Authentication failure with postfix and sasl using sasldb

I'm really not sure what my issue is. I've checked several guides, and I am sure I have set this up correctly, including config fails, restarting the service, permissions etc. OS is Ubuntu Server. When testing with testsaslauthd -u myemail@mydomain-p password I only ever get: 0: NO "authentication failed" My postfix.conf (comments deleted): smtpd_sasl_auth_enable = yes smtpd_sasl_type = cyrus smtpd_sasl_path = smtpd smtpd_sasl_local_domain = $mydomain smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no append_dot_mydomain = no readme_directory = no smtpd_use_tls=no smtpd_relay_restrictions = permit_mynetworks defer_unauth_destination myhostname = mydomain alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = $myhostname localhost.$mydomain localhost $mydomain relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.16.0.0/16 mailbox_command = mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all mydomain = mydomain home_mailbox = Maildir/ My smtp.conf for sasl pwcheck_method:auxprop auxprop_plugin: sasldb mech_list: PLAIN LOGIN CRAM-MD5 My saslauthd config: START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="sasldb" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/run/saslauthd" All permissions are correct and I have restarted the services to ensure. mail.warn shows the following: warning: unknown[myip]: SASL LOGIN authentication failed: authentication failure What can I do to troubleshoot?
