I installed Postfix, Dovecot, Roundcube, Postfixadmin on Amazon EC2 Linux.
I configured Postfix, Dovecot, Roundcube and Postfixadmin one-by-one, and I can create new mailbox via Postfixadmin. However, I cannot login the newly created mailbox via Roundcube. The Roundcube log shows:
IMAP Error: Login failed for info@domain.com from 11.22.33.44. AUTHENTICATE PLAIN: Authentication failed. in /var/www/html/roundcube/program/lib/Roundcube/rcube_imap.php on line 193 (POST /roundcube/?_task=login&_action=login)
And for the /var/log/maillog, it shows:
ip-172-31-13-226 dovecot: imap-login: Disconnected (auth failed, 1 attempts in 4 secs): user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=
The Dovecot Config is changed as follow ( /etc/dovecot/dovecot.conf ) :
protocols = imap lmtp
dict {
}
!include conf.d/*.conf
!include_try local.conf
And for conf.d/10-mail.conf :
mail_location = maildir:~/Maildir
namespace inbox {
}
mbox_write_locks = fcntl
And for conf.d/10-master.conf :
service imap-login {
inet_listener imap {
}
inet_listener imaps {
}
}
service pop3-login {
inet_listener pop3 {
}
inet_listener pop3s {
}
}
service lmtp {
unix_listener lmtp {
}
}
service imap {
}
service pop3 {
}
service auth {
unix_listener auth-userdb {
user = postfix
group = postfix
}
}
service auth-worker {
}
service dict {
unix_listener dict {
}
}
for conf.d/10-auth.conf :
disable_plaintext_auth = no
!include auth-system.conf.ext
Last, for conf.d/auth-system.conf.ext :
passdb {
driver = pam
}
userdb {
driver = passwd
}
So, what did I config wrong that leads to login failure?
After enabling auth_debug = yes and auth_verbose = yes, here is the log shown in /var/log/maillog:

"Unknown User" error occurred. Seems Dovecot / Roundcube are not reading the same user database. How can I make sure they read the same user database?
