Can someone help me to understand how SASL works with PAM or verify my understanding? I found the following explanation from http://www.sendmail.org/~ca/email/cyrus/sysadmin.html ... The PAM authentication for SASL only affects the plaintext authentication it does. It has no effect on the other mechanisms, so it is incorrect to try to use PAM to enforce additional restrictions beyond correct password on an application that uses SASL for authentication. ... Does it mean that SASL/PAM only works AUTH=PLAIN? (my understanding: it doesn't work with AUTH=LOGIN) Thank you very much. Arthur Gong
