Sending Accounting Response

[Padam J Singh]

Hello Alan,

>From the RFC 2866:

4.2.  Accounting-Response

    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

   |                                                               |
   |                                                               |

   |  Attributes ...
   +-+-+-+-+-+-+-+-+-+-+-+-+-

The RFC doesn't categorically say that an accounting response packet SHOULD NOT have attributes.

The NAS is an application I have written - so I will be able to parse attributes in an accounting response.

If the standard postgres module cannot be used to send back attributes in an accounting-response packet, 
can I do the same using any other module like JRadius? I have gone through the rlm_jradius source code, 
and it looks like it doesn't differentiate between accounting and authorization responses when reading value pairs.

Thanks,
Padam
