Dovecot's managesieve server fails to authenticate using the default pam configuration. Reproducible: Always Steps to Reproduce: 1. start dovecot/managesieve. Set it up for plain authentication and no ssl 2. telnet localhost 2000 3. AUTHENTICATE "PLAIN" "<yourbase64user/password>" Actual Results: You always get the reply NO. If you switch on debuging in the managesieve protocol (mail_debug = yes) you see a pam error in the log. Resolution: cd /etc/pam.d ln -s imap managesieve The managesieve protocol needs a pam module named after itself. Now it works!!
Thanks, in CVS (1.1.1-r1).
