Some >hints about where to go hunting would be most appreciated. What is your sasl configuration in imapd.conf? (grep for sasl) If pwcheck_method does not include 'auxprop' in your configuration, then you are not using sasldb2 to authenticate. Your admin accounts should be using the same authentication database as your normal users, which could be PAM, for instance, if you're configured to use saslauthd. Also, be aware that the 'A01 AUTHENTICATE PLAIN ...' strings you included in your original email contain the uuencoded form of your password, and can be trivially reversed. If your server is publicly accessible, you may want to change your admin passwords. -- Dan White ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
