It doesn't support scope ID's. The upcall doesn't send the scopeid if
there's one defined.
Given that we rely on name resolution to some degree with krb5 auth,
I'm not sure that it makes much sense to deal with scopeid's here. AAAA
records in DNS don't have space for them.
PS: I'll fix the getnameinfo() autoconf patch to do what you suggest...
