saslauthd, with default compile options, does not contain support for
sasldb. It is recommended to use the sasldb auxprop plugin in this scenario
rather than saslauthd. Configure /etc/imapd.conf with:

sasl_auxprop_plugin: sasldb
sasl_pwcheck_method: auxprop

Configure your postfix smtpd.conf with:

auxprop_plugin: sasldb
pwcheck_method: auxprop

The sasldb database is typically contained in /etc, and not underneath
underneath the Postfix chroot. Either disable chrooting of smtpd in
/etc/postfix/master.cf, or configure an appropriate 'sasl_sasldb_path' in
/etc/imapd.conf, and a 'sasldb_path' in your postfix smtpd.conf file. If
you continue to chroot postfix, you will also need to specify the location
of the sasldb database with 'saslpasswd2 -f <path>'.

With saslauthd, you may wish to experiment with the '-r' option
(/etc/default/saslauthd OPTIONS).
