I just tried to login using my self-issued informationcard
at Fabrikam Friends. But it throws an error page at me.
My guess is that Fabrikam Friends can only handle bearer tokens not holder-of-key tokens. I noticed the same behaviour at the jinformationcard demo shop.
The internal STS in Windows CardSpace issues bearer tokens
while the Firefox ID selector issues holder-of-key tokens.
Kim's Identityblog is still accepting my tokens. Good.
Though I won't rule out that something is wrong with the Firefox id selector tokens. When 's the next interop?
