I cannot wrap my mind around saslauthd and auxprop. Does auxprop use the sasldb file to authenticate users that have been added using the 'saslpasswd2' command? What is saslauthd trying to use for authentication, would it be the mechs shown in a 'saslauthd -v' output? What does changing the value in the Sendmail.conf file from saslauthd to auxprop or vice versa doing? Running a ps I see that saslauthd is using the shadow mech: /usr/sbin/saslauthd -m /var/run/saslauthd -a shadow But I have no users in the shadow file other than cyrus and my users for my mail server are in the sasldb file? I have read the documentation on the cyrus site, the man pages and searched the mailing list but I still cannot grasp what seems to be a simple concept. Can someone shed some light or at least point me in the right direction? Jon ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
