Hi,
I just upgraded our servers from Debian 11 to 12. I'm not sure if this
is an upstream change, but slapd 2.5 on Debian 12 doesn't support the
HDB and BDB backends, so the database needs to be migrated to LMDB.
Unfortunately I neglected to check the backend in use for all instances.
Our main slapd instance already used LMDB, but another instance, that's
just getting a copy of that database through sync replication, was still
using HDB. At first I only noticed an error during upgrade. I found a
guide
(https://sources.debian.org/src/openldap/2.5.13%2Bdfsg-5/debian/slapd.README.Debian/
line 255 following) to do the upgrade to 2.5.x if it fails, which showed
me the error.
lt_dlopenext failed: (back_hdb) file not foundslapadd: could not add
entry dn="cn=module{0},cn=config" (line=16): <olcModuleLoad> handler
exited with 1
Closing DB...
So I followed the setps under "BDB/HDB backends removed: migrating to
LMDB backend". But upon trying to restore the backup again, it just told me
slapadd: could not add entry dn="cn=config" (line=1):
Closing DB...
The first set of lines in cn\=config.ldif reads

So I'm not sure what it wants to tell me now. I already checked against
the config of the main instance, made a few modifications, but the error
message is the same. Here the modifications:

Could anybody tell me what exactly the problem is?
