# 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.
#
# If you are using 802.1X (EAP) authentication, please see also
# the "inner-tunnel" virtual server. You wll likely have to edit
# that, too, for authentication to work.

# 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.

# This section lists which modules are available for authentication.

# used to pick the apropriate module from the list below.
#
# In general, you SHOULD NOT set the Auth-Type attribute. The server
# will figure it out on its own, and will do the right thing. The
# most common side effect of erroneously setting the Auth-Type
# attribute is that one authentication method will work, but the
# others will not.
#
# The common reasons to set the Auth-Type attribute by hand
# is to either forcibly reject the user (Auth-Type := Reject),

#
# Note that Auth-Type := Accept will NOT work with EAP.
