Subject: RE: [ws-sx] Issue 31: Token properties
Each relying party that is protecting a resource based on the token it receives in a WSS Security header will have some policy about what that token needs to say. While WSS can be neutral to that, I don't see how the STS can be... otherwise, how will a WSC be able to get a satisfactory token from the STS?
Are you saying that it's sufficient for a WSP to state that it requires SAML tokens, and that ANY SAML token will do?

Greg,
It's enough for WS-Security, WS-Trust, etc to say I want a SAML token as
that is all the is profiled in WSS, there is nothing that the wire format
of these specifications depend on in regards to token specifics.

Re: [ws-sx] Issue 31: Token
properties
It seems to me that an RST needs to specify the desired properties of the
requested token in enough detail that the STS can satisfy the request
without relying on out-of-band information.
As has already been pointed out, it's not enough to say that you want a
SAML token.

Symon,
The key part of what you quote is "conditions and restrictions on the
wire formats defined by OASIS Web
Services Security [1], WS-SecureConversation [2] and WS-Trust [3] to
a
specific set of typed message interchanges." well Services Security,
WS-SecureConversation and WS-Trust don't depend on any formats of the
tokens for wire formats, applications may but these specifications
don't.

The following is from the charter for our WS-SX TC:
"WS-SecurityPolicy [4] uses the facilities of WS-Policy [5] to
express
the conditions and restrictions on the wire formats defined by OASIS
Web
Services Security [1], WS-SecureConversation [2] and WS-Trust [3] to
a
specific set of typed message interchanges."
From this statement, there is no reason to define the WSS token
properties somewhere else. WS-SecurityPolicy has to define properties
of
token in the WS-Security spec.
For example, Username Token with/without nonce or created tags should
be
definable in the security policy, so that the Policy Enforcement
Point
can enforce the policy accordingly.

That applies to SAML as well, i.e. SubjectConfirmation. It's
meaningless
to
just say "SAML token".
I would say there should be token profiles of many of these specs, if
not
here, fine, but somewhere.
