dovecot - Mar 2005 - Multiple auth method problem

Hi,

I'm having issues getting the multiple authentication methods of dovecot 
1.0-test65 to work correctly on NetBSD. I am combining a MySQL database 
of virtual host accounts with the system password database of local 
machine accounts. Both work correctly when enabled on their own, but 
when enabled together only the one listed first in the "auth default" 
section of dovecot.conf  works - the other logs the following error 
(line 5 below):

Mar 29 21:56:50 rivendell dovecot: Dovecot v1.0-test65 starting up
Mar 29 21:56:51 rivendell dovecot: auth(default): mysql: Connected to 
127.0.0.1
(maildomains)
Mar 29 21:56:51 rivendell dovecot: auth-worker(default): mysql: 
Connected to 127
.0.0.1 (maildomains)
Mar 29 21:57:05 rivendell dovecot: auth-worker(default): BUG: PASSV had 
invalid
passdb num
Mar 29 21:57:38 rivendell dovecot: Killed with signal 2

To the client, dovecot locks up when a LOGIN command is issued for a 
user which can't be authenticated using the first method available (in 
my case, passwd). So for me, /etc/passwd users can still log in ok, but 
dovecot will lock up whenever a login with any other username is attempted.

My dovecot.conf file is attached - can anyone shed any light on this and 
help me get going?

Cheers,

Timshel

This should fix it:

Thanks very much - I downloaded today's nightly source and it fixes the 
problem. Now I can use both my virtual domains and local users! Very nice!

Faithfully,

Timshel
