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
