Fall-Through attribute, reply or configure item?

I'm reading the documentation of freeradius 2.1.3 (I've not gone through it all yet) and I find that "Fall-Through = Yes" is always specified as a reply attribute. But it isn't a real reply attribute isn't it? It's more of a configure attribute like Cleartext-Password, right? So it should be used in a check line with := (or radcheck DB table). I understand that changing this will probably mean to much work for FR administrators, I'm only asking to make things clearer to me. ps. is there a list of the special configure attributes that freeradius works with? -- damjan | дамјан This is my jabber ID --> damjan@bagra.net.mk -- not my mail address, it's a Jabber ID --^ :)
