete, modify or modrdn
provides old and new values.
A ldapmodify of:

dn: uid=mosaico,ou=people,o=H4T,c=IT
changetype: modify
delete: givenName
-
replace: sn
sn: Mosaico

will pass to the handler the following DSML:

<?xml version="1.0" encoding="UTF-8"?>
<batchRequest xmlns="um:oasis:tc:DSML:2:0:core">
  <modifyRequest dn="uid=mosaico,ou=people,o=H4T,c=IT">
    <modification name="givenName" operation="delete">
      <value>Mosaico</value>
    </modification>
    <modification name="sn" operation="delete">
      <value>Gestionale</value>
    </modification>
    <modification name="sn" operation="add">
      <value>Mosaico</value>
    </modification>
  </modifyRequest>
</batchRequest>

3) Yes. The collection of events, the filter of relevant events for
the policies and the handling of them are done by separated threads.
All transparent from LDAP server.
OpenLDAP manage operations as a kind of transaction, so if there are
no bugs in the locking interaction from the overlay and the server
backends the consistence is guaranteed.
