[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext

Hi List

I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes).

I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration.

My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time?

Dovecot version: 1.0.7 (from dovecot-1.0.7-7.el5_7.1 rpm)

The output of dovecot -n is:

# 1.0.7: /etc/dovecot.conf info_log_path: /var/log/dovecot.debug verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~:INBOX=~/Mailbox mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438

My dovecot.conf is as follows:

info_log_path = /var/log/dovecot.debug verbose_ssl = yes mail_location = mbox:~:INBOX=~/Mailbox mail_debug = yes protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster@example.com } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } } dict { } plugin { }

Many thanks in advance! Traiano
