Freeradius Accounting using different virtual server

[Ryan Setiawan H]

Hi,
    I'm using freeradius 2.0.5... many client authenticate againt us 
that is segmented by realm ( / IPASS). the server will strip the 
username realm and proxying  to localhost with different port number ( 
so i create many listen section with point to their own virtual server ) 
ex like this :
realm test1/username --> will go to 127.0.0.1:1912( auth) 127.0.0.1:1913 
(acct) using virtual server link1
realm test2/username --> will go to 127.0.0.1:2012 ( auth) 
127.0.0.1:2013 (acct) using virtual server link2 .. etc
for 127.0.0.1 I'm using per socket client to differentiate each client
the problem rise when I want to differentiate each virtual server 
accounting ( radutmp, radwtmp, and detail file), because using default 
accounting file each realm will be "muddle" into one file. In module 
authorization and authentication I can create many instance ex( ldap1 
ldap2 ldap3), but *not work* at accounting module ex ( detail1 detail2 
detail3 ). is there a way to do this? could someone give some example?

Thank you
Ryan Setiawan H
