AW: Devices in more than one huntgroup

Hi,

In this thread i found a hint for my config:

http://freeradius.1045715.n5.nabble.com/huntgroups-question-td2756193.html

"The huntgroups are a bit of a hack for backwards compatibility going
back almost a decade. For 2000 machines, I would suggest using
rlm_passwd. See the "man rlm_passwd" page for an example of setting up
groups based on User-Name. The same method can be used to set up groups
based on Client-IP-Address. You then have groups controlled by a flat
text file, which is pretty easy to manage."

passwd groups_local {
        filename = /etc/raddb/groups_local
        format = "~My-Device-Group:*NAS-IP-Address"
        hashsize = 50
        ignorenislike = no
        allowmultiplekeys = no
        delimiter = ":"
}

Groups_local:
readonly:127.0.0.1

Groups_local is called in section "authorize" just after "preprocess".

I always got "returs notfound". If i add User-Name to the config, it´s working.
But i didn´t want to check the username, i just want to add an other flag (My-Device-Group)
additional to huntgroups.

So, how should it work?

Thanks!

Jan
