On an Ubuntu Server 12.04 system with Dovecot 2.0.19 I am having some trouble with the Dovecot passwords. I am finding this in the logs when I unsuccessfully try to log in:
Jul 07 08:13:25 auth-worker: Debug: pam(user@someDomain.com,212. 179.241.14): lookup service=dovecot Jul 07 08:13:25 auth-worker: Debug: pam(user@someDomain.com,212.179.241.14): #1/1 style=1 msg=Password: Jul 07 08:13:27 auth-worker: Info: pam(user@someDomain.com,212.179.241.14): pam_authenticate() failed: Authentication failure (password mismatch?) (given password: 12345) Jul 07 08:13:29 auth: Debug: client out: FAIL 2 user=user@someDomain.com Jul 07 08:13:29 pop3-login: Info: Disconnected (auth failed, 2 attempts): user=user@someDomain.com, method=PLAIN, rip=212.179.241.14, lip=10.138.11.251
This is not the real password, but an example to show that I think that there is an issue: $ /usr/bin/doveadm pw -u user@someDomain.com -s DIGEST-MD5 Enter new password: # Here I have typed "12345" Retype new password: # Here I have typed "12345" {DIGEST-MD5}f4e442b0dec5009eaa8b9b4104923edc $ printf "12345" | md5sum 827ccb0eea8a706c4c34a16891f84e7b - $
Shouldn't that password match the md5sum check? Also, might I have the file formats wrong? $ cat passwd user@someDomain.com::5000:5000::/var/mail/vhosts/someDomain.com/user $ cat shadow user@someDomain.com:{DIGEST-MD5}f4e442b0dec5009eaa8b9b4104923edc $
Note that testing in Telnet fails the password as well, both when specifying the user without a domain and with a domain:
$ telnet mail.someDomain.com 143 Trying x.x.x.x... Connected to mail.someDomain.com. Escape character is '^]'.
- OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login user 12345 a NO [AUTHENTICATIONFAILED] Authentication failed. e logout
- BYE Logging out e OK Logout completed. Connection closed by foreign host. $ telnet mail.someDomain.com 143 Trying x.x.x.x... Connected to mail.someDomain.com. Escape character is '^]'.

Thanks!
