The command "configuration show" tries to redact some of the secrets
that are shown on the screen. However, this failed redacting options
that were marked as secrete by the auth plugins (if any) and it redacted
other options that were not redacted at all. For example, when using
the OpenID Connect plugins, it redacted the "access_token_endpoint" as
the word "token" appears there, but it failed to redact "client_secret"
even when this option is marked as secret in the corresponding plugin.
