Hello
I'd need to trigger execution of an external shell script when some particular change occur in the tree. Is there a simple way of doing that?
Of course, an overlay could do that. I saw no available overlay that would have this capacity out of the box. The only way I see is building a new overlay just for that, or use something such as slapo-auditlog and feed it to an external filter (throug a pipe?). I wonder if there is a simplier mechanism available.

Although I kind of think a custom overlay would be cleaner, you could try replicating to a dummy server (like localhost:<off port>) running back-shell or back-perl and simply trigger there.

An alternative could be to use the slapo-accesslog(5) to log write operations, and use slapd-perl(5) as the logging database, so that write operations can be easily intercepted by a scripting backend without the hassle of setting up a replica.
Note that I haven't tried it, although it __should__ work.

If there is sufficient logging turned on, another approach is to watch $host:/var/log/messages for the event.
