Make EAP-Key-Name things work

#
#       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.
#
#       $Id$

######################################################################
#
#       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.

server default {
#
#  If you want the server to listen on additional addresses, or on
#  additionnal ports, you can use multiple "listen" sections.
#
#  Each section make the server listen for only one type of packet,
#  therefore authentication and accounting have to be configured in
#  different sections.
#
#  The server ignore all "listen" section if you are using '-i' and '-p'
#  on the command line.
#
listen {
        #  Type of packets to listen for.
        #  Allowed values are:
        #       auth    listen for authentication packets
        #       acct    listen for accounting packets
        #       proxy   IP to use for sending proxied packets
        #       detail  Read from the detail file.  For examples, see
        #               raddb/sites-available/copy-acct-to-home-server
        #       status  listen for Status-Server packets.  For examples,
        #               see raddb/sites-available/status
        #       coa     listen for CoA-Request and Disconnect-Request
        #               packets.  For examples, see the file

        type = auth

        #  Note: "type = proxy" lets you control the source IP used for
        #        proxying packets, with some limitations:
        #
        #    * A proxy listener CANNOT be used in a virtual server section.
        #    * You should probably set "port = 0".
        #    * Any "clients" configuration will be ignored.
        #
        #  See also proxy.conf, and the "src_ipaddr" configuration entry
        #  in the sample "home_server" section.  When you specify the
        #  source IP address for packets sent to a home server, the
        #  proxy listeners are automatically created.

        #  IP address on which to listen.
        #  Allowed values are:
        #       dotted quad (1.2.3.4)

        #       wildcard    (*)

        #  at the same time.
#       ipv6addr = ::   # any.  ::1 == localhost

        #  Allowed values are:

        port = 0

        #  Some systems support binding to an interface, in addition
        #  to the IP address.  This feature isn't strictly necessary,
        #  but for sites with many IP addresses on one interface,
        #  it's useful to say "listen on all addresses for eth0".

        #  set of clients.

        #  deal with overload situations.
        #
        #  The packets/s counter is tracked in a sliding window.  This
        #  means that the pps calculation is done for the second

#  Authentication.
#
#
#  This section lists which modules are available for authentication.
#  Note that it does NOT mean 'try each module in order'.  It means
#  that a module from the 'authorize' section adds a configuration
#  attribute 'Auth-Type := FOO'.  That authentication type is then
#  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),
#  or to or forcibly accept the user (Auth-Type := Accept).
#
#  Note that Auth-Type := Accept will NOT work with EAP.
#
#  Please do not put "unlang" configurations into the "authenticate"
#  section.  Put them in the "post-auth" section instead.  That's what
#  the post-auth section is for.
