Unable to see virtual users
by Randall Gellens 01 Dec '14

01 Dec '14

I have a new Dovecot v2.2.9 installation and am having trouble getting virtual users recognized. Also, the example configuration listed on the Wiki generates config errors. Note that I haven't tried running dovecot yet, I wanted to verify that the config looked good first. First, my configuration. I'm trying to use /etc/dovecot/users as my combined userdb and passdb file, with all users having a UID/GID of vmail, and a home directory of /local/mnt/home/<user> ---------- $ sudo doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-39-generic x86_64 Ubuntu 14.04.1 LTS ext4 auth_verbose = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mdbox:/local/mnt/mail/%n managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = randy(a)qti.qualcomm.com protocols = " imap sieve pop3" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail home=/local/mnt/home/%n driver = passwd-file } userdb { driver = passwd } ---------- Next, my /etc/dovecot/users file: $ cat /etc/dovecot/users fred:x test:{SSHA}amehbJZYxKWuIbywINVNWxKcPrWi27a+ poptest2:x poptest3:x ---------- If I ask dovecot what it knows about user 'test' it says the user doesn't exist: $ sudo doveadm user test field valueuserdb lookup: user test doesn't exist ---------- If I ask about a user in /etc/passwd, it finds it: $ sudo doveadm user nobody field value uid 65534 gid 65534 home /nonexistent mail mdbox:/local/mnt/mail/nobody system_groups_user nobody ---------- As an aside, when I copied the sample config entries from http://wiki2.dovecot.org/UserDatabase it got config errors: userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users default_fields = uid=vmail gid=vmail override_fields = skip = never result_failure = continue result_internalfail = continue result_success = return-ok } The 'skip', 'result_failure', etc. entries all generated config errors as being unknown. Since these were just explicitly setting config variables to their default values, I deleted them.

Working with Active Directory on Windows Server 2012 R2
by Aaron Jenkins 30 Nov '14

30 Nov '14

Hi all, I’m having issues getting Dovecot to work with AD on 2012 R2 in a test environment. Background: AD is running on dc1.ad.automaton.uk<http://dc1.ad.automaton.uk>, the domain is ad.automaton.uk<http://ad.automaton.uk>. The DNS server is running on ad.automaton.uk<http://ad.automaton.uk> and the automaton.uk<http://automaton.uk> DNS is set up correctly in the test environment in that everything resolves to the correct IP address and I can authenticate with whichever LDAP clients (ldapsearch, ApacheDS, sssd). It refuses to bind on Dovecot for some reason. aaron@mail:/var/log$ uname -a Linux mail.ad.automaton.uk 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux aaron@mail:/var/log$ dovecot --version 2.2.9 aaron@mail:/var/log$ dpkg -l | grep dovecot ii dovecot-core 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - core files ii dovecot-gssapi 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - GSSAPI support ii dovecot-imapd 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-ldap 1:2.2.9-1ubuntu5 amd64 secure POP3/IMAP server - LDAP support aaron@mail:/var/log/$ cat dovecot-debug.log … Nov 19 09:22:23 auth: Debug: auth client connected (pid=10345) Nov 19 09:22:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:23 auth: Debug: client passdb out: CONT 1 Nov 19 09:22:23 auth: Debug: client in: CONT 1 (previous base64 data may contain sensitive data) Nov 19 09:22:29 auth: Debug: client passdb out: FAIL 1 user=aaron.jenkins temp Nov 19 09:22:29 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:39 auth: Debug: client passdb out: FAIL 2 user=aaron.jenkins temp Nov 19 09:22:40 auth: Debug: client in: AUTH 3 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 Nov 19 09:22:44 auth: Debug: client passdb out: CONT 3 Nov 19 09:22:44 auth: Debug: client in: CONT 3 (previous base64 data may contain sensitive data) Nov 19 09:22:50 auth: Debug: client passdb out: FAIL 3 user=aaron.jenkins temp Nov 19 09:22:50 auth: Debug: client in: AUTH 4 PLAIN service=imap secured session=pkJxdDkISwAK0zcd lip=10.211.55.33 rip=10.211.55.29lport=993 rport=56395 resp= (previous base64 data may contain sensitive data) Nov 19 09:22:56 auth: Debug: client passdb out: FAIL 4 user=aaron.jenkins temp (I’ve removed the base64 as it might contain passwords I actually use, if it’s important I’ll re-run it with a different password unredacted) Do you guys have any ideas on how to get it working with 2012 R2? I know the LDAP is quite funky but I suspect that’s why it doesn’t work. Also, attached is my sssd config as it’s working fine in case it might provide any insights.

how to start a replication master-master correctly
by Eduardo Casarero 28 Nov '14

28 Nov '14

Hi all, I currently have one dovecot 2.2.15 working and I would like to add a second master server. If I configure the second server and enable the dsync in both servers, the sync will copy everything from A to B ? I mean, B server won't remove messages in A as it doesn't have anything in its users mailbox? The second master server will be a cold server just for contingency. Thanks

Move mail behavior
by Martin Stigge 27 Nov '14

27 Nov '14

Hi! I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the old behavior. I observe this with Evolution as well as Icedove (Thunderbird) mail clients, which is why I assume that it's actually a change in the IMAP server behavior. Is it supposed to behave like that? Is there a way to configure this? Regards, Martin
