I'm seeing the same behavior under Debian Sid. (First time I've tried it,
so I don't know whether the problem is connected to a particular update.)

I can make an imap connection using passwd-file authentication. When I
switch to mysql, the mysql log shows a connection when dovecot starts but
no further activity. The reply to the imap client is
  NO Temporary authentication failure.

In the mail.log, I see:

Jun 16 06:25:57 server dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Ilip=192.168.1.2^Irip=192.168.1.3^Iresp=AGd1ZXN0QHNhZHQuY29tAGZvbw==
Jun 16 06:25:57 server dovecot: child 4951 (auth-worker) killed with signal 11
Jun 16 06:25:57 server dovecot: auth(default): client out: FAIL^I1^Iuser=foo at sample.com^Itemp
Jun 16 06:25:57 server dovecot: imap-login: Aborted login: user=<foo at sample.com>, method=PLAIN, rip=192.168.1.2, lip=192.168.1.3

Any clues?
