SubjectConfirmationData Address & IPv6

[Cantor, Scott]

I know roughly nothing about IPv6 but if the standard is reasonably explicit about what to do then I'm quite comfortable treating it as a bug.

It's odd that the Shibboleth SP doesn't notice this though, so I'd have to look into why. Perhaps the brackets are the norm when reading REMOTE_ADDR anyway. So the problem is that I suspect if we "fix" this it will just break our SP in the bargain without patches there.
