Dovecot + Weakforced Policy server

Hi, I'm trying to set Weakforced with Dovecot and I cannot log in policy server. This is the config: /root/weakforced/wforce/wforce.conf ----------------------------------- ... webserver("0.0.0.0:8084", "super") ... /etc/dovecot/conf.d/95-policy.conf ---------------------------------- auth_policy_server_url = http://localhost:8084/ #auth_policy_hash_nonce = wforce:super auth_policy_hash_nonce = {SHA256-CRYPT}$5$Ue5UrToV.Bam02bQ$Bi9OJ62Mkgc20L2HnLVmD2OCHyXaKje6Hh7qNjnOkB9 I'm following the instructions of Dovecot's wiki: https://wiki.dovecot.org/Authentication/Policy ... "To generate the hash, you concatenate nonce, login name, nil byte, password and run it through the hash algorithm once. The hash is truncated when truncation is set to non-zero. The hash is truncated by first choosing bits from MSB to byte boundary (rounding up), then right-shifting the remainding bits. hash = H(nonce||user||'\x00'||password) bytes = round8(bits*8) hash = HEX(hash[0:bytes] >> (bytes-bits*8)) And I set hash with password (super) in this way: vm-weakforced:~# doveadm pw -p noncewforce\x00super -s SHA256-CRYPT {SHA256-CRYPT}$5$ZWIX2dnU7NJvGHgC$hYFbeCCaHYZv0yPP80GHygxQMPmI5BjMx2ttRe9zti2 But if I log in Dovecot Server: vm-weakforced:~# doveadm auth login usuario Password: passdb: usuario auth succeeded extra fields: user=usuario userdb extra fields: usuario system_groups_user=usuario uid=1000 gid=1000 home=/home/usuario Answer of Weakforced is always "...authentication failed": WforceWebserver: HTTP Request "/" from 127.0.0.1:39720: Web Authentication failed And Dovecot logs don't show anything else: ...

MySQL 8.0: Supported?
by Larry Rosenman 16 Jan '19

16 Jan '19

I got a complaint from a FreeBSD user that they couldn't compile dovecot against MySQL 8.0. Is MySQL 8.0 support with 2.3.4? they receive: checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found ===> Script "configure" failed unexpectedly. Please report the problem to ler(a)FreeBSD.org [maintainer] and attach the "/wrkdirs/usr/ports/mail/dovecot/work/dovecot-2.3.4/config.log" including the output of the failure of your make command. Also, it might be a good idea to provide an overview of all packages installed on your system (e.g. a /usr/local/sbin/pkg-static info -g -Ea). *** Error code 1 thanks! -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 (c) E-Mail: larryrtx(a)gmail.com US Mail: 5708 Sabbia Dr, Round Rock, TX 78665-2106

Import mailbox from different domain
by Sergio Belkin 15 Jan '19

15 Jan '19

Hi folks, Let's say that I have on dovecot the domain example.net and on MS Exchange example.com. I've tried to import a mailbox from MS Exchange to Dovecot but it fails, I've run: dsync -Dv backup -R -u joe.doe imapc: dsync(joe.doe(a)example.net): Error: imapc(192.168.0.2:993): Authentication failed: AUTHENTICATE failed. Is there a way to submit different domains both on MS Exchange and Dovecot and to make everyone be happy :) ? Thanks in advance -- -- Sergio Belkin LPIC-2 Certified - http://www.lpi.org

We do not want, at this moment, take up maintaining and developing yet another FTS plugin as we have plenty of things to do already. I invite you to setup your own repository and provide this plugin from there, being the maintainer of this plugin. We can add a link to your plugin on our FTS page so people can also find it. There are other plugins like this, e.g. https://github.com/st3fan/dovecot-xaps-plugin I turned the code you provided into a separate plugin package. The distribution tarball is attached. Notable changes: - Added example copyright headers and COPYING and AUTHORS files. You should modify those to your preference. - Added README and INSTALL files (in markdown using Pandoc). Those need to be amended with details. - Amended the plugin code to display a debug message with the plugin name and version upon plugin load. I advise you to turn this into a git repository and continue from there. I do not recommend releasing this plugin with the -fpermissive flag and the resulting warning as it is now. But I'm assuming this is still a work in progress, so that is OK. Regards, Stephan.

I will definitely appreciate that this is added in the core git of docevot, in order to have a versionning of it, to remove squat and let basic users able to avoid Solr alternative as much as possible. Thanks JM Hi! I still recommend you setup a, say, github repository for your plugin. We are not able to currently include your work in dovecot core as it is more work than just pushing the code into the repo. Maybe it can be included in the future. If you want, I can help you in setting up the required configuration scripts and such to make it possible to compile it as plugin. Then anyone can download it and install it for their dovecot, even if dovecot itself has been installed from packages, and also makes it possible for package maintainers to consider including it in distributions.

What does the mdbox_rotate_size influence?
by Marc Roos 14 Jan '19

14 Jan '19

I wondered why mdbox_rotate_size is 2MB by default. I thought if I increased it to 16MB, maybe there would be less disk io, but I dont see any difference. Furthermore I read in some thread that increasing it from 2MB, could give problems when deleting messages, can someone explain this? Does anyone have this on a cephfs mount, does it make sense to set this to 4MB?

mdbox import error from read-only filesystem
by hby 14 Jan '19

14 Jan '19

Dovecot version: 2.2.34 doveadm import tries to call open() on the source indexes/logs of mdbox data, but even if it should work as it is just a read-related call, it fails on read-only filesystems. The main use case for read-only filesystem is restoring from backup: the massive deduplicated backup data is exposed using FUSE. For deduplication to work efficiently, we have to backup the whole mail storage and thus the only way to handle the restore to mount the whole data. I would like to ask for some proper solution for this problem. Suggestions: first, the doveadm import should never modify the indexes, and second: the open() calls should respect the read-only filesystem and should fall back to "r" flag when using open. The problem goes further when using SIS (which goes beyond multiple terrabytes). The only workaround currently is to export the whole mdbox data to a writeable storage, and parametrize the import command to use that and the mounted SIS data separately for import...which is just problematic, ugly and error prune. Thank you for the continous work on dovecot, I hope you get this feedback in a good way.

Hello, I have the following fatal error when I uncomment #!include auth-sql.conf.ext in .../conf.d/10-auth.conf dovecot: auth: Fatal: Support not compiled in for passdb driver 'sql' I have installed via 'pkg'. Do I have to install the ports tree to get sql support ? Thanks, -Graham-
