Yes. And I learnt it hard way this time - couple of days of debug-like work.
It turned out that group checking entries in Radius configs need to be
before any user specific ones - generally speaking.
SER module works correctly all the way (in my experience).
Thanks for your indication though.

Hi Velimir,
not an expert on RADIUS, but my guess the problem is in the RADIUS
server configuration - it should not request authentication for the
"Service-Type = Group-Check"

Hi,
I run SER with Radius/MySQL for authentication and accounting.
Things are pretty much in place except for group checking. I have
something like this in my ser.cfg:
....
modparam("auth_radius", "radius_config",
"/etc/radiusclient-ng/radiusclient.conf")
modparam("group_radius", "use_domain", 1)
.....
if (uri=~"^sip:[0-9]{8}@") { # Domestic PSTN
if (!radius_is_user_in("credentials", "ld")) {
sl_send_reply("403", "No permission for domestic calls");
return;
};
route(4);
return;
};
....
When I look at Radius debug log I can see that when ser sends a
request to radius, radius wants to do digest on it and then the
complete request fails and call can't go through. Output looks
something like this:
..
rad_recv: Access-Request packet from host 127.0.0.1:34027, id=18,
length=72
User-Name = "81000(a)sage.home.local"
Sip-Group = "voicemail"
Service-Type = Group-Check
NAS-Port = 0
NAS-IP-Address = 127.0.0.1
Processing the authorize section of radiusd.conf
..
** bunch of sql statements ...
..
modcall: group authorize returns ok for request 17
rad_check_password: Found Auth-Type Digest
auth: type "digest"
Processing the authenticate section of radiusd.conf
modcall: entering group authenticate for request 17
ERROR: No Digest-Nonce: Cannot perform Digest authentication
modcall[authenticate]: module "digest" returns invalid for request 17
modcall: group authenticate returns invalid for request 17
auth: Failed to validate the user.
In databases I have following:
mysql> SELECT id,UserName,Attribute,Value,op FROM radreply WHERE
Username = '81000(a)sage.home.local' ORDER BY id;
+----+-----------------------+--------------+-------------+----+

roupName ORDER BY radgroupcheck.id;
+----+-----------+-----------+--------+----+
| id | GroupName | Attribute | Value | op |
+----+-----------+-----------+--------+----+

+----+-----------+-----------+--------+----+
Has anyone had a chance to do something like this with success? I am
stuck at the moment - any help is greatly appreciated.
Thanks.
