Hi,

I'm not sure I understood all of your problem, but here are some
information that may help:
- First, you don't change a certificate, but you can revoke it a make a new
one
- If you need to add a SubjectAltName to a certificate, you may have
realized that the -D parameter makes the request to get rejected by FreeIPA
when you try this:

ipa-getcert request -d $NSSPATH -n $CERTNAME -p $PWDFILE -N
"CN=$FQDN,O=$DOMAIN" -D "$CNAME" -K $PRINCIPAL

You have to force FreeIPA to recognise the CNAME first.

$ ipa host-add cname.domain --force
$ ipa service-add service/fqdn
$ ipa service-add service/cname.domain --force
$ ipa service-add-host service/cname.domain --host fqdn

Then the ipa-getcert request will work.

I hope it helps (you or anyone else needing a subjectaltname in a
certificate).
Cheers,
