Subject RE: Exploring triggers
Date Thu, 02 Feb 2017 16:47:52 GMT
I was very close to having one working at some point in October or November, 
but couldn't quite get it. I created a class, uploaded the code into LDAP, 
and it was triggerable, but there didn't seem to be a way to they affect 
entries in the LDAP server.

The use case I was working on was using the addition of a user into a group 
triggering the application of a specific security policy.

this was an experiment, done a decade ago. We didn't had time to keep going, 
but the code is still present in the server.

There is some available material here :

It *has* worked, and I still do think it's a valuable feature.
Typically, that could be useful to manage users/group updates, or to trigger 
some code execution on updates.

Right now, I'm pretty sure it's not anymore working due to the migration 
from JNDI to the LDAP API (trigger code is still depending on JNDI, while 
teh rest of teh server depends on teh LDAP API). However, I don't think that 
reviving teh effort would take a lot of time, so if you are interested in 
it, I can drive you through the existing code.
