Sorry, i always tend to think more than i write/talk
What i meant was that you can pass the necessary information during the authentication using the auth_radius module or during feature request using the avp_radius depending on what you are trying to do with the feature

I will try that as a workaround.
For the SER-DEVEL and OPENSER-DEVEL guys...can any of you comment on this?
Thanks

I've never used the group_radius module so i'm not certain what it expects from the radius server (its not well documented currently)
Although you may be able to optimize a bit and skip the radius_is_user_in function call and simply pass the users group back as an SIP-AVP attribute in the radreply table, and then check for that AVP in the OpenSER script
What i've done is commented the group checking SQL from the freeradius sql.conf file so that when a user authenticates or when an avp_radius call is made only 2 SQL queries are sent, instead of the 4-5 used when group check is enabled.
Try this, it should work and it will save you ~10 sql queries and a radius request/response

Well either way the radius server is going to respond with an "Access-Accept" because you have set the auth-type to "none" (which is necessary because you are not authenticating and can not provide the necessary credentials).
From the trace you showed me below, i see two radius requests both for
the user 1000 and both of which respond as i would expect.
I'm not what you are trying to accomplish, are you using the group_radius module or just loading the group information using avp_radius?

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

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

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
