Home Server for Only Accounting/Coa/Auth

[Geaaru]

Hi,
i'm trying to configure an home_server for only accounting packets:
home_server radius_pyserver1 {
#  type = auth+acct  type = acct
  ipaddr = 127.0.0.1
  port = 18131
  # Radius Backend secret  secret = xxxx
  response_window = 15  zombie_period = 40  ping_interval = 5 
response_timeouts = 3
   status_check = status-server  check_interval = 10 
num_answers_to_alive = 2
  max_outstanding = 65536}
home_server_pool pool_py {  #  The default type is fail-over.  type =
load-balance
  home_server = radius_pyserver1}
but it seems that if I use a value differnt of "auth+acct" (acct, coa
or auth) I receive an error on bootstrap like this:  Unknown
home_server "radius_pyserver1".
With type "auth+acct" all works fine.
I currently use v.3.0.17. Are there some changes on home_server that
doesn't permit use of single type on home_server or is there an issue ?
Thanks in advance.Geaaru
