i had the pwcheck_method directive in there, along with the path to one of two saslauthd mux's. /var/run/saslauthd/mux and /run/saslauthd/mux, which both show up as "srwxrwxrwx" and are owned by root:root. testing using testsaslauthd works with my id, but i am not sure how to have authentication work when the other process is binding with "cn=user,dc=domain,dc=tld" and not a username.
