Hi
I have a problem whereby Dovecot 1.0.7 is reporting that a recently setup
virtual user in /etc/dovecot_passdb is 'unknown'. I have been trying to
setup the user 'info' in a plaintext passwd-file /etc/dovecot_passdb as
a
virtual user, ie non system user. I suspect I have not properly setup
'info' as a virtual imap user... if so, how should I do this?
Existing system users are in '/etc/passdb' and authenticate without
problems. System users have their home directory in
/home/system_user1/mail/.imap eg
/home/system_user1/mail/.imap/INBOX ...file is /var/spool/mail/systemuser1
/home/system_user1/mail/.imap/Sent ... file is in
/home/system_user1/mail/Sent
/home/system_user1/mail/.imap/Drafts... file is in
/home/system_user1/mail/Drafts
whereas the postfix virtual user's (username is 'info') mailbox is
configured as... call it /var/spool/mail/virtualusersdomain1/info
Postfix's virtual_mailbox_base = /var/spool/mail. The
virtual_mailbox_domains, including that of user 'info', are a
subdirectory
of /var/spool/mail
This is the log entry produced when user 'info' attempts to login via
squirrelmail:
PLAIN service=IMAP secured lip=::ffff:127.0.0.1
rip=::ffff:127.0.0.1 resp=<hidden>

dovecot: Mar 12 00:32:40 Info: auth(default): pam(info,::ffff:127.0.0.1):

dovecot: Mar 12 00:32:40 Info: auth(default): new auth connection: pid=569
dovecot: Mar 12 00:32:42 Info: auth(default): pam(info,::ffff:127.0.0.1):

dovecot: Mar 12 00:32:42 Info: imap-login: Aborted login: user=<info>,

dovecot: Mar 12 00:32:42 Info: auth(default): client out: FAIL 1
user=info
So, /etc/dovecot_passdb has ownership root:root, permissions 644 and only
the contents:
info:{PLAIN}Myplaintextpassword
I have tried logging in both as info and also as info at virtualusersdomain1
dovecot -n shows:

userdb:
driver: passwd-file
args: home=/var/spool/mail/%d/%n mail=mbox:~/mail /etc/dovecot_passdb
userdb:
driver: passwd
args: /etc/passwd
This is all that was in orginally in /etc/dovecot.conf:
protocols = imap imaps pop3 pop3s
disable_plaintext_auth = no
protocol imap {
}
protocol pop3 {
}
protocol lda {
}
auth default {
mechanisms = plain
}
passdb pam {
}
userdb passwd {
}
user = root
dict {
}
Dovecot runs as root.
Anyway, any advice would be great!
Thanks
