New subject: [Serusers] SER/SIP & RADIUS/Auth-Type = Digest

1 Oct 2003

OK, I figured out that I had messed up the digest file that I was using
with radclient.  I now get a correct response using radclient to test
against the freeradius server.  When I try to auth from ser though, I am
getting a failure.  Group authenticate returns reject.  I'm not
intending to do any group authentication.  I tried loading the
group_radius module instead of the group module and I also tried loading
no group modules, but I still get the same error.

Please see my radiusd-x output...

modcall: group authorize returns ok
  rad_check_password:  Found Auth-Type Digest
auth: type "digest"
modcall: entering group authenticate
A1 = sdolloff:voip2.test.net:test
A2 = REGISTER:sip:voip2.test.net

 It seems that the "User-Password" attribute is missing for user 
"sdolloff" in radius users file. It should look like the example from 
Radius HOW-TO:
http://iptel.org/ser/doc/ser_radius/ser_radius.html#AEN139.

Your RADIUS server has to support Digest Authentication, and the line
above seems to indicate that it does not do that.

If you can change your Radius server software, give Freeradius or
Radiator (commercial, but excellent) a try. If you can not, try to
educate your existing server to do CHAP-Type authentication.

hope that helps.
