Changelog for OpenLdap


Hi,
I have a ldap driver that is conneted to an OpenLdap server from IDM,
thus changes in IDM vault are written to the OpenLdap server.
Because another driver has access to create objects in the OpenLdap
server, I want the ldap driver to raise an event in publisher channel
whenever an object has changed or created in the OpenLdap server.
The ldap driver should then somehow trigger a resync in the subscriber
channel afterward. There are 2 publisher options:

1. Ldap search method, which is very slow and does not support
loopback prevention
2. Changelog overlay contributed by Sebastian Rieger.

What is your experience with the changelog option? Is it stable? is it
scalable? Good performance?

Best regards
Thanh

Use changelog.

Why? Via what logic do you want a resync to happen?

That'd be a question for the OpenLDAP community, I guess.

While I don't have recent direct experience I've heard that it performs adequately for most applications.
I used it 10 ish years ago and it worked fine for changes to a 10K object directory. In theory it hasn't gotten worse 🙂

That sounds great. I have a 30k+ object directory that I want to apply
the changelog on, and the size of the directory increases each day. So
performace has a big impact. Right now I'm trying to get the module
installed.
The latest version I have seen so far is version 2.4.21:

Do any of you know if there exists a newer version?

Best regards
Thanh

The latest openldap version appears to be 2.4.40. I would look there.
