[Bug] TLS certificate can't be created if the directory for private key is specified

[vasilevalex]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7.28.0
• Ruby: 2.7.8
• Distribution: Rocky Linux 8.9
• Module version: 3.1.0

How to reproduce (e.g Puppet code you use)

Try to create self-signed certificate with parameter key_dir, for example:

openssl::certificate::x509 { $facts[networking][fqdn]:
    country      => 'DK',
    state        => 'Denmark',
    locality     => 'Test',
    commonname   => $facts[networking][fqdn],
    organization => 'company A/S',
    unit         => 'test',
    email        => 'admin@test.dk',
    days         => 3650,
    base_dir     => '/etc/ssl/certs',
    key_dir      => '/etc/ssl/private',
    force        => false,
    encrypted    => false,
  }

What are you seeing

X509_cert is trying to use default key from the same directory with the request and certificate (/etc/ssl/certs). The key is generated in correct directory (/etc/ssl/private)

What behaviour did you expect instead

X509_cert must use the signing key from the parameter key_dir (/etc/ssl/private)
