#
# EAP-GTC -- Generic Token Card
#
# Currently, this is only permitted inside of EAP-TTLS,
# or EAP-PEAP. The module "challenges" the user with
# text, and the response from the user is taken to be
# the User-Password.
#
# Proxying the tunneled EAP-GTC session is a bad idea,
# the users password will go over the wire in plain-text,
# for anyone to see.

# The plain-text response which comes back
# is put into a User-Password attribute,
# and passed to another module for
# authentication. This allows the EAP-GTC
# response to be checked against plain-text,
# or crypt'd passwords.
#
# If you say "Local" instead of "PAP", then
# the module will look for a User-Password
# configured for the request, and do the
# authentication itself.

# Common TLS configuration for TLS-based EAP types
# ------------------------------------------------
#
# See raddb/certs/README.md for additional comments
# on certificates.
#
# If OpenSSL was not found at the time the server was
# built, the "tls", "ttls", and "peap" sections will
# be ignored.
#
# If you do not currently have certificates signed by
# a trusted CA you may use the 'snakeoil' certificates.
# Included with the server in raddb/certs.
#
# If these certificates have not been auto-generated:
# cd raddb/certs
# make
#
# These test certificates SHOULD NOT be used in a normal
# deployment. They are created only to make it easier
# to install the server, and to perform some simple
# tests with EAP-TLS, TTLS, or PEAP.
#
# Note that you should NOT use a globally known CA here!
# e.g. using a Verisign cert as a "known CA" means that
# ANYONE who has a certificate signed by them can
# authenticate via EAP-TLS! This is likely not what you want.
#
tls-config tls-common {
private_key_password = whatever
private_key_file = ${certdir}/server.pem
# If Private key & Certificate are located in
# the same file, then private_key_file &
# certificate_file must contain the same file
# name.
#
# If ca_file (below) is not used, then the
# certificate_file below SHOULD also include all of
# the intermediate CA certificates used to sign the
# server certificate, but NOT the root CA.
#
# Including the ROOT CA certificate is not useful and
# merely inflates the exchanged data volume during
# the TLS negotiation.
#
# This file should contain the server certificate,
# followed by intermediate certificates, in order.
# i.e. If we have a server certificate signed by CA1,
# which is signed by CA2, which is signed by a root
# CA, then the "certificate_file" should contain
# server.pem, followed by CA1.pem, followed by
# CA2.pem.
#
# When using "ca_file" or "ca_path", the
# "certificate_file" should contain only
# "server.pem". And then you may (or may not) need
# to set "auto_chain", depending on your version of
# OpenSSL.
#
# In short, SSL / TLS certificates are complex.
# There are many versions of software, each of which
# behave slightly differently. It is impossible to
# give advice which will work everywhere. Instead,
# we give general guidelines.
#
certificate_file = ${certdir}/server.pem
# Trusted Root CA list
#
# This file can contain multiple CA certificates.
# ALL of the CA's in this list will be trusted to
# issue client certificates for authentication.
#
# In general, you should use self-signed
# certificates for 802.1x (EAP) authentication.
# In that case, this CA file should contain
# *one* CA certificate.
#
ca_file = ${cadir}/ca.pem

# Directory where multiple CAs are stored. Both
# "ca_file" and "ca_path" can be used at the same time.
#
ca_path = ${cadir}
# OpenSSL does not reload contents of ca_path dir over time.
# That means that if check_crl is enabled and CRLs are loaded
# from ca_path dir, at some point CRLs will expire and
# the server will stop authenticating users.
#
# If ca_path_reload_interval is non-zero, it will force OpenSSL
# to reload all data from ca_path periodically
#
# Flush ca_path each hour
# ca_path_reload_interval = 3600
# OpenSSL will automatically create certificate chains,
# unless we tell it to not do that. The problem is that
# it sometimes gets the chains right from a certificate
# signature view, but wrong from the clients view.
#
# When setting "auto_chain = no", the server certificate
# file MUST include the full certificate chain.
#
# auto_chain = yes
# If OpenSSL supports TLS-PSK, then we can use a
# fixed PSK identity and (hex) password. These can
# be used at the same time as the certificate
# configuration, but only for TLS 1.0 through 1.2.
#
# If PSK and certificates are configured at the same
# time for TLS 1.3, then the server will warn you,
# and will disable TLS 1.3, as it will not work.
#
# The work around is to have two modules (or for
# RadSec, two listen sections). One will have PSK
# configured, and the other will have certificates
# configured.
#
# psk_identity = "test"
# psk_hexphrase = "036363823"
# Dynamic queries for the PSK. If TLS-PSK is used,
# and psk_query is set, then you MUST NOT use
# psk_identity or psk_hexphrase.
#
# Instead, use a dynamic expansion similar to the one
# below. It keys off of TLS-PSK-Identity. It should
# return a of string no more than 512 hex characters.
# That string will be converted to binary, and will
# be used as the dynamic PSK hexphrase.
#
# Note that this query is just an example. You will
# need to customize it for your installation.
#
# psk_query = "%{sql:select hex(key) from psk_keys where keyid = '%{TLS-PSK-Identity}'}"
# For DH cipher suites to work in OpenSSL < 1.1.0,

#
# This check is done only if the previous
# "check_cert_issuer" is not set, or if

# This configuration item only applies when there is
# an intermediate CA between the "root" CA, and the

# intermediate CA can issue client certificates, and
# have them accepted by the EAP module.
#
# The solution is to list ONLY the trusted CAs in the
# FreeRADIUS configuration, and then set this
# configuration item to "yes".
#
# Then, when the server receives a client certificate
# from an untrusted CA, that authentication request
# can be rejected.
#
# It is possible to do these checks in "unlang", by
# checking for unknown names in the
# TLS-Cert-Common-Name attribute, but that is
# more complex. So we add a configuration option
# which can be set once, and which works for all

# Generally speaking you should NOT use TLS 1.0 or

# We recommend replacing those legacy systems, and
# using at least TLS 1.2.
#
# Some Debian versions disable older versions of TLS,
# and requires the application to manually enable
# them.
#
# If you are running such a distribution, you should
# set these options, otherwise older clients will not
# be able to connect.
#
# Allowed values are "1.0", "1.1", "1.2", and "1.3".
#
# As of 2021, it is STRONGLY RECOMMENDED to set
#
# tls_min_version = "1.2"
#
# Older TLS versions are insecure and deprecated.
#
# In order to enable TLS 1.0 and TLS 1.1, you may

#
# While the server will accept "1.3" as a value,
# most EAP supplicants WILL NOT DO TLS 1.3 PROPERLY.
#
# i.e. they WILL NOT WORK, SO DO NOT ASK QUESTIONS ON
# THE LIST ABOUT WHY IT DOES NOT WORK.
#
# The TLS 1.3 support is here for future
# compatibility, as clients get upgraded, and people

#
# The "Cached-Session-Policy" is the name of a
