prefetch not working (for me) on ldap user backend
by Hector M. Jacas 26 Apr '15

26 Apr '15

Dear Sir, I'm having problems with the implementation of prefetch userdb. Following the directives from the site (http://wiki2.dovecot.org/UserDatabase/Prefetch) I am unable to avoid the second search to the user backend (ldap). Could give me any advice or tips to achieve my goal? Thanks a lot, Hector M. Jacas My ldap has the following structure: search base: ou=Domains,dc=test,dc=local ******************************* domains tree: domain2.com: dc=domain2.com,ou=Domains,dc=test,dc=local Definition of mailuser1 on domail2.com: dn: uid=mailuser1,dc=domain2.com,ou=Domains,dc=test,dc=local uid: mailuser1 cn: User mailuser1 sn: User 1 displayName: User mailuser1 objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top mail: mailuser1(a)domain2.com ************************************* domain1.com: dc=domain1.com,ou=Domains,dc=test,dc=local Definition of mailuser1 on domain1.com: dn: uid=mailuser1,dc=domain1.com,ou=Domains,dc=test,dc=local uid: mailuser1 cn: User mailuser1 sn: User 1 displayName: User mailuser1 objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top mail: mailuser1(a)domain1.com ************************************* /etc/dovecot/dovecot-ldap.conf.ext content: hosts = ldapserver auth_bind = yes ldap_version = 3 tls = no base = ou=Domains,dc=test,dc=local scope = subtree user_filter = (&(objectclass=inetOrgPerson)(mail=%u)) user_attrs = =home=/var/vmail/mailboxes/%Ld/%Ln/%Ln,=uid=500,=gid=500 default_pass_scheme = CRYPT pass_filter = (&(objectclass=inetOrgPerson)(mail=%u)) pass_attrs = uid=user,password=userPassword,=userdb_home=/var/vmail/mailboxes/%Ld/%8Ln/%Ln, \ =userdb_uid=500,=userdb_gid=500 iterate_attrs = mail=user iterate_filter = (objectclass=inetOrgPerson) ************************************ auth test result for mailuser1(a)domain2.com: # doveadm mailuser1(a)domain2.com password auth test passdb: mailuser1(a)domain2.com auth succeeded Extra fields: user=mailuser1 And in /var/log/maillog (enabled debug auth options): Apr 26 14:00:33 nfs-7-00 dovecot: auth: Debug: auth client connected (pid=0) Apr 26 14:00:33 nfs-7-00 dovecot: auth: Debug: client in: AUTH 1 PLAIN service=doveadm resp=<hidden> Apr 26 14:00:33 nfs-7-00 dovecot: auth: Debug: ldap(mailuser1(a)domain2.com): bind search: base=ou=Domains,dc=test,dc=local filter=(&(objectclass=inetOrgPerson)(mail=mailuser1(a)domain2.com)) Apr 26 14:00:33 nfs-7-00 dovecot: auth: Debug: ldap(mailuser1(a)domain2.com): result: uid=mailuser1;

Auth-worker, Unknown User
by Stephen R Guglielmo 24 Apr '15

24 Apr '15

Hi list, I'm running Debian Jessie (8). I have Postfix and Dovecot working successfully. I attempted to setup LMTP in order to enable sieve support, but it seems I was not successful. Dovecot version 2.2.13. Postfix accepts an incoming test mail I sent, then tries to deliver it to Dovecot via LMTP: dovecot: lmtp(13493): Connect from local dovecot: auth-worker(13495): pam(srg(a)example.com): unknown user dovecot: lmtp(13493): Disconnect from local: Successful quit Postfix then bounces my mail with a "550 User doesn't exist." It seems that Dovecot is trying to lookup my whole address (srg(a)example.com) in PAM instead of just the username ("srg"), which does exist. What can I do to avoid this? I have searched the internet about this and found a few references to "args = %s" and "args = username_format=%n" for passdb and/or userdb, but I have tried both (restarting Dovecot) to no avail. Thank you! `doveconf -n` below: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab103.6 x86_64 Debian 8.0 auth_verbose = yes first_valid_uid = 1000 last_valid_uid = 1000 listen = 167.114.96.243, 2607:5300:100:200::fce lmtp_save_to_detail_mailbox = yes mail_location = maildir:~/Maildir 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 { driver = pam } plugin { recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 0 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/ssl/private/dovecot.cacert.pem ssl_cipher_list = HIGH:!aNULL:!eNULL:!EXP:!SSLv2 ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/private/dovecot.privkey.pem ssl_prefer_server_ciphers = yes ssl_protocols = TLSv1 TLSv1.1 TLSv1.2 userdb { driver = passwd } protocol lmtp { mail_plugins = sieve }

Hi, at moment I have this environment: CentOS nginx + phpfpm Dovecot, with Maildir format Postfix Roundcube MySQL backend about 10000 mailusers dual core Intel(R) Pentium(R) D CPU 3.00GHz 8 GB RAM network storage device (Coraid), ext4 file system I have no performance issue now, but I need to move to a different server: FreeBSD 10.1-RELEASE nginx + phpfpm Dovecot Postfix Roundcube dual core Intel(R) Xeon(R) CPU 5120 @ 1.86GHz 16 GB RAM local storage with zfs file system My question is: is better to use SQLite instead of MySQL? Should I prefer dbox format? Thank you in advance for your opinion!

[BUG] imap-login segfault when running nmap -sV
by Florian Pritz 24 Apr '15

24 Apr '15

Hi, I've noticed that nmap crashes my imap-login (also pop3-login) and narrowed it down to `nmap -sV -p 993 $host`. I've noticed that if I remove "ssl_protocols = !SSLv2 !SSLv3" from my config or enable SSLv3 rather than disabling it the segfault disappears. I'm running on Arch Linux with dovecot 2.2.16-1 and openssl 1.0.2.a-1. I've also attached a network capture, but since it's SSL this probably won't help all that much. I hope this is enough information to reproduce the issue. If necessary I can recompile dovecot with debug symbols for a better backtrace.

acl and lazy_expunge plugins are incompatible?
by Paolo Cravero 24 Apr '15

24 Apr '15

Hello list. Following two previous unanswered requests (http://www.dovecot.org/list/dovecot/2014-August/097449.html and http://www.dovecot.org/list/dovecot/2014-May/096261.html) I fell into the same problem: ACL and lazy_expunge plugins do not work together. I had lazy_expunge enabled working OK. Then I activated ACL plugin, and gave dovecot.2 visibily over paolo.cravero's Inbox: the IMAP connection fails on server-side. Relevant debug log is: Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: Quota grace: root=User quota bytes=576716800 (10%) Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: dict quota: user=paolo.cravero(a)csi.it, uri=file:/maildata1/home/csi.it/p/paolo.cravero/dovecot-quota, noenforcing=0 Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: fs: root=/maildata1/main/csi.it/p/paolo.cravero, index=/maildata1/indexes/csi.it/p/paolo.cravero, indexpvt=, control=, inbox=, alt=/maildata1/altstorage/csi.it/p/paolo.cravero Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: initializing backend with data: vfile Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: acl username = paolo.cravero(a)csi.it Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl: owner = 1 Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Debug: acl vfile: Global ACLs disabled Mar 3 15:59:02 tst-msg03 dovecot: imap(dovecot.2(a)csi.it): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' Removing the lazy_expunge, ACLs do work as expected and I can add/remove/use them. Is there a known compatibility issue? Or there's something wrong in my config and someone else is running with both plugins enabled?
