Password database extra fields and SQL
by Dave 29 Apr '16

29 Apr '16

Hi everyone, first post to the list, be gentle with me! Perhaps I'm missing something here, but it appears to me that many password database extra fields currently aren't much use inside SQL queries? All boolean fields like nologin/nodelay/nopassword are set if the column is present in the returned query, regardless of value (including NULL) For example, say you have a query like: password_query = SELECT hash AS password, NULLIF(active = 1, 'y') AS nologin FROM users WHERE name = '%u' Then nologin will always be set for this account, there's no realistic way to toggle the flag. Has anyone come across any workarounds for this problem that don't sacrifice efficiency by performing multiple lookups? I was considering what would happen if dovecot treated NULL fields as not present, but that immediately conflicts with advice to set password to NULL to satisfy the field requirement on nopassword. Any thoughts? -- Dave

I dimly remember some Windows clients preferring either "LOGIN" or "PLAIN" style mechanism. Have you tried allowing "LOGIN" style authentication? auth_mechanisms = plain login Joseph Tam <jtam.home(a)gmail.com>

Doveadm Replicator problem with PAM passdb
by Adam Joesbury 28 Apr '16

28 Apr '16

Hi Everyone, We are running two CentOS 7.2 servers with Sendmail 8.14.7 V10 and Dovecot 2.2.10 installed on both and are trying to configure Master-Master Replication using doveadm replicator. We are using system users with PAM authentication but are receiving the following fatal error when dsync tries to run: doveadm(user): Fatal: /var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set). Please could someone confirm whether it is possible to configure replication using PAM passdb as the above error seems to suggest it isn't but we have come across various people online who seem to have it working. I don't know whether we need to create a master user or whether we need to create a separate password file with a directory of all of our user's passwords? We do have all the user passwords as they are only internal accounts that we are servicing. Thanks in advance Output of dovecot -n: # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-327.13.1.el7.x86_64 x86_64 CentOS Linux release 7.2.1511 (Core) auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb doveadm_password = secret doveadm_port = 12345 login_greeting = POP3-IMAP server ready. mail_location = maildir:~/Maildir mail_plugins = " notify replication" mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox "Deleted Items" { auto = subscribe special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox "Junk E-mail" { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } prefix = } passdb { args = session=yes setcred=yes failure_show_msg=yes dovecot driver = pam } plugin { mail_replica = tcp:VMAILSERVER1:12345 } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0666 } } service auth { unix_listener auth-userdb { mode = 0777 } } service doveadm { inet_listener { port = 12345 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_ca = </etc/pki/tls/certs/chain.crt ssl_cert = </etc/pki/tls/certs/ca.crt ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_verify_client_cert = yes userdb { driver = passwd } verbose_ssl = yes

WP8/Windows 10 mail app can't login, tries double auth
by Nagy, Attila 27 Apr '16

27 Apr '16

Hi, Are there anybody who could make WP8 (and W10 desktop clients it seems) devices working with Dovecot's POP3 server? The conversation looks like this: S +OK ready C CAPA S +OK S CAPA S TOP S UIDL S RESP-CODES S PIPELINING S AUTH-RESP-CODE S USER S SASL PLAIN S . C AUTH S +OK S PLAIN S . C AUTH PLAIN S + C <base64 auth string) S +OK[space] C USER username S -ERR unimplemented First I thought the extra space after that OK causes this, but removing it changed nothing. So these devices try to log in with AUTH PLAIN, then even after a successful login they want to log in again with USER, which gets rejected. The only solution here seems to be giving back -ERR to the client's AUTH command, which makes it try USER instead. I'm not aware of any configuration options which makes this possible. Any other ideas? Thanks,
