[OpenID] OpenID and webmail

[Webtech]

Hi,

when you use OpenID with a webmail who need access to an IMAP server, 
you've a problem : you don't have the user password.
For example, you're logged in a web application WEB1, you open the 
webmail WEB2 without authentication, but the webmail needs user an d 
password for IMAP authentication...

Using CAS, there's a solution with "proxy CAS" and proxy tickets, but I 
haven't found similar solution with OpenID.

Is there someone to help me ?

Thanks.
