Re: Final call for consensus poll for IANA #409959 NAS-Port-Type value request

The requests were generated by a pam_radius_auth module, which sends
Service-Type = Authenticate-Only.

That module doesn't even send VSA's, so I had to trick like "if the
sending client was IP adress x.y.z.a, add RESTENA-Service-Type = IMAP
prior to further processing". And there I was lucky that this IP address
has only *one* process that uses RADIUS. Well, standard ugly hacks.

That's true (and that's why I just took a VSA and went my merry way). Of
course, having an IETF-allocated string attribute of sorts
"Extended-Service-Type-Info" that people could fill with whatever is
needed inside their AAA infrastructure would be not so bad. Better than
cluttering Service-Type with hundreds(?) of possible RADIUS-speaking
applications IMHO; where the list would be necessarily incomplete.
