returning user and primary group (or any other ldap attribute) with radius response

[Thomas Schweikle]

Hi!

After searching for long with google, or in the manuals, i was not
able to find any cookbook recipe to advice freeradius to respond with
username and primary group for an authenticated user.

The access-point needs this to sort out users into guest or internal
networks. So how can I set up freeradius to return username and
primary group (or any other ldap attribute) with the OK-response?
