OpenLDAP/ds-389 Secure Hardening Guide

in flag

I am in the process of setting up an Open Ldap Server (ds-389) however, I cannot find many good resources which define a security or hardening guide which can be applied to the configuration or schema of the directory.

Does anyone have any good links or references that discuss how we can appropriately harden an Open Ldap server configuration?

I found a few references, and an old CIS bench mark, but it seems CIS no longer provide a bench mark for Open LDAP.

Do you want to use OpenLDAP or 389-DS? Both are completely different LDAP servers.

Ideally 389-ds, but if you have something for open ldap i an happy to review that also.

The technical details differ a lot. I've implemented what I consider security best practices in [Æ-DIR](https://ae-dir.com) which is basically an IAM baed in [OpenLDAP](https://www.openldap.org). See also my talk at ODD 2018 [Defense in Depth: Hardening an OpenLDAP deployment](https://www.openldap.org/conf/odd-tuebingen-2018/Michael1.pdf) about OS-side hardening (besides all the OpenLDAP config stuff). Being the author I'm biased of course.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
