[Users] uri_radius and radius_does_user_exist() not working

[Toni Heinonen]

Hi,

I've been through the OpenSER + RADIUS configuration tutorial many,
many times, and it works like a charm, except for the uri_radius
module which I can't get to detect user existence with the
radius_does_user_exist() function.

I'm trying to decide whether to send a 404 or a 480, as such:

if (!lookup("location")) {
  if(radius_does_uri_exist()) {
    sl_send_reply("480", "User offline");
  } else {
    sl_send_reply("404", "User not found");
  };
};

It worked identically with the uri_db module's does_user_exist()
function. Now the RADIUS server doesn't seem to understand the
Call-Check request. I have a dump here:

Can anyone guess why OpenSER always gives a 404 even for users that
exist, but that are simply offline? The users are currently
hand-configured into freeradius's text configuration file users.conf.

PS. What have you found to be the best way to authenticate users from
a domain?  FreeRADIUS using Kerberos 5, LDAP or relaying to a
Microsoft RADIUS (IAS) server?
