The generated certificates have been X.509 v1. This is not supported any
more. Only X.509 v3 is supported.
A new certificates/extensions.conf file has been added to make v3
certificates.
The existing certificates/pkinit/extensions.conf has been renamed to
certificates/pkinit-extensions.conf with additional changes. For example
"[kdc_cert]" had to be removed for v3.
The extensions config files are using environment variables, which are
set by the generate-certificates.sh script before calling openssl.
The script generate-certificates.sh has been reworked for a simpler
structure, also new options have been added: "ca" and "cleanup".
The certificates should not be pre-generated as they will expire at some
point. Simply generate them for each test run using the domain used in the
test. Copy the certificate files each time into the test server after
removing the old ones.
