Hi Manuel,<br><br>AX has RP to OP push, and OP to RP update, allowing the chain reaction that you describe.<br><br>However, no OP or RP to my knowledge implements this part of the spec. So unless you're planning to own or control all of the sites involved, it's too soon to achieve what you're describing.<br>

Hello,<br>
<br>
Please excuse me if this subject is not appropriate for this list.<br>
<br>
Looking at the available specs I could not figure if a certain feature<br>
that I am interested is supported by any of the OpenID specs or any<br>
extension that is in progress.<br>
<br>
I am working on an implementation on which the OpenID provider not only<br>
can authenticate an account, but also centralizes e-mail addresses and<br>
aother account attributes of all accounts.<br>
<br>
The problem that I need to solve is the need for the consumer sites to<br>
have the account e-mail addresses updated, as those sites send several<br>
types of newsletters specific of the sites.<br>
<br>
So, if an user updates the account e-mail address in one consumer site,<br>
I need a) the e-mail address to be pushed in realtime to the<br>
authentication provider and b) the authentication provider pushes the<br>
updated account e-mail addresses to any other consumers that are using<br>
the same user account without having to wait for the user to login in<br>
those sites.<br>
<br>
It seems that OpenID Attribute Exchange spec handles a) but interaction<br>
needs to depart from consumer sites. So, b) does not seem to be handled<br>
by AX. Am I correct? If that is the case, is there any other spec,<br>
published or being worked on, that handles b), i.e push account<br>
attribute updates from the provider to any relevant consumers?<br>
<br>
