Logout SAML Error message v3

[Cantor, Scott]

Your "bug" is that you're trying to use client-side session storage with logout, which is impossible at present. That only changes if we manage to hack something together with DOM storage as a back-end, cookies will never work. Setting the other properties doesn’t affect storage implementations that don't support them.

> NameIdentifier in message

That's an unfortunate message that doesn't matter for logout requests, the subject doesn't get "decoded" on logouts, the NameID just gets used directly.
