"+=" allowed in attrs ??

23 Aug 2012

      Hi

I have set up a virtual server with

 authenticate {
                Auth-Type MS-CHAP {
                        update control {
                                Proxy-To-Realm := "emea_radius_servers"
                        }
                }
        }
        post-auth {
                attr_filter.boa-NX-fwruleuser
        }
}

and the attr.filter looks like

# Joachim Brauer
"blah@blah.de"
   cisco-avpair := "ip:inacl#0=permit ip any 10.1.0.0 255.255.255.224",
   cisco-avpair += "ip:inacl#1=permit ip any 10.2.0.0 255.255.255.224",
   cisco-avpair += "ip:inacl#2=deny ip any any"

However when debugging I see that the 1st cisco-avpair line is processed 
and sent to the NAS and the following 2 lines are NOT sent by freeradius
My question now: is += not allowed in attrs ? or am I doing s.th. wrong 
here ?
Purpose is to enrich the RADIUS response with per user cisco-avpair 
values....
freeradius version is 2.1.12 on RHEL 6.

Thanks for any help.
