1.0alpha2, Debian, using PAM and I get this error:

Sep 15 21:07:11 localhost dovecot: chdir(/dev/null) failed with uid 42:
Not a directory  21:28:14

Anyway I don't like this so much.

Maybe using PAM is a cleaner solution:

/etc/pam.d/dovecot:
    ...
    auth required pam_listfile.so onerr=succeed item=user sense=deny \
     file=/etc/dovecot.noauth
    ...

/etc/dovecot.noauth:
luser1
luser2
...
