eap Mailing List: Re: Questions for draft-barany-eap-gee-01

[Lakshminath Dondeti (ldondeti]

I still don't understand how what you write below is relevant to the 
discussion at hand, but anyway, I think I made my point.

I will note that the word "service" seems to throw people off into 
debates on authentication vs. authorization and that may be what's 
happening here.  If it helps, perhaps the use of the terms L2 access 
and L3 access might be better.

Further, multiple parallel authentications could also be for device 
and user authentications as Kuntal points out.  Other use cases are 
also possible.

regards,
Lakshminath
