Well, actually I can try.
What will be the main goal of this edition?
to get it updated for latest kamailio stable version, 5.0.x.

Now I'm trying to find all features (about Radius) that have any influence on authentication process.
And one more question, is it possible to discuss the refurbish actions of the article not at sr-list, but in personal mailing?

Discussions on mailing list is better. I don't use RADIUS anymore, for many years, so I can't really help much on private.

Moreover, my inbox is not checked very often, it's a lot of unsolicited mail there. I rarely respond to emails there, unless I ask explicitly for some sensitive details and then have a filter on catching such messages. I check always the folders for mailing lists when I have a bit of time, when it's nothing do respond on mailing list, nothing to fix from bug tracker or nothing else to spend time on it, then I may get on the inbox -- in other words, it's very unlikely, that's why I send from time to time reminders here that writing private messages regarding kamailio have little chance to be answered - mailing lists are way better.

Cheers,
Daniel

What did you mean, when you ask for 'backend'?
If you meant an storage, so it's not a .txt users file, I'm using db - radcheck table.

So guys, the I've solved the problem.
It wasn't consisted of kamailio functions or radius configuration.

So you're free to use: www_challenge("$fd", "1"), until up radius_www_authorize("$fd","$fU") comes up.
Qop parameter does what he does and changes nothing within radius authentication process.


My problem was about username column in radcheck table.
It's not enough to insert an username, you ought to use full URI, like: username@my.proxy.domain
Also don't forget about attributes of the row that belongs to a certain user agent.

So my part of table for one of users looks like that:
;-------------------------------------------------------------------------------------------------------------------;
;---id---;---username-------;------attribute---------;------op-------;----------value---------------------;
;-------------------------------------------------------------------------------------------------------------------;
;__1__;__ua@dom.com_;__User-Password_;___==_____;_____hereuapassowrd____;
;__2__;__ua@dom.com_;__Auth-Type_____;___:=______;_____Digest____________;
;__....

Actually, I don't know why, but there is just a few articles all over the net, that describes a bit the functionality and processing with auth_radius module.
I hope my case will be useful for others, who uses kamailio + radius/db

But I have a problem how to request AVPs for a certain user from RADIUS, I found some solutions with SIP-AVP attribute, but still haven't done it.
Now I have to databases, one for Kamailio (that contains users AVPs, that Kamailio gets by avp_db_query) and second for users credentials (that are used while authorization on INVITE, REGISTER requests).

And as for the future, I have a goal to store passwords in ha1, haven't started to discover this.

Hi all.
Have a problem with radius authorization.

I'm using auth_radius.so

modparams, only path to client file:
modparam("auth_radius", "radius_config", "/etc/radiusclient/radiusclient.conf")

Freeradius installed and is working properly, radtest authentication from kamailio host succeed .

How authorization block looks like:

if (!is_present_hf("Authorization")) {
xlog("L_NOTICE", "----- Athorization HF is not found - passing the challenge -----\n");

if (nat_uac_test("2")) {
force_rport();
}

www_challenge("$fd", "1");
exit;


if (!radius_www_authorize("$fd","$fU")) {

if (nat_uac_test("2")) {
force_rport();
}
xlog("L_NOTICE", "----- Registeration $au@$ar ($fU) from $si:$sp Rejected. Code: $rc -----\n");

sl_send_reply("401","Unauthorized");
exit;

Radius log is filled by rows like:
Auth: [digest] Cleartext-Password or Digest-HA1 is required for authentication.

Tried to use radius_www_authorize without $fU - didn't change anything.
Tried to use www_challenge without qop - didn't change anything.

So, this solution is quite simple, but I have a fail while digest authentication.
Any ideas?
