No, it shows just that: "Auth process died too early - shutting down".

Patch, make, replace the dovecot-auth executable, start inetd, telnet 
localhost: just the same error ("EOF while reading..."). The error log 
shows:

dovecot: Jun 21 15:51:53 Error: child 9904 (auth) returned error 53
dovecot: Jun 21 15:51:53 Fatal: Auth process died too early - shutting down

I can't seem to find the new log statements anywhere. They appear only 
if I start dovecot-auth directly, ant it fails like this:

Info: starting dovecot-auth
dovecot-auth: Fatal: MECHANISMS environment is unset

If it helps, echoing its return value (echo $?) gives 89.
