[SOGo] SOGo with Plesk/Dovecot on Ubuntu 14
Hi all, I try to install SOGo on my Ubuntu 14-Server with Plesk Panel for a while now and I come to the login screen successful and have created a user in openLDAP that can authenticate.

[SOGo] Upgrade 3.2.15 -> 4.0.5: Database problems

Re: [SOGo] Upgrade 3.2.15 -> 4.0.5: Database problems
Hi all, thanks for your answer, Christian. /usr/sbin/sogo-tool dump-defaults returns some parts of my sogo.conf containing my database password. But actually, I cannot find any .GNUstepDefaults, neither in /root/GNUtep/Defaults nore somewhere else. plparse /etc/sogo/sogo.conf returns "Parsing '/etc/sogo/sogo.conf' - a dictionary" as expected. And yes, I ran the db-upgrade but tried it again just now. This time, I get: root@www:/usr/share/doc/sogo# ./sql-update-3.2.10_to_4.0.0-mysql.sh Username (root): sogo Hostname (127.0.0.1): Database (sogo): This script will ask for the database password twice Converting c_content from TEXT to LONGTEXT in the sogo_user_profile table Converting c_mail from VARCHAR(255) to TEXT in Contacts quick tables Enter password: Enter password: ERROR 1060 (42S21) at line 1: Duplicate column name 'c_hascertificate' ERROR 1060 (42S21) at line 1: Duplicate column name 'c_hascertificate' [...] Thanks in advance, Carsten Am 17.01.19 um 09:05 schrieb Christian Mack (christian.m...@uni-konstanz.de): Am 16.01.19 um 23:15 schrieb Carsten Pieper (i...@carstenpieper.com): Hi dear community, today, I upgraded from SOGo 3.2.15 to 4.0.5 and everything worked.

[SOGo] could not open storage channel

Re: [SOGo] could not open storage channel
Thanks a lot, Odhiambo, but that is exactly my problem. I have specified User A in my sogo.conf, but in the logs, I see, that the default user 'sogo' is used. I have set the password of the user 'sogo' to the password prompted out in the dump-defaults. I can authenticate via mysql console with User A and user sogo. Now, I change the password of user 'sogo' to 'sogo'. I can authenticate with the new password via mysql console, the errors in the log disappear and the calendar entries are back again. Thus, where in the system do I find the defaults dumped out?

[SOGo] Question regarding OpenChange package on Xenial
Hi all, I'm actually migrating my SOGo installation from trusty to xenial. Trying to install the necessary packages results in: E: Package 'sogo-openchange' has no installation candidate This is my relevant entry in the sources.list: deb http://www.axis.cz/linux/debian xenial sogo-v4 openchange What am I doing wrong?

Re: [SOGo] Question regarding OpenChange package on Xenial
Ok, then, I need some more explanation. I was running SOGO 3 on Ubuntu 14 without having openchange installed. SOGO was working fine, with Outlook and Exchange ActiveSync. But because of some performance troubles, I had the idea to upgrade to SOGo 4. The performance problems have not been solved, and I cannot connect from Outlook anymore. Am I right, that SOGo v4 needs openchange to connect to Outlook, but SOGo v3 not? If so, would it be better to install SOGo 3 on the new server with ubuntu 16? I have already installed v4 there, can I downgrade without troubles? Will SOGo v3 be supported in the future or am I riding a dead horse?

Re: [SOGo] Question regarding OpenChange package on Xenial
Hi mj, hi all, referring to https://sogo.nu/files/docs/v3/SOGoNativeOutlookConfigurationGuide.html#_installation, it says in Chapter 5 I have to install sogo-openchange and several more. I do not find anything regarding sogo-activesync there. So, am I right with the following thesis: "SOGo v4 supports Outlook/ExchangeActiveSync via installing the package sogo-activesync, i.e. following https://sogo.nu/files/docs/SOGoInstallationGuide.html. It is not necessary to follow the NativeOutlookConfigurationGuide, neither for v3 nor v4, to have Outlook connected to SOGo without any plugin." But for what do I than need the Native Outlook Configuration Guide?

Re: [SOGo] Problems with a fresh install of SOGO 4.0.7 on ubuntu 16
Hi Odhiambo, thanks for your answer, I'm running on MySQL and can actually log in to the database from console with the user configured in the conf. sogo-tool dump-defaults does not return anything. I was looking in nginx because it feels for me that something before SOGo is not running correctly yet. Other LogLevel or Debug options in sogo.conf do not help, wihich makes me even more think that the problem is caused somewhere in Apache or Nginx, not in SOGo. I do not find any request in SOGo.log, it just says it started fine and that was it. Any other ideas are really appreciated, I think it's something really stupid :-), Thanks a lot, Carsten Am 13.03.19 um 14:04 schrieb Odhiambo Washington (odhia...@gmail.com): On Wed, 13 Mar 2019 at 15:48, Carsten Pieper <mailto:users@sogo.nu>> wrote: Hi all, sorry, I think I have quite a stupid question this time.

I assume, you're using nginx. As I've already written[1], the error message is a consequence of bigger header data. You'll need to update the buffer values in your nginx config: proxy_buffer_size 8k; proxy_buffers 4 64k; To find the error message, just check your nginx error log. In my case, the following got logged to sogo.log: [ERROR] <0xX[WOHttpTransaction]> client disconnected during delivery of response for (len=50): the socket was shutdown and nginx' error log: *123456 upstream sent too big header while reading response header from upstream, client: ip.add.re.ss, server: sogo.example.com, request: "POST /SOGo/connect HTTP/1.1", upstream: "http://127.0.0.1:2/SOGo/connect";, host: "sogo.example.com", referrer: https://sogo.example.com/SOGo/"; After increasing the buffer size and reloading nginx it worked again. (btw. do not forget to upgrade your database scheme as this is required for 5.5.1 -> 5.6.0 upgrade). -- Adi [1] https://www.mail-archive.com/users%40sogo.nu/msg31359.html -- users@sogo.nu https://inverse.ca/sogo/lists -- users@sogo.nu https://inverse.ca/sogo/lists
