John,

We could do that (pushing back to OpenSIPS all values for that RADIUS AVP), but it may be dangerous if you use on the OpenSIPS side a variable that does not support multiple values - actually the AVPs are the only one doing that.

Imagine the RADIUS reply returns multiple instances on an RADIUS AVP. And you use a $var() variable to get the value - each value will be pushed to that $var(), but as it can hold only one value, it will keep being overwritten -> only last value will be actually available. If this behavior is not a problem, we can fix the code and iterate through the entire list of RADIUS AVP and get all instances.

Bogdan,

I was hoping to get all the values returned in 1 avp, the avp defined for
Cisco-AVPairs in set2. This takes advantage of the ability of OpenSIPS avps
to hold multiple indexed values and also means minimal changes to the
documentation of the aaa_radius module. If you add a numeric index in the
set definition, you must know which position the required attribute is in
and it is even possible the server may return them in a different order.
Also, if you want to retrieve 10 values this makes the set2 definition very
big and clumsy. Adding an index in the set definition would only be a good
solution if the index was a string identifying the Attribute name within
Cisco-AVPairs.

I would be very happy to test if you can show me what changes need to be
made in the sources. I would have tried it already, but wasn't sure how to
add multiple values to the avp.

John,

I understand the issue and agree over the need of a solution. Two possible
approaches:
      - return all the values for that radius AVP
      - include an index in the set definition - to say which instance of the
radius AVP you are looking for

Hi Bogdan,

Yes absolutely certain. I used Wireshark to check.

I did make a little progress with this problem after finding some info
on the Internet.
The name that has to be used in set2 is "Cisco-AVPair". This allows me
to retrieve just one VSA value.
The *real* problem is that you cannot retrieve values 2, 3, 4, etc.
This is because multiple instances are returned using the same VSA.
They are all returned by the server in the attribute called
h323-ivr-in. I even found the code in the sources that retrieves them.
It loops through every instance in
set2 and looks for 1 matching value. So even if you add "Cisco-AVPair"
several times into set2 all you get is the first matching value many
times.

Hi John,

It may be a stupid question, but are you sure the AVP does exist in
the RADIUS reply ?

Hi,

With help from this forum, I have just got radius_send_auth working.
I needed some extra dictionaries including dictionary.cisco In that
dictionary, there are vendor specific attributes like this:
ATTRIBUTE       h323-ivr-in                     100     string
Cisco
ATTRIBUTE       h323-credit-amount              101     string
Cisco

My Radius server returns some data using these VSA's. In particular,
it returns many values using the same VSA - h323-ivr-in

I am having trouble recovering the returned values using set2 of
radius_send_auth Can anyone advise me how I should define set2 to get
at these returned values? I have tried the following with no success:

modparam("aaa_radius", "sets", "set2 =
(h323-return-code=$avp(retcode),
h323-ivr-in=$avp(authretvals))")

After the function is called, there are no values in
$avp(authretvals)

Thanks.
