#6869 CA-less pkinit not installable with --pkinit-cert-file option
Closed: fixed 6 years ago Opened 7 years ago by stlaz.

Closed: fixed
Reopen Issue

When installing PKINIT cert in CA-less installation and using the --pkinit-cert-file option, the installation always fails.

The reason the installation fails is that we require full chain in the .p12 file that's fed to the above option. The file gets correctly exported to a PEM bundle in '/var/kerberos/krb5kdc/kdc.crt' but it will contain multiple certificates. OpenSSL does not know how to deal with this, it assumes there's only one certificate in the PEM file. If the first certificate is a CA cert, that will cause the installation to crash as it will be unable to test anonymous pkinit.

Indeed, kinit -n gives:
