normally, user certs are password protected, and host certs are protected via
so in this context, the only requirement for GSI_DAEMON_CERT/GSI_DAEMON_KEY is
that the private key file is not encrypted with a password. in fact, you can
even use a user proxy as the host cert, since the user proxy is not pasword

you are correct. the FQDN is currently not extracted and matched with the IP.
this is something i will probably add, with a config option to disable it for
the reason you mentioned above.
