Yes.
To be as precise as I dare: ADFS 2.0 when using passive (WS-Federation 1.2, chapter 13) sends only 1.1 Tokens. There are all kind of historical reasons for that. If you really need 2.x Tokens, then you will have to use a Custom STS. Nothing against
it, but why would you want to (just curious)?
