Re: [OpenID] PAPE yahoo?

Is the yahoo limitation due to the technical nature of openid

Is it due to the open nature of the openid uci model?

Is the advice the same as given to folks who use alternative apis?

Should I tak it as given that a yahoo openid is not appropriate for concluding a $1 credit card transaction?
Even over verisign ssl?

Hi James,

Yahoo supports the PAPE extension specifically to mark our assertions with NIST Auth Level 0, to indicate
that Relying Parties should not Yahoo OpenID assertions to authorize transactions of financial value,
or other high value transactions. We have this documented in our FAQ here:

http://developer.yahoo.com/openid/faq.html

Thanks,
Allen

Hello all,

I have a quick question that doesn't seem to be covered in the existing
spec docs.

If a user enters 'yahoo.com' the OpenID discovery phase yields this xrds
document:

<XRD>
    <Service priority="0">
      <Type>http://specs.openid.net/auth/2.0/server</Type>
      <Type>http://specs.openid.net/extensions/pape/1.0</Type>
      <URI>https://open.login.yahooapis.com/openid/op/auth</URI>
    </Service>
</XRD>

Is a Relying Party to take this as meaning that the Yahoo OpenID server
supports all PAPE policies?

It depends on what you mean by "supports all PAPE policies"?

The XRD above simply says that the Yahoo OpenID 2.0 server supports PAPE,
which means the RP can include a PAPE request in their OpenID 2.0
authentication request to the Yahoo OP, and Yahoo will answer the request
saying which policies it did/didn't use for authentication (e.g., was it
phishing-proof or not?)

It doesn't mean that Yahoo has to support all the potential authentication
policies that the PAPE vocabulary includes.
