Subject: [PATCH] Test client performs Post-Handshake-Authentication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This test uses openssl tool because PHA is not yet supported by
IO::Socket::SSL's server implementation. The openssl tool uses a fixed
port. So the test can fail.
