RE: [saml-dev] Confusion regarding AuthnContext
If your IdP only supports PasswordProtectedTransport and the SP
requests something different, the request should fail.  You should not return a
successful response that doesn’t meet the requirements of the request.

"Configured on the SP side" meant that
administrator could configure the AuthnContextClassRef (in our case
PasswordProtectedTransport) on the SP side like some SP's allow (e.g. WebEx)

 

Our target are SaaS applications like salesforce and
googleapps (which *do* not place any such restriction on AuthnContextClassRef)
but wanted to be doubly sure before implementing an IdP which would always send
'PasswordProtectedTransport'.

 

What about government applications? Any idea whether they
allow it to be configurable.

 

Thanks once again.

I don't know what you mean by
"configure on the SP side". You can configure

an SP to ask for something specific, but you can't just set what the

resulting context is/was on the SP end.

If you're asking whether there are SPs that require particular classes,

sure, I suppose. What's your audience of SPs? There aren't generally just

"SPs in the wild" outside of a particular business context.
