Hi - these turn off security config options seem to be of dubious
value: ignoring common name mismatches and untrusted CAs both allow MITM

for any cert validation errors.


How often, though? Once per server? Once per ra-hitting command?
Currently it is an option which requires manual override within a
configuration file, and which can (and should) be overridden on a
server-by-server basis. If these are not enabled in the configuration
file, it is always a fatal connection error.

I would say once per ra session: by manual intervention I meant a
prompt in the user interface.

That will probably be a fair amount of work: a good first step would be
to add the config options to load trusted CA certs, and remove the calls
to ne_ssl_set_verify so that a cert verification error is always fatal.

I disagree - there is no real difference between having the user hit 'Y'
to get around a certificate problem, vs having the user to append
overrides to a file to get around a certificate problem. The only
difference really is that someone does not blindly hit 'Y' to continue,
which in my opinion makes it more secure, not less.
