Please keep replies on-list. If you removed the compiler flag, how can you get error about compiler flag? Perhaps you need to contact package maintainer?

Configure Dovecot for GSSAPI [formerly: Looking for GSSAPI config]
by Mark Foley 06 Jul '16

06 Jul '16

After a over a year and a half struggling to get Dovecot to do either NTLM or GSSAPI authentication with Samba4 AD/DC, I believe I've finally got it! Thanks to all those in this list who helped: Jan Jurkus, Edgar Pettijohn, Gregory Sloop, Tom Talpey especially Aki Tuomi; and infinite thanks to Achim Gottinger on the SambaList for his patience in working this through with me. Although my purpose was for Dovecot to authenticate mail clients, the configuration settings needed were on the Samba side. I hope a variation of these instructions can eventually make it into: http://wiki2.dovecot.org/Authentication/Kerberos What is essentially missing from the wiki is how to set up the proper Service Principal Names and the subsequent creation of a dovecot useable kerberos keytab file. The wiki comment on "k5principals passdb" was not helpful and largely unintelligble to me. Perhaps like many of you, I have switched from Microsoft SBS and Exchange to Samaba4 and Dovecot/IMAP. The transition was completely transparent to my users, except they needed a separate password for email authentication in the absence of NTLM or GSSAPI working with Dovecot. A mild inconvenience, but I have been on a "quest" to fill that gap. This solution finally takes care of that last piece. The following describes how to create the SPNs and krb5 keytab files using Samba4 which has its own built-in (Heimdal) kerberos. The procedures are probably similar for other facilities such as setspn for Windows, but I've not used those so I won't attempt to discuss those mechanism here. You do need kerberos as the Samba built-in kerberos does not have needed commands like `klist`. My distro (Slackware 14.1) does not come with kerberos (nor, I think, does Ubuntu), but is easily found at: https://slackbuilds.org/repository/14.1/network/krb5/ Ubuntu/Debian: apt-get install krb5-config libpam-krb5 krb5-user ssh-krb5 (perhaps more) After provisioning Samba4, copy the krb5.conf template to /etc/krb5.conf. (Note: the actual docs advise symlinking: ln -sf /usr/local/samba/private/krb5.conf /etc/krb5.conf but I prefer making a copy in case I need to modify things). I've set The /etc/krb5.conf file to world readable. It's default contents are (and these do not need to be changed): [libdefaults] default_realm = HPRS.LOCAL dns_lookup_realm = false dns_lookup_kdc = true where HPRS.LOCAL is my realm, of course use your own. Now, we need a samba user in order to create the necessary SPNs (Server Principal Names): $ samba-tool user create dovecot New Password: Retype Password: User 'dovecot' created successfully Next, add the SPN(s), and create the keytab: $ samba-tool spn add imap/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal imap/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot does not do my (outgoing) SMTP serving, only (incoming) IMAP, but if it did I'd have to create another SPN for smtp: $ samba-tool spn add smtp/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal smtp/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot needs to be able to read the keytab file: $ chgrp dovecot /etc/dovecot/dovecot.keytab $ chmod g+r /etc/dovecot/dovecot.keytab my new keytab: $ klist -Kek /etc/dovecot/dovecot.keytab Keytab name: FILE:/etc/dovecot/dovecot.keytab KVNO Principal ---- -------------------------------------------------------------------------- 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) (and if I also created the spn for smtp I would also have these:) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) DOVECOT SETTINGS: My version: 2.2.15 Of crucial importance is to build dovecot with GSSAPI! That is NOT one of the default settings. In the dovecot build directory: ./configure --with-gssapi=yes Other than that serious build gotcha, settings are pretty simple. Add the following 3 settings to 10-auth.conf: auth_gssapi_hostname = "$ALL" auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi The auth_gssapi_hostname is supposedly not required according to some of the above-listed commentors, but my 10-auth.conf template implies differently, so it can't hurt. gssapi does not require a passdb. Use whatever userdb you want. The dovecot wiki doc has some suggestions, not of which I've tried. I use the 'driver = passwd' for my userdb for unrelated reasons. I couldn't get any of this working until I rebooted the Samba AD/DC-Dovecot server, but that just may have been me not stopping/starting Samba and Dovecot in the right sequence (or, everything happened to start working with a concurrent upgrade to Samba 4.2!). In my WIN7 and Ubuntu Thunderbird clients I selected gssapi/kerberos for the IMAP authenticate method and it works! I've even changed the test user's AD password, just to make sure. Someone please put at least the required info on creating the SPNs and krb keytab file for other poor schmucks like me. Now, if I can get NTLM figured out for the remaining Outlook users ... ! --Mark

Postfix/dovecot: user unrecognized, file permissions being misread

Hello all. Have spent several days following the excellent tutorial: http://www.binarytides.com/install-postfix-dovecot-debian/ but still fail to have the user recognized and am getting log entries that the mail directories are 0755 when I can clearly see that they are 0774. Very puzzling, any help would be deeply appreciated. Best regards, Andy =========== Details =========== • I can add directories under IMAP, so my IMAP login and permissions must be correct. • I can create an outgoing message under IMAP, but clicking SEND just hangs. Logs do not indicate problem. • I clearly can send it a message with smtp.

