Add a `lifetime=NUMunit` query parameter.
Also add a krb5.conf parameter to indicate whether this is allowed.
We already have a max lifetime configuration parameter.
A HEAD or GET of / or /health will now produce a 200 instead of a 404.
Ideally we should add configuration arguments that would allow /health
to get a token, make a CSR, and test the /bx509 (and/or /bnegotiate)
functionality, that way we'd have a real health check. For now we defer
that work, as external health monitoring can be done using a simple
script anyways.
Now we'll put the "reason=..." last in the log lines and we won't escape
spaces -- just newlines and other control characters. This makes
reading log lines much easier without complicating parsing of log lines
because interior key=value pairs do get whitespace escaped or removed.
