RE: Comments to "RADIUS Attributes Extension "
Thanks for the quick reply, Farid.
I see the NAS may need to associate the user with some identity. But (using your example) how does a NAS know who is email@example.com ? firstname.lastname@example.org means nothing.
Or is it the case that the NAS will use email@example.com for example to report accounting information to other network element, where the mapping firstname.lastname@example.org<->"real identity" exists ?

Yes. We should.

That is not the problem. The problem is that the NAS needs to associate
the user with some identity when the user authenticates to the access
network using an anonymous id. So, the home network needs to convey
some form of identity to the NAS for that user's session -- it does not
have to be the user's real identity. For example, it could be
firstname.lastname@example.org. Please let me know if this did not answer questions.

We chose a generic name that can used for other purposes. We can use
specific name like billable identity or chargeable user identity.
