#       $ radtest USER PASSWORD 127.0.0.1:18120 0 testing123
#
#  If it works, you have configured the inner tunnel correctly.  To check
#  if PEAP will work, use:
#
#       $ radtest -t mschap USER PASSWORD 127.0.0.1:18120 0 testing123
#
#  If that works, PEAP should work.  If that command doesn't work, then
#
#       FIX THE INNER TUNNEL CONFIGURATION SO THAT IT WORKS.
#
#  Do NOT do any PEAP tests.  It won't help.  Instead, concentrate
#  on fixing the inner tunnel configuration.  DO NOTHING ELSE.

        #
        #  If you are using multiple kinds of realms, you probably
        #  want to set "ignore_null = yes" for all of them.
        #  Otherwise, when the first style of realm doesn't match,
        #  the other styles won't be checked.

        #  Note that proxying the inner tunnel authentication means
        #  that the user MAY use one identity in the outer session
        #  (e.g. "anonymous", and a different one here
        #  (e.g. "user@example.com").  The inner session will then be
        #  proxied elsewhere for authentication.  If you are not
        #  careful, this means that the user can cause you to forward
        #  the authentication to another RADIUS server, and have the
        #  accounting logs *not* sent to the other server.  This makes
        #  it difficult to bill people for their network activity.

        #  next few lines ensure that the request is not proxied.

        #  The example below uses module failover to avoid querying all
        #  of the following modules if the EAP module returns "ok".
        #  Therefore, your LDAP and/or SQL servers will not be queried

#  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 appropriate 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, or forcibly accept him.

#  Once we KNOW that the user has been authenticated, there are

#  authentication methods.

#  the ONLY safe way is to set "use_tunneled_reply = yes", and
#  then update the inner-tunnel reply.