kqueue crash on FreeBSD with 2.2.25

Hi, 2.2.25 crashes on FreeBSD with a kqueue-related message. I see references to something similar (http://www.dovecot.org/list/dovecot/2012-February.txt) from a couple years ago. I get: Jul 1 10:07:27 imap dovecot: master: Panic: kevent(EV_ADD, READ, 54) failed: Bad file descriptor It's not dumping core, and I get the message even with "protocols =" Downgrading back to 2.2.24 fixes it. What info would be helpful for me to provide here? # Adam -- Adam Weinberger adamw(a)adamw.org http://www.adamw.org

duplicate Mails with dsync replication
by Dennis Kuhn 05 Jul '16

05 Jul '16

Hi! We have some strange replication issues. Some mails are duplicated when expunged. This bug is quite hard to reproduce, it just happens occasionally. It seems somehow related to sieve. When i deleted the sieve script i could not reproduce this behavior. Here are some logs, mjm-100010(a)mydomain.com is an alias for mjm(a)mydomain.com: # Master Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): copy from <lmtp DATA>: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): 4N23HaMVa1fpmQEAJEBNLA: sieve: msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>: stored mail into mailbox 'INBOX' Jun 23 04:52:57 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby4 dovecot: dsync-local(mjm(a)mydomain.com): save: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:21 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 # Replica Jun 23 00:51:42 dobby5 dovecot: dsync-server(mjm-100010(a)mydomain.com): save: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:22 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 The problem is the "dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817" on dobby5 at 04:52:57. This creates a new uid 7817 and the new mail is replicated back to dobby4. But i have no idea what triggers this copy. Any ideas? The dovecot version is 2.2.24. Thanks Dennis

many imap connections issue
by Бауыржан Сахариев 05 Jul '16

05 Jul '16

I'm using dovecot 2.1.7 I'm trying to connect to dovecot by imap via Java mail api. My approach described here <http://stackoverflow.com/questions/37991025/why-iterating-over-all-java-mai…>. Bill Shannon, author of the Java Mail api recommended me to check carefully my server side (I have dovecot at server side). Actually, imap login in loop works but very slow. Each store.connect(login,password) takes about 1 minute. I tried to increase mail_max_userip_connections client_limit and process limit but it didn't help. My dovecot sometimes performs query, sometimes not! My logs: Jul 04 18:23:25 auth: Error: pgsql: Query failed, aborting: SELECT email, 'maildir:/home/mailboxes/maildir/'||maildir as mail,'/home/mailboxes/home/'||maildir as home, 500 as uid, 500 as gid FROM users WHERE email = 'test(a)test.domain.com' Jul 04 18:23:25 auth: Error: sql(test(a)test.domain.com,127.0.0.1,<HGiPY842jgB/AAAB>): User query failed: ERROR: permission denied for relation users My user and password queries: password_query = SELECT email as user, password FROM users WHERE email = '%u' user_query = SELECT email as user, 'maildir:/home/mailboxes/maildir/'||maildir as mail, '/home/mailboxes/home/'||maildir as home, 500 as uid, 500 as gid FROM users WHERE email = '%u' My master conf *Please note, that I'm using same uid!* service imap-login { inet_listener imap { #port = 143 } inet_listener imaps { #port = 993 #ssl = yes } # Number of connections to handle before starting a new process. Typically # the only useful values are 0 (unlimited) or 1. 1 is more secure, but 0 # is faster. <doc/wiki/LoginProcess.txt> #service_count = 1 # Number of processes to always keep waiting for more connections. #process_min_avail = 0 # If you set service_count=0, you probably need to grow this. #vsz_limit = $default_vsz_limit } service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge mailboxes. #vsz_limit = $default_vsz_limit # Max. number of IMAP processes (connections) #process_limit = 1024 } service auth { unix_listener auth-userdb { #mode = 0666 #user = #group = } # Postfix smtp-auth #unix_listener /var/spool/postfix/private/auth { # mode = 0666 #} # Auth process is run as this user. #user = $default_internal_user } service auth-worker { # Auth worker process is run as root by default, so that it can access # /etc/shadow. If this isn't necessary, the user should be changed to # $default_internal_user. #user = root } I'm sure that long login *reason is poor dovecot config* but some things are not clear to me and I can't improve it. 1. Which service are being used when Java connects to dovecot? imap-login,imap or auth? My assumption - imap-login. Imap user for dealing with folders *after* login, auth is for delivery (my assotioations here are postfix,lmtp,lda) =) Is my assumptions about imap-login and other services correct? 2. Which user are being used when I login? One that specified in connection code(one of 50K users in loop) or uid(500) user? I suggested that only one user and increased mail_max_userip_connections is it correct? 3. May some troubles in connection (which I showed above) caused by mode(0660) bad config in master.cf services? 4. Almost each loop iteration connects to dovecot in 60 seconds and rarely connects in a few milliseconds. Is that fact somehow connected with deafult_idle_kill which equlas to 1 mins?
