Hi Allen,<br><br>Scenario #1 RP uses checkid_immediate with directed identity: the OP uses the last persona the user selected with that RP. This makes sense when the RP is using checkid_immediate to auto-login the user from their last session and just wants to make sure the user is still signed into their OP.<br>
<br>Scenario #2 RP uses checkid_immediate with a claimed identifier the user has logged into the RP previously: OP can tell from the claimed identifier which persona is in use. This assumes personas are tied to identifiers, which they may not be. In the more advanced case (which I am doubtful needs to be supported) of having multiple personas that can be used with an individual identifier (in order to manage which values for attributes to send) it gets harder to give a solid answer.<br>

Hi Andrew -<br>
<br>
How is checkid_immediate supposed to work if a single account on the OP can have multiple OpenIDs on the RP?<br><font color="#888888">

Contrast that to Yahoo supporting multiple personas: I'm logged into all of them at once, so no matter which RP I visit as a Yahoo! customer, Yahoo can implicitly log me into those RPs regardless of which claimed_id and/or persona from Yahoo I used to log in with them.<br>
