+On peut décommenter la ligne qui va bien pour effacer les paramètres post_proxy au passage, en effet, il n'y a pas de raison de transmettre des informations tels que vlan id.
+===== Config de l'auth FedeRez =====
+On aurait très bien pu s'arréter ici, mais on souhaite permettre aux users FedeRez de s'auth avec un compte FedeRez. Ces comptes sont stockés dans le ldap.
+Par conséquent, on rempli le mods-available/ldap. En particulier, attention à bien faire du tls entre radius et ldap si le serveur ldap ou replica n'est pas sur localhost.

+On active ensuite le module ldap en faisant un lien symbolique dans mods-enabled. On vérifie que dans les sites il est bien fait référence à ldap (non commenté).
+==== Configuration des certificats ====
+Afin d'éviter d'utiliser des certificats auto-signés, on peut utiliser ceux générés par Let's Encrypt. Pour celà, on commence par créer des liens symboliques dans le dossier certs :
+<code>
+cd /etc/freeradius/3.0/certs
+ln -s /etc/letsencrypt/live/dodecagon.federez.net/cert.pem  cert.pem
+ln -s /etc/letsencrypt/live/dodecagon.federez.net/fullchain.pem  fullchain.pem
+ln -s /etc/letsencrypt/live/dodecagon.federez.net/privkey.pem server.key
+</code>
+On peut ensuite modifier la configuration de eap pour en tenir compte :
+<code>
+eap {
+        [...]
+            tls-config tls-LEcert {
+                private_key_file = ${certdir}/server.key
+                certificate_file = ${certdir}/cert.pem
+                ca_file = ${certdir}/fullchain.pem
+                dh_file = ${certdir}/dh
+                ca_path = ${cadir}
+                cipher_list = "DEFAULT"
+                cipher_server_preference = no
+                tls_min_version = "1.0"
+                tls_max_version = "1.2"
+                ecdh_curve = "prime256v1"
+                cache {
+                        enable = yes
+                        lifetime = 1 # hours
+                }
+                verify {
+                }
+                ocsp {
+                        enable = no
+                        override_cert_url = yes
+                        url = "http://127.0.0.1/ocsp/"
+                }
+        }
+        [...]
+        ttls {
+                tls = tls-LEcert
+        }
+        [...]
+        peap {
+                tls = tls-LEcert
+        }
+        [...]
+}
