Re: [security-services] Re: Dutch eID Preso follow up. RE: Proposed Minutes for SSTC Call (Nov 25, 2014)
Do you mean specifying the attributes you want back, or actually
"specifying the subject"? The latter is a pretty unusual use case for a
front-channel profile, since the subject is implicitly whoever is sitting
at the client.

Both are required. 

You specify the attributes you want back for the initial authentication at the Identity Provider.  

You should specify the (requested) subject if you want additional attributes from an Attribute Provider. This user previously authenticated at the Identity Provider. For this, they currently envision an attributequery over a front-end channel (because they need user consent per attribute); I understood that your suggestion was to implement this as Web SSO instead.

Thx
