Asynchronous client notifications

[Colin Caughie <c.caughie@yibbish.net>]

Hello,

I'm considering using LDAP, and specifically OpenLDAP, for an 
application. One thing I need is to be able to respond fairly quickly to 
changes to the directory.

Ideally I'd like to be able to register a callback with the OpenLDAP API 
which will get called whenever a change is made, but I can't see a way 
to do this from looking at the man page for the API.

Is this at all possible? Does the LDAP protocol even support such things?

Thanks in advance,
Colin Caughie
