IdP assisting user to present previous identifier

[Dick Hardt]

I expect I will have a number of OpenIDs, as well as lots of directed  
identities. I would like my IdP to keep track of which identity I use  
at what RP. I may forget which public identifier I used at a site,  
and type in the wrong one, and end up creating a new account and be  
confused. I may have used a directed identity, and forget and type in  
a public one, and then once again be creating a new account and be  
confused.

I would like my IdP to be able to suggest which identifier I want to  
be in situations where I am using a different one from what I used in  
the past. This means that the following from:

IdP Rules for Identifier Parameters

1. IdP MUST ALWAYS return the value of openid.identity sent by RP.


would need to be changed so that the IdP can send a different  
identifier then what was sent by the RP.
