asynchronous event notification

["David J. Ferrero" <david.ferrero@zion.com>]

I'm working on a OpenLdap/JNDI application and had plans to register for
namespace and object content change events (add, remove, rename,
change). Ie: I'd like for the application to be notified when a new
entry is made to openldap or removed or changed or renamed. From a
cursory scan through JNDI: javax.naming.event.* and javax.naming.ldap.*
packages it appears that these are LDAP v3 features and probably doesn't
exist in OpenLDAP 1.X but maybe would be available in OpenLDAP 2.X

Could someone with more intimate knowledge of LDAP v2 vs. v3 spec and
OpenLDAP development or JNDI w/OpenLDAP care to comment on above with
regard to registering for unsolicated events and asynchronous event
notifications?

I could probably just as easily develop another form of communication
between the producer and consumer applications but would rather use LDAP
events if available.

Any quick response is appreciated as this is under development now.
