sasl_pwcheck_method: auxprop

and see if that works.

Also, since your Postfix works, try duplicating its config in 

sasl_saslauthd_version: 2
sasl_pwcheck_method: saslauthd
sasl_mech_list: plain login cram-md5 digest-md5

You'll also need:

sasl_saslauthd_path: /var/spool/postfix/var/run/saslauthd/mux

and remove:

sasl_auto_transition: no

Make sure the cyrus user has permissions to access the mux:

sudo -u cyrus ls /var/spool/postfix/var/run/saslauthd/mux
