Ok,thanks Alan

I've read the documentation about rlm_ippool on freeradius wiki and in
particular
http://wiki.freeradious.org/index.php/Ippool_and_radius_clients (I've
not found rlm_ippool documentation in freeradius installed docs).
Now I've specified the NAS-IP-Address and NAS-Identifier in
chillispot, with the same results when I try to login with this user:

prova   Pool-Name:="main_pool", Auth-Type := Local, User-Password == "a"
        Service-Type = Framed-User,
        Fall-Through = no
defined in users file

This is the new output:

rlm_ippool: Searching for an entry for nas/port: 127.0.0.1/1

        NAS-Identifier = "localhost"

        Acct-Session-Id = "44f0825400000001"

When I try to login with LDAP users the debug says that can't find
Pool-Name attribute (but as shown in the first post) Pool-Name
attribute is set in the users file.
What's wrong in the first and in the second cases?

Thanks, Giusy
