This bug was fixed in the package openldap - 2.6.3+dfsg-1~exp1ubuntu2
---------------
openldap (2.6.3+dfsg-1~exp1ubuntu2) lunar; urgency=medium
* Build the passwd/sha2 contrib module with -fno-strict-aliasing to
avoid computing an incorrect SHA256 hash with some versions of the
compiler (LP: #2000817):
- d/t/{control,sha2-contrib}: test to verify the SHA256 hash
produced by passwd/sha2
- d/rules: set -fno-strict-aliasing only when building the
passwd/sha2 contrib module
* d/t/smbk5pwd: Allow the openldap user to read the Heimdal master key in the
smbk5pwd DEP8 test (LP: #2004560)

I reproduced this in a container, and the failure is two-fold:
a) /var/lib/heimdal-kdc/ is root:root 0700, and the slapd server needs
FS read access to the key
b) Then the slapd apparmor profile blocks it:
[qui fev 2 09:54:02 2023] audit: type=1400 audit(1675342444.436:3242):
apparmor="DENIED" operation="open" class="file"
