TLS connection with freeradius and openssl
In first, sorry for my english, I'm a baguette man.
I would like to make an EAP-TLS connection for wifi. I use freeradius for the authentification and Openssl for create certificates. So first I "create" a root-ca.key, then a root-ca.req and the a root-ca.crt. Then i do the same for the user certificate and sign the user's certificate with the root-ca. Then i change my freeradius with the correct certificates name in /etc/freeradius/3.0/mods-enable/eap and I install root-ca and and the user certificate on my phone. But, when i run freeradius in debug mode, it say "eap_tls: ERROR: TLS Alert read:fatal:unknown CA".
My conf
/etc/freeradius/3.0/mods-enable/eap

#}
# Cisco LEAP
#
# We do not recommend using LEAP in new deployments. See:
# http://www.securiteam.com/tools/5TP012ACKE.html
#
# Cisco LEAP uses the MS-CHAP algorithm (but not
# the MS-CHAP attributes) to perform it's authentication.
#
# As a result, LEAP *requires* access to the plain-text
# User-Password, or the NT-Password attributes.
# 'System' authentication is impossible with LEAP.
#
#leap {
#}
# 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.
#
#gtc {
# The default challenge, which many clients
# ignore..
#
# challenge = "Password: "
# 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.
#
#auth_type = PAP

# Common TLS configuration for TLS-based EAP types
# ------------------------------------------------
#
# See raddb/certs/README 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 = 1234
private_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
# 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_dir", 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.
#

# Trusted Root CA list
#
# This file can contain multiple CA certificates.
# ALL of the CA's in this list will be trusted to

#
# 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 = /etc/ssl/certs/ca-certificates.crt
# 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. As of
# 3.0.18, 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}'}"

In this conf, i use the default openssl's certificates. But it's the same problem when i make my own certificates. I tried every tuto on internet but nothing.
If you need more informations, i will give it to you !

hope you solved it, but just for the lonely admin walking by, I assume your problem lies within the following line:
auto_chain = yes
Change it to
auto_chain = no
Otherwise, your freeradius server will try to chain the certificate, referred to under ca_file to the certificates present in the operating system.
