Tavis,
Thanks for your input, that did fix the problem. I did have the "files" before "sql" in radiusd.conf. Also I followed your advice about taking out "Auth-Type" out of mysql table and let DEFAULT in users file do the trick.
However it's semi-working.
Accourding to the snippet from my ser.cfg file, now I get the following in stderr: 0(4866) 000d2890-d47f0003-4a230347-53c6189b@yy.yy.yy.yy - sip:1000@xx.xx.xx.xx - User authenticated... 0(4866) Credentials: User is in Radius Group Dialin!!!! 0(4866) Credentials: User is in Radius Group Dialin2!!!!
No matter which parameter I use for the function radius_is_user_in(), it always returns TRUE. When in fact it should return FALSE for Group Dialin2. I've tried:
if (radius_is_user_in("From", "Dialin2")){... if (radius_is_user_in("Credentials", "Dialin2")){...
Here's what I did to fix future problems:
EFAULT Auth-Type = System Fall-Through = 1
DEFAULT Service-Type == Call-Check, Auth-Type := Digest
DEFAULT Service-Type == Group-Check, Auth-Type := None
DEFAULT Service-Type == SIP-Session, Auth-Type := Digest
DEFAULT Service-Type == SIP-Callee-AVPs, Auth-Type := None
DEFAULT Service-Type == SIP-Caller-AVPs, Auth-Type := None
Also, for those of you using the latest version of freeradius, you may have to comment out the following lines as they conflict with dictionary.ser (SER CVS) and dictionary.sip (comes with radiusclient-NG)
#VALUE Service-Type Voice 12 #VALUE Service-Type Fax 13 #VALUE Service-Type Modem-Relay 14 #VALUE Service-Type IAPP-Register 15 #VALUE Service-Type IAPP-AP-Check 16
Thanks,
Lenir

Oops, i spoke too soon
It looks like you have placed the "files" module before the "sql" module in your radiusd.conf
Its matching your DEFAULT entry in files (setting the Auth-Type to none) but the sql module is later changing the Auth-Type to "digest"
Changing the order would solve this problem, as you want it to match the SQL statement first and than the section in the files last (which changes the Auth-Type)
Also, you may want to reduce the load on your database by not setting the Auth-Type in the database and instead setting in the users file with a DEFAULT statement as (at least in my case) it isn't somthing that need to be dynamic.

Hello list,
I've been trying my hardest today to get group_radius to work, and its function radius_is_user_in(). I'm running ser0.9.4 and freeradius 1.0.4 with the mysql backend and digest authentication.
Radius authentication works fine. The problem is that when radius_is_user_in() function gets called, it sends a radius message but without the User-Password field and freeradius complains that it requires it since we are using Digest. I've seen a couple of posts here, but they were never answered: http://mail.iptel.org/pipermail/serusers/2005-March/017342.html http://mail.iptel.org/pipermail/serusers/2005-March/017075.html
I have a small test in my ser.cfg file: if (!radius_www_authorize("")) { xlog("L_I","%ci - %fu - User not authenticated, Radius Authenticating...\n"); www_challenge("","0"); break; } else { xlog("L_I","%ci - %fu - User authenticated...\n"); };
if (radius_is_user_in("From", "Dialin")){ xlog("L_I","From: User is in Radius Group Dialin!!!!\n"); } else { xlog("L_I","From: User *IS NOT* Group Dialin!!!!!\n"); }; if (radius_is_user_in("Credentials", "Dialin2")){ xlog("L_I","From: User is in Radius Group Dialin2!!!!\n"); } else { xlog("L_I","From: User *IS NOT* Group Dialin2!!!!!\n"); };
In /etc/raddb/users file I have the following at line 152: DEFAULT Auth-Type = System Fall-Through = 1
DEFAULT Service-Type == Group-Check, Auth-Type := None
DEFAULT Service-Type == SIP-Callee-AVPs, Auth-Type := None
These are mysql tables:

This is the debug I get from freeradius for the group check:

Any help in this matter would be deeply appreciated,
