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; +----+-----------------------+--------------+-------------+----+ | id | UserName | Attribute | Value | op | +----+-----------------------+--------------+-------------+----+ | 18 | 81000(a)sage.home.local | Service-Type | Group-Check | := | +----+-----------------------+--------------+-------------+----+ 1 row in set (0.00 sec) mysql> SELECT id,UserName,Attribute,Value,op FROM radcheck WHERE Username = '81000(a)sage.home.local' ORDER BY id; +----+-----------------------+---------------+------------------------------ ------+----+ | id | UserName | Attribute | Value | op | +----+-----------------------+---------------+------------------------------ ------+----+ | 23 | 81000(a)sage.home.local | User-Password | $1$d7XAeahG$9f17cb8JaKj8R1z9GpwG4/ | := | | 25 | 81000(a)sage.home.local | Sip-Rpid | 81000 | = | | 30 | 81000(a)sage.home.local | Auth-Type | Digest | := | +----+-----------------------+---------------+------------------------------ ------+----+ mysql> SELECT radgroupcheck.id,radgroupcheck.GroupName,radgroupcheck.Attribute,radgroupche ck.Value,radgroupcheck.op FR OM radgroupcheck,usergroup WHERE usergroup.Username = '81000(a)sage.home.local' AND usergroup.GroupName = radgroupcheck.G roupName ORDER BY radgroupcheck.id; +----+-----------+-----------+--------+----+ | id | GroupName | Attribute | Value | op | +----+-----------+-----------+--------+----+ | 12 | voicemail | Auth-Type | Accept | := | +----+-----------+-----------+--------+----+ Has anyone had a chance to do something like this with success? I am stuck at the moment - any help is greatly appreciated. Thanks. /Vel
