Hi,
After analyzing the FreeRADIUS sources, I observed
that only 29 methods are supported. In other words, it
seems that the EAP-Type should be included in the
interval [1; 29]. This observation doesn't allow us to
use the Experimental EAP-Type whose value is 255
thanks to the RFC 2284bis.
A little modification of the sources allows FreeRADIUS
to manage the maximum number of EAP methods, e.g. 255.
The patch to apply is here below:
- In the eapcommon.c file, modify the
MAX_EAP_TYPE_NAME constant to 255 and the eap_types[]
array, which must have exactly 256 elements. Here is
an example of this array:
static const char *eap_types[] = {
"",
"identity",
"notification",
"nak", /* NAK */
"md5",
"otp",
"gtc",
"7",
"8",
"9",
"10",
"11",
"12",
"tls", /* 13 */
"14",
"15",
"16",
"leap", /* 17 */
"sim", /* 18 GSM-SIM authentication */
"19",
"20",
"ttls", /* 21 */
"22",
"23",
"24",
"peap", /* 25 */
"mschapv2", /* 26 */
"27",
"28",
"cisco_mschapv2", /* 29 */

"245","246","247","248","249",
"250","251","252","253","254",
"255"
};
- In the eap_types.h file, modify the PW_EAP_MAX_TYPES
constant to 255.
I agree that this solution is not optimal, e.g. we
have to declare 255 EAP-Types in order to use only the
EAP-Type 255 :-( But it works :-)
