Yes, WIF supports WS-Trust. The docs: http://msdn.microsoft.com/en-us/library/ee748475.aspx
It'd help if you explained the scenario a little bit more. Are you building a website? Are you trying to authenticate users on "PicketLink".
WS-Trust
is generally used for "rich clients" (used for "active federation"). WS-Federation
(and SAML 2.0
) are typically used for web sites (used for "passive federation").
WIF can do WS-Trust
and WS-Federation
. It can't do SAML (the protocol). Confusion is often augmented by the fact that people use the word SAML
to refer both to the protocol and the token format. WS-Federation uses SAML tokens. WIF understands SAML Tokens.
