slapd configuration does not ask for olcbackend and doesn't add one. Has to be added by hand.

Installing slapd and ldap-utils results in missing backend

dn: olcBackend={0}mdb,cn=config

the installer skips the installation step. Has to be added by ldpamodify.

This was done intentionally as it's much more common to configure things
per-database than per-backend. What do you need the backend entry for,
and why is it a problem to add it yourself? Thanks.

I was just following the documentation on https://ubuntu.com/server/docs/service-ldap and there it is present. It still was on 19.10. So I was just wondering. Sorry!

Oh, I can fix that. Let me add a server-guide task.

[Andreas Hasenack (ahasenack)]

Just fixed, it might take a few minutes or hours to update on the site.

In that case, this is presumably Won't Fix for openldap, unless someone wants to start a discussion about that? Thank you to Mario for reporting, and Ryan for confirming the status.
