Hi all, 

I read through the mailing list discussion raised by Nat in this mail to the 
list on the 3rd of December, see 
http://www.ietf.org/mail-archive/web/oauth/current/msg10203.html 

There were two types of issues:

1) The current text about the issuer (in Section 5.1 of 
<draft-ietf-oauth-assertions-08.txt> says that the assertion can either be 
created by the client (in which case it is self-signed) or it can be created by 
some other entity. 

There was, however, the perception that the current text, in the way it is 
worded, creates the impression that third party token services excludes 
entities like the resource owner. 

2) Some folks had the idea that the resource owner could create the assertion 
and they had a specific use case in mind. While this is not a currently 
deployed scenario (using OAuth technology) there seem to be some other 
deployment (the Austrian eID card deployment was mentioned by Nat) that could 
be re-build with this support in mind.

It seemed that just mentioning that the resource owner could create the 
assertion wouldn't be enough to understand the scenario. A more detailed 
writeup of the envisioned scenario would be needed but has not been provided to 
the mailing list. 

To me it seems that the best approach would be to do the following:  

a) to update the text in Section 5.1 as suggested by Nat in his mail 
http://www.ietf.org/mail-archive/web/oauth/current/msg10222.html

This by itself would not lead to any normative text change but may make it 
clear what the intention was. 

b) to encourage those who care about the use case where the resource owner 
creates the assertion to compile a document and to submit it to the group. This 
would allow us to evaluate whether all the required functionality is indeed 
available. 

Ciao
Hannes
