Sending Cisco AV Pairs per realm

Hi I have a number of realms on my radius server (FreeRADIUS Version 1.1.6). All users are valid in both realms (one is for dialup, one for broadband). e.g. dang@dsl.realm dang@dial.realm All realm's are stripped so that the user (dang in the examples above) is authenticated. However, on dial.realm I need to return a couple of Cisco-Avpair attributes; how can this be done? I have tried a hints file, however although I get the message on debug: hints: Matched DEFAULT at 17 The data specifies is not sent back in the RADIUS reply. Any help would be greatly appreciated! Cheers Dan
