Optionally validate certificates on TLS server links

#
# This is a sample configuration file for the ngIRCd IRC daemon, which must
# be customized to the local preferences and needs.
#
# Comments are started with "#" or ";".
#
# A lot of configuration options in this file start with a ";". You have
# to remove the ";" in front of each variable to actually set a value!
# The disabled variables are shown with example values for completeness only
# and the daemon is using compiled-in default settings.
#
# Use "ngircd --configtest" (see manual page ngircd(8)) to validate that the
# server interprets the configuration file as expected!
#
# Please see ngircd.conf(5) for a complete list of configuration options
# and their descriptions.
#

[Global]
        # The [Global] section of this file is used to define the main
        # configuration of the server, like the server name and the ports
        # on which the server should be listening.
        # These settings depend on your personal preferences, so you should
        # make sure that they correspond to your installation and setup!

        # (".") and be unique in the IRC network. Required!
