Should I be able to either.... 1) Set a Huntgroup via the huntgroups file (matching on NAS-IP-Address) and use that in the Hints file as a match (Huntgroup-Name == "blah") or 2) Set a Hint in the hints file and use that to define as the match for the Huntgroup Currently testing on FreeRADIUS Version 1.1.0 and the files seem to be parsed independently so attributes modified/added in one aren't visible in the other ? Essentially I'd like to set both a huntgroup and perform some username substitution in hints on queries from the same set of NAS. I can define the full set of NAS in both files of course but was hoping to only define the list of NAS-IP-Address once. Ideally set the Huntgroup first and then use the Huntgroup-Name in the Hints file. Thanks Dean Smith
