[Dovecot] userdb prefetch problem..
by Mike 10 Aug '06

10 Aug '06

I have a setup that I'm working on migrating to Dovecot for thousands of users across a few dozen domains.. All users are authed from LDAP.. In LDAP, each user has a unique uidNumber, and varying gidNumber (for use in other applications) As far as mail storage, the entire Maildir structure is owned by UID/GID: vmail/vmail So, the uidNumber/gidNumber from LDAP is not needed. global uid/gid is set to 'vmail' When using "passdb ldap" and "userdb ldap" both pointing to dovecot-ldap.conf, and removing the "uidNumber=uid"..etc from the "_attrs" lines, this works just fine. I would like to use "userdb prefetch" to use one less ldap query, but the uid/gid stuff is giving me some problems. The appropriate line in - dovecot-ldap.conf: pass_attrs = mail=user,userPassword=password,homeDirectory=userdb_home I get the following erros in the log: .... .... dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_uid not returned dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_gid not returned dovecot: auth(default): userdb(user(a)domain.com,127.0.0.1): user not found from userdb dovecot: auth(default): master out: NOTFOUND 1 dovecot: pop3-login: Internal login failure: user=<user(a)domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any help is appreciated! -Mike FreeBSD 6-1-RELEASE OpenLDAP 2.3 Dovecot 1.0rc2

[Dovecot] 1.0 RC1 status
by Timo Sirainen 10 Aug '06

10 Aug '06

Today I finally caught up with my mail. I've now read all the mails from the Dovecot list from this year and all my private mails from last few years (totaling around 500 unread mails). If you think there's still something I should have replied to, please re-send it because I've either missed it or just skipped it for some reason. (Except there are still a couple of mails from this week I've yet to reply to.) Besides reading mails I've also fixed a lot of bugs today. What's left from my original 1.0 roadmap is: - Solaris sendfile is broken? Is it? Can someone try? You can test it with maildir by setting mail_save_crlf=yes, saving a somewhat large mail and FETCHing it (and truss that it really uses sendfile) - LDA: empty mail gives an error. - quota code should probably be always doing some quota_set_critical() instead of using mail_storage_set_critical(), so that quota_last_error() would work properly - rfc2557 support for BODYSTRUCTURE, as specified by RFC3501 - keywords: add some limits to how many there can be - don't return \* in PERMANENTFLAGS when we're full - mbox: how well does dirty sync + status work? it reads the last mail every time? not very good.. - mbox: dirty state should be stored to index (with mbox_very_dirty_syncs) I think 1.0 could be released without any of those changes. But what about the connection hangs that some people have had? Do they still occur? Is it only with SSL? I guess I should look at my previous ssl-proxy rewrite, figure out what went wrong with it and try again. I'm thinking about releasing 1.0 RC1 within a few days. Would be nice if that release actually worked, so testing would be appreciated :) You can try it by getting the dovecot-latest from http://dovecot.org/nightly/ The current changes include: * PAM: If user's password is expired, give "Password expired" error message to the user. Now actually working thanks to Vaidas Pilkauskas * Relicensed dovecot-auth, lib-sql and lib-ntlm to MIT license. See COPYING file for more information. * Abuse prevention: When creating a mailbox, limit the number of hierarchies (up to 20) and the length of the mailbox name within a hierarchy (up to 200 characters). * mbox: If saved mail doesn't end with LF, add it ourself so that the mails always have one empty line before the next From-line. + Added --with-statedir configure option which defaults to $localstatedir/lib/dovecot. ssl-parameters.dat is permanently stored in that directory and is copied to login_dirs from there. + IMAP: Support SASL-IR extension (SASL initial response) + Support initial SASL response with LOGIN mechanism. Patch by Anders Karlsson + Added PLAIN-MD4 password scheme. Patch by Andrey Panin. + Added support for XFS disk quotas. Patch by Pawel Jarosz + If another process deletes the opened mailbox, try to handle it without writing errors to log file. Handles the most common cases. + Added TLS support for LDAP if the library supports it. - Dovecot corrupted mbox files which had CR+LF linefeeds in headers - MySQL code could have crashed while escaping strings - MD4 code with NTLM authentication was broken with 64bit systems. Patch by Andrey Panin - Plugin loading was broken in some OSes (eg. FreeBSD) - Several fixes to handling empty values in configuration file - Several fixes to dictionary quota backend and dict server. Also changed how they're configured. - deliver: Fixed plugin handling settings - mbox_min_index_size handling was somewhat broken - passdb passwd-file: extra_args field wasn't read unless the file was also used as userdb.

[Dovecot] Dovecot and MySQL auth - initial setup issues
by Andrew Hearn 10 Aug '06

10 Aug '06

Hello, I'm just setting up a new server and wanting to use MySQL for user authentication. Here is what I have: Fedora Core 5: 2.6.17-1.2145_FC5 Dovecot v1.0.rc2 (RPM install from atrpms.net) MySQL v5.0.22 SquirrelMail v 1.4.6-7.fc5 ...Running on a Dual XEON machine I've added the following to dovecot.conf: auth default { passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } The rest of dovecot.conf is standard. /etc/dovecot-mysql.conf has: driver=mysql connect = host=127.0.0.1 port=3306 dbname=maildb user=root client_flags=0 password_query = SELECT password FROM users WHERE id = '%u' user_query = SELECT maildir FROM users WHERE id = '%u' (I've run the SQL queries within mysql and they give the right results) When I start Dovecot the log shows: dovecot: Jul 11 12:47:25 Info: Dovecot v1.0.rc2 starting up dovecot: Jul 11 12:47:27 Info: auth-worker(default): mysql: Connected to 127.0.0.1 (maildb) When I try to log in using SquirrelMail, it takes about 3 seconds, then I get dovecot: Jul 11 12:48:00 Info: imap-login: Aborted login: user=<andrew(a)mail-test.aaisp.net.uk>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured ...So, no log of it trying MySQL... And SquirrelMail then says: Unknown user or password incorrect Any ideas of what I'm missing? Thanks!

[Dovecot] no protocols inhibits dovecot --exec-mail
by Johannes Berg 10 Aug '06

10 Aug '06

Hi, Running the current debian unstable version (1.0.beta2) dovecot tells me: $ /usr/sbin/dovecot --exec-mail imap Error: No protocols given in configuration file Could this be changed? I don't need dovecot listening on any ports but would still like to allow this usage... Or should I configure protocols but no listen addresses instead? [if so the debian package needs an update because it filters out the case of no protocols and doesn't start dovecot in that case] johannes

[Dovecot] Duplicate e-mails
by Lisa Wu 10 Aug '06

10 Aug '06

Hi, I've got Postfix/Dovecot config mail server, POP3/mbox, and a few users are complaining about duplicate e-mails. User connects with Outlook 2003 to Dovecot to download mail. If you check the mail logs for that message ID, only one copy is delivered to his mailbox. Also, verified that the client is set-up to NOT leave a copy of the message on the server. He downloads a copy of the e-mail once, and then 2 minutes later when his client reconnects to check for mail, he gets another copy of that e-mail. It's not a consistent problem. I check the dovecot logs, and see his client connecting and disconnecting, and always deleting the same number of e-mails it downloads. Is this a network issue or a config issue? The only other thing to note is that it's usually an e-mail sent to a group list that he's a member of. And I've set-up the owner-list setting in the aliases file. So I don't think that's the problem. If anyone can shed some light on this issue, it'd be greatly appreciated. Thanks, Lisa
