How to copy all EAP Request Attributes to internal server?

[남혁준]

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 ?
