hello, An external request must be used on the internal server to transfer Attributes from the internal server to the REST module. Until now, we copied Attributes one by one. example) &Calling-Station-Id = &outer.request:Calling-Station-Id &Called-Station-Id = &outer.request:Called-Station-Id No problem. But now we are in a situation where we have to use all Attributes. So what I tried &request = &outer.request All Attributes were copied, but authentication could not be completed because Attributes that should not have been copied were also copied. (EAP session-related properties) Other than the method just mentioned, there are only two methods that I know of. 1. As in the example, specify all Attributes one by one. 2. Change the copy_request_to_tunnel option of the EAP module to “yes”. Option 1 is the least desirable method. If it becomes necessary to add an attribute, a restart of FreeRADIUS is required. 2. It's the simplest method, but the documentation says "use it only for compatibility reasons." I got the "don't use it" feeling here. I don't know the exact reason, but it's probably for security reasons. Is there a better way you know? Or is there no problem if I just use copy_request_to_tunnel ?
