This is possible now if you download the latest patches for 4.9. The
patches add functionality for handling Diameter Grouped attributes when
converting from RADIUS reply.

You can continue using the dictionaries in this format. To test, I did
the following:

Specified your additional RADIUS dictionary with system dictionary using
'DictionaryFile'. Specified your additional Diameter dictionary with
'DiameterDictionaryFile'.

Used this file with AuthBy FILE (quotes required):
mikem User-Password=fred
	Location-Information="Line-Identifier=\"ADSL;privaccess-xxx\""

This is the output from reply diapwtst gets (-dictionary option needed too):

  Code:           265 (AA)
  Version:        1
  Flags:          0x0 ()
  Application ID: 1 (Nasreq)
  Hop-to-Hop ID:  1
  End-to-End ID:  2887778305
  Attributes:
    Session-Id: .M., testoriginhost;1234;1
    Origin-Realm: .M., testoriginrealm
    Auth-Application-Id: .M., NASREQ
    Auth-Request-Type: .M., AUTHORIZE_AUTHENTICATE
    Origin-Host: .M., zulu.open.com.au
    Result-Code: .M., DIAMETER_SUCCESS
    Location-Information: V..,
       Line-Identifier: V.., ADSL;privaccess-xxx


There is no need to modify any of the .pm files after patching. The
above can be setup with dictionary files.

Please let us know how it works.

Thanks!
Heikki
