#
# As of 2.0.0, FreeRADIUS supports virtual hosts using the
# \"server\" section, and configuration directives.
#
# Virtual hosts should be put into the \"sites-available\"
# directory. Soft links should be created in the \"sites-enabled\"
# directory to these files. This is done in a normal installation.
#
#
######################################################################
#
# Read \"man radiusd\" before editing this file. See the section
# titled DEBUGGING. It outlines a method where you can quickly
# obtain the configuration you want, without running into
# trouble. See also \"man unlang\", which documents the format
# of this file.
#
# This configuration is designed to work in the widest possible
# set of circumstances, with the widest possible number of
# authentication methods. This means that in general, you should
# need to make very few changes to this file.
#
# The best way to configure the server for your local system
# is to CAREFULLY edit this file. Most attempts to make large
# edits to this file will BREAK THE SERVER. Any edits should
# be small, and tested by running the server with \"radiusd -X\".
# Once the edits have been verified to work, save a copy of these
# configuration files somewhere. (e.g. as a \"tar\" file). Then,
# make more edits, and test, as above.
#
# There are many \"commented out\" references to modules such
# as ldap, sql, etc. These references serve as place-holders.
# If you need the functionality of that module, then configure
# it in radiusd.conf, and un-comment the references to it in
# this file. In most cases, those small changes will result
# in the server being able to connect to the DB, and to
# authenticate users.
#
######################################################################
#
# In 1.x, the \"authorize\", etc. sections were global in
# radiusd.conf. As of 2.0, they SHOULD be in a server section.

# need to setup hints for the remote radius server
