Is this maybe dependent on the userdb? Which ones need it? And if I want to use postfix SMTP auth, should I define a second listener, or just re-configure that default one to postfix's needs?

Sorry for the noise, found it commented in the example configuration - it's configured in auth_socket_path. I didn't have a dovecot installation handy, so I only looked online. For dovecot 1.x, the wiki contains the full configuration file with all comments. Couldn't anything like that be done for 2.x as well (even though it's more complicated)?
