Hi, i have read a couple of msg on this list about the same problem i actualy have but could not really find a nice solution for it. I have a case where I use Freeradius for proxy auth/acct to home servers. Lets assume I will be more then 20-40 different realms. Before the answer goes back to the Nas I need to add some attributes and now looking for the best way of doing this. In the past with Cistron or today with the switch in proxy.conf it is easy. I think this is maybe not the right way of doing it parsing the users files and everything else in authentication section twice. My Setup NAS ----- 1 -------> PROXY ------ 2 ---------> Home Radius <---- 4 -------- <----- 3 --------- So in 4 there should be e.g. different DNS servers for each realm. What is your view on this ? What's the best way doing this. Don't know if there is a way to add those Attributes to the Request Reply) attributes so that there still there when the Home Radius sends an answer ? Of course in a scalable way 20-40 realms. I´am already that far that I thought I need to patch the files module to have function for post-proxy which then I could use to parse another users file adding those Attributes Because that was easy Just defaults for each Realm and then adding them. BTW I found some parameter in the modules which do read the realm/proxy stuff which seams to be not used somewhere. It is trusted and hints. Or do you just allow them to be compatible with Cistron. ?? Bye Holger
