Does OpenLDAP Support JNDI Event Notification?

1) Does OpenLDAP Support JNDI Event Notification of changes?  

I get OperationNotSupportedException when i Register listener for namespace change events.

Stack Trace of the Output:
javax.naming.OperationNotSupportedException: [LDAP: error code 12 - critical extension is not recognized]; remaining name 'cn=Sam'

2) What Directory Servers other than Sun ONE DS support JNDI Event notification

NOTE: It would be helpful if someone could give me some samples(JNDI Event Notification Programs).

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

another LDAP servers support Event notification is IBM Tivoli Directory Server,1322,1%253A482%253A429%253A26%253Aidpds,00.html#q26
