Does your patch also address the problem where, when a user enters a
password wrong once, subsequent attempts in the same smtp/auth
connection fail with:

dovecot_plain authenticator failed for ...: 535 Incorrect authentication data (set_id=...)

and dovecot reports:

dovecot: auth(default): BUG: Authentication client gave a PID 1301 of existing connection
