Anyway If I may reask a new question about adding multiple attribute to reply on the radius that proxy.
The solution you gave me, (eg use users file and match the Realm Attribute, DEFAULT Realm == whatever) is ok for a "ISP" radius (eg end radius), not for a "Wholesale" radius (eg radius that proxy). According to what I saw in debug, Realm attribute is only use in the request (eg add by the proxy radius), but even if I force it in the reply of the end radius, it won't be consider in the reply by the proxy radius.
So that I can not add the wanted attribute as I would like too.
For now what I do, is use the attrs file for first attribute, then use unlang in post auth to add the second attribute.
Files module supports use of files in post-auth and post-proxy. Add this to raddb/modules/files: postproxy_usersfile = ${confdir}/postproxy_users Then create postproxy_users in raddb directory (where other users files are) and list that DEAFAULT entry there. Ivan Kalik Kalik Informatika ISP
