Thank you for both answers, I'm now trying with preproxy_users and with 
variable substitution.
But I still can't get it to work.

I read the following packet in the pre-proxy log on the proxier
# cat 
/var/log/radius/radacct/127.0.0.1/pre-proxy-detail-20050806 
Packet-Type = Access-Request
Sat Aug  6 15:23:17 2005
        User-Name = "matteo.faleschini"
        NAS-IP-Address = 127.0.0.1
        Client-IP-Address = 127.0.0.1
        Realm = "encrypt"
        Proxy-State = 0x3432

So I tried both line (not together) on the preproxy_users file (the first could have an error inside)

DEFAULT Realm == encrypt
        User-Name := `%{User-Name}@students`

DEFAULT User-Name =~ "\\."
        User-Name := "user.modified"

But on the other radius server I always get this log

Packet-Type = Access-Request
Sat Aug  6 15:20:17 2005
        User-Name = "matteo.faleschini"
        NAS-IP-Address = 127.0.0.1
        Proxy-State = 0x3432
        Client-IP-Address = 192.168.1.2

My radiusd.conf file only includes these lines for pre-proxying

pre-proxy {
#       attr_rewrite

        #  If you want to have a log of packets proxied to a home
        #  server, un-comment the following line, and the
        #  'detail pre_proxy_log' section, above.
        pre_proxy_log
}

I'm I still missing something? like a directive related to the use of the 
preproxy_users file?
Thank you,
