There isn't really any standard way to do this, unless you count setting up a master password login from your webmail. Several systems have implemented their own SSO auth mechanisms that pass the token to Dovecot, which then verifies it from some external server. I was thinking about creating some semi-standard for that, but not implemented yet. And in any case it would still require some way of verifying the token from all kinds of different SSO servers, so it's not some quick task and I'm not sure if it should be something that would be even distributed with Dovecot.
