Freeradius return filter-id group ID
 

We have a FreeIPA as domain controller and we are planing to use Freeradius as authentication for the Wireless, i configured freeradius with LDAP and i can do authentication with a domain user, now the network team asked me to configure freeradius to return a filter-i of the user group assigned ID, example we have user1:

I did some research on google and i found that i have to modify the file /etc/raddb/sites-enabled/default like in the link bellow but not exactly the same configuration i'm looking for: https://stackoverflow.com/questions/...dius-filter-id

Any suggestion please ?

Thanks
