Voici des extraits détaillés de la configuration RADIUS de FDN, et un exemple SQL:

huntgroups:

td NAS-IP-Address == 80.119.0.0
td NAS-IP-Address == 80.119.0.1

...

users:

DEFAULT Huntgroup-Name == 'td', Auth-Type := td
      Service-Type:1 := "Framed",
      Framed-Protocol:1 := "PPP",
      Class:1 := 0,
      Tunnel-Type:1 := "L2TP",
      Tunnel-Medium-Type:1 := "IP",

Voici un extrait des tables SQL:

mysql> select * from RADUSER where RADUSER_LOGIN='jeannot.lapin@fdn.nerim';
+------------+-------------------------+-------------+----------+
| RADUSER_ID | RADUSER_LOGIN           | RADGROUP_ID | LIGNE_ID |
+------------+-------------------------+-------------+----------+
|        111 | jeannot.lapin@fdn.nerim |           1 |      154 |
+------------+-------------------------+-------------+----------+
1 row in set (0.00 sec)
mysql> select * from UATTR where RADUSER_ID=111;
+----------+-------------------+----------+--------------------+------------+------------+
| UATTR_ID | UATTR_ATTR        | UATTR_OP | UATTR_VALUE        | UATTR_TYPE | RADUSER_ID |
+----------+-------------------+----------+--------------------+------------+------------+
|      362 | User-Password     | ==       | toto               | check      |        111 |
|      363 | Framed-IP-Address | =        | 80.67.176.89       | reply      |        111 |
|      364 | Framed-IP-Netmask | =        | 255.255.255.255    | reply      |        111 |
|      389 | Framed-IPv6-Route | =        | 2001:910:1059::/48 | reply      |        111 |
+----------+-------------------+----------+--------------------+------------+------------+
4 rows in set (0.00 sec)

Et par exemple, ça donne donc:

$ radtest jeannot.lapin@fdn.nerim toto 80.67.169.40 1 pweeet ppp 80.67.169.42
Sending Access-Request of id 44 to 80.67.169.40 port 1812
	User-Name = "jeannot.lapin@fdn.nerim"
	User-Password = "toto"
	NAS-IP-Address = 80.67.169.42
	NAS-Port = 1812
	Message-Authenticator = 0x00000000000000000000000000000000
      Framed-Protocol = PPP
rad_recv: Access-Accept packet from host 80.67.169.40 port 1812, id=44, length=52
	Framed-IP-Address = 80.67.176.89
	Framed-IP-Netmask = 255.255.255.255
	Framed-IPv6-Route = "2001:910:1059::/48"
