I am running FreeIPA 4.9.8 as a Docker container and Firefox refuses the certificate as
the serial has been reused. I found this post:
https://bugzilla.redhat.com/show_bug.cgi?id=747959 and this post:
https://galenabell.com/2018/10/23/random-certificate-serials-in-freeipa/, but the files
mentioned do no longer exist in FreeIPA 4.9.8 (or I cannot find them).
I tried adding:
```
PKI_RANDOM_SERIAL_NUMBERS_ENABLED="true"
export PKI_RANDOM_SERIAL_NUMBERS_ENABLED
```
to /usr/share/pki/etc/pki.conf
and I tried adding PKI_RANDOM_SERIAL_NUMBERS_ENABLED=TRUE as environment variable in the
docker-compose file. Neither worked. During install I see the variable being set to false
in the logs.
Any suggestion on how to have random serials after an unattended install?
