[Dovecot] Dovecot unable to access the shadow file
by kenwood 25 Jan '13

25 Jan '13

I am installing Dovecot-2.1.13 on Slackware 13.37.0 for the first time to replace ipop3d and I have overcome all of the roadblocks as they have developed except this last one and I finally have to say “uncle”. The error messages that are showing up in the dovecot.log are as follows. Jan 24 12:27:27 tux2 dovecot: auth: Error: passwd-file /etc/shadow: open(/etc/shadow) failed: Permission denied (euid=202(dovecot) egid=202(dovecot) missing +r perm: /etc/shadow, we're not in group 43(shadow), dir owned by 0:0 mode=0755) Jan 24 12:27:27 tux2 dovecot: auth: passwd-file(user,192.168.10.2,<pw3xHwzUSQDAqAoC>): no passwd file: /etc/shadow Jan 24 12:27:29 tux2 dovecot: pop3-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.10.2] Jan 24 12:27:29 tux2 dovecot: pop3-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<user>, method=PLAIN, rip=192.168.10.2, lip=192.168.10.100, TLS: Disconnected, session=<pw3xHwzUSQDAqAoC> Based on what I have read the only user that should access the shadow file is root. With that in mind I looked at all the configuration and .ext files and the only file I could find that would indicate that root should be checking the shadow file is 10-master.conf. In that file it said the default service auth-worker was root but since it was apparently not working I removed the hash mark and made it explicit. It still didn’t work. As a last resort even though it was not good practice I tried adding user dovecot to the group shadow but that did not work either. It still says dovecot is not in the group shadow even though it is. Any suggestions? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-unable-to-access-the-shadow-fi… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dovecot 2.1.13, proxy and nologin extras field
by Marco Giunta 24 Jan '13

24 Jan '13

Hi at all, in our test environment, I'm playing with dovecot 2.1.13 configured as imap/pop/managesieve proxy. It is configured to authenticate users with ldap and it works very well. Now, I'd like to temporary disable some users's login, because we are moving to another storage, and I wouldn't stop imap service at all. I've found on Dovecot wiki that I could use 'nologin' extra field, but I wasn't been able to get it work. My dovecot configuration is: # 2.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 ... auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_debug = yes 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 mbox_write_locks = fcntl 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 = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } and my 'dovecot-ldap.conf.ext' is: uris = ldap://ldap.example.it/ dn = "cn=Reader,dc=example,dc=it" dnpass = password base = ou=People,dc=example,dc=it pass_attrs = uid=user,userPassword=password,\ =userdb_home=/var/spool/mail/%1u/%u,uidNumber=userdb_uid,gidNumber=userdb_gid,\ =proxy=y,=host=imap.example.it,\ =nologin=y pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) With this configuration, all users can login, and log said: Jan 23 09:16:18 localhost dovecot: master: Dovecot v2.1.13 starting up (core dumps disabled) Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jan 23 09:16:33 localhost dovecot: auth: Debug: auth client connected (pid=3660) Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011session=PsbzT/DT+gCTeiwf#011lip=192.168.129.109#011rip=192.168.44.31#011lport=143#011rport=53754 Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: CONT#0111#011 Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: CONT#0111#011AHByb3ZhZm0AY2hlcGFsbGU= Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,147.122.44.31,<PsbzT/DT+gCTeiwf>): pass search: base=ou=People,dc=example,dc=it scope=subtree filter=(&(objectClass=qmailUser)(uid=prova)(accountStatus=active)) fields=uid,userPassword,uidNumber,gidNumber,uid,uid Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,192.168.44.31,<PsbzT/DT+gCTeiwf>): result: uid=prova uidNumber=2944 gidNumber=650 userPassword={MD5}BjbsTtSovVAs1csswBTI7Q== Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: OK#0111#011user=prova#011proxy#011host=imap.example.it#011nologin#011hostip=192.168.11.136#011pass=password Jan 23 09:16:33 localhost dovecot: imap-login: proxy(prova): started proxying to imap.example.it:143: user=<prova>, method=PLAIN, rip=192.168.44.31, lip=192.168.129.109, session=<PsbzT/DT+gCTeiwf> As you can see 'nologin' field is present in 'passdb' answer, but it doesn't seem to work.

[Dovecot] Permissions when running `dovecot --exec-mail imap`
by Tim Marston 24 Jan '13

24 Jan '13

Hi, I'm running dovecot 1.2.15, on Debian squeeze. /var/mail is owned by group "mail" with permissions "g+rwxs,o=". The mail_privileged_group setting is set to "mail". I am trying to access mail on a remote machine with mutt by tunnelling mutt though ssh and running `dovecot --exec-mail imap` on the mail server. But I frequently get errors in the mail server's logs about not being able to create dotlock files when accessing my INBOX this way. This makes sense -- I'm running dovecot as a regular user, so it isn't able to write to /var/mail as group "mail". I notice that on the dovecot wiki[1] it is suggested that sudo is used to set uid/gid before running `dovecot --exec-mail imap`. But I don't actually want to set the uid, just the gid. And I also have sudo disabled at the moment. So I was wondering about another solution... Would it be acceptable to setgid the dovecot executable and change it's group to "mail" (i.e., `chgrp mail dovecot` and `chmod g+s dovecot`)? Would this pose some kind of security risk? Would this actualy do what I want, or am I missing a bigger picture? Kind regards, [1] http://wiki.dovecot.org/PreAuth -- Tim Marston ed.am

[Dovecot] warning regarding quota and mboxes
by Andreas Meyer 23 Jan '13

23 Jan '13

Hello! We drive mboxes and maildirs and the dovecot-server is running very well and everthing is fine, but I get the following warning in the dovecot-lda-errors.log when a mail is delivered to a mbox. Jan 10 16:29:24 lda(archiv(a)bitcorner.de): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota This is what I defined in the dovecot.conf: mail_home = /var/spool/vhosts/%d/%n mail_location = mbox:~/:maildir:~/ mail_plugins = quota plugin { quota = maildir:User quota quota_rule = *:storage=500MB quota_rule2 = Trash:storage=+10%% } Can I avoid the error above somehow? Namespaces are a bit mysterious for me at the moment. Greetings Andreas

[Dovecot] speed up dovecot IMAP server
by Bernics Gábor | Penta Unió Zrt. 23 Jan '13

23 Jan '13

Hello, I upgraded my dovecot server (1.2 -> 2.1), from debian backport because it was a little slow (wait 5-6 sec) when I opened some mail (but not every mail). Unfortunately, the mail open speed didn't increase. I think it's an index problem. Have you idea for fixing?

[Dovecot] Fixing bad maildir message sizes
by Richard Platel 23 Jan '13

23 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?
