Hello Florian,

I had the same problem with my first zentyal installation. Openchange got over the course of a week slower and slower until it immediately crashed when there was some load on (With load I mean one web interface instance running).

Apparently, after reinstalling, openchange is faster, however it is still very slow (the webinterface takes sometimes over 2 minutes to completly load (in lan)) and crashes sometimes (~2 times a month). The solution for the crashing was a cronjob which sends a start command to the zentyal-openchange service hourly.

Outlook (2016) still also shows the server down a lot however not all the time. Receiving mails in outlook however even works when the server is shown down. I came around this by using imap instead. Strangely, on a virtual machine (2 cores of my Intel i5-3317U mobile, 1,5GB DDR3) I sat up for testing before changing something on my production server, I don`t have any speed issues. I´m aware that the server has to handle a lot more tasks (dhcp, dns, users, samba filesharing, cups, webmin) than the virtual machine (only openchange and users). However, I´m running less than 10 users (it´s a private server) on a Intel Xeon E3-1230 with 8GB DDR3 and a 250GB Samsung SSD as the system drive so speed issues with this configuration should not happen. Also the CPU load is below 1.0 and I´m barely using a quarter of the available ram.

I haven´t tried any other machines but maybe openchange has problems with different types of cpus?

greetings,

Email and Groupware / Contact Picture Size
« on: March 10, 2016, 08:16:05 pm »
Hello,

I am running zentyal 4.2 community edition on my production server. When syncing contacts between my phone and the server (using active sync), the high resolution contact pictures get scaled down to a very low resolution which was fine back in the old days. However, nowadays this just seems outdated and makes contact pictures useless as they are too chuncky to allow recognition anyways. Is there a way to change this?

Hi trysomething,

unfortunately I didn´t found a solution yet. My plan right now is to wait until the next holidays and then reinstall the whole system. The solution I came up with until that time is to use the "broken" server as a DHCP, DNS, File Server and the virtual machine I created before installing zentyal as my server-os as a mail-server.

Email and Groupware / Openchange crashes
« on: January 03, 2016, 03:36:58 pm »
Hello everybody,

I´m having some troubles with openchange on my zentyal installation. When I reboot the machine, openchange starts and works like it should. After a few minutes, the webinterface is really slow and after a while, it doesn´t even respond anymore. I just get a proxy error (502). On the zentyal modules page, openchange is marked as stopped, however there is no "start" button, just a "restart" button. When I press this, it says it has been restarted correctly, if I however open the dashboard a second time it is marked as stopped again. I have to repeat this step a few times until there is a green "start" button. Then openchange starts correctly and works for the next 2 minutes...

I also tried using shell commands for restarting openchange (sudo /etc/init.d/zentyal openchange restart). It says zentyal has been restarted correctly (no matter if I say start or restart), however, it doesn´t work. On Webmin, I saw that there was a 11gb logfile which I deleted using the zentyal interface. I actually shouldn´t have a hardware problem as there are currently only four users, my machine however has an 2014 Intel Xenon, 8GB DDR3 and a 256GB Samsung SSD as the main drive.

If somebody knows how to deal with this, I would really apreciate if could help me.

BTW,

on a vm installation i made before installing zentyal on my production machine (for testing purpose and getting used to), openchange works like it should.

Installation and Upgrades / Re: Openchange reinstallation fail
« on: January 01, 2016, 04:30:14 pm »
Hello, thanks for your help.

I tried both solutions, unfortunately neither of them worked. Is it possible to delete the whole database and start from the beginning, maybe with reinstalling domain services?

Edit:

I found an old backup from a date when openchange was still working. I installed that. BTW, I noticed the day openchange started to fail the backup size shrinked from ~50MB to ~3MB.

Installation and Upgrades / Openchange reinstallation fail
« on: December 28, 2015, 11:40:21 am »
Hello,

I´ve had some troubles with the openchange module, it always crashed after a few minutes. It was shown as "stopped" on the dashboard and no client could connect. Then, I had to press "restart" a few times until there was a button called "start". Finally, openchange came back online. Because restarting the module every 15 minutes is anyoing, i decided to uninstall mail, mailfilter and openchange from the module selection. I then rebooted the machine and installed them again. Now, Openchange says it needs to be provisioned. However, when I enter an organization name, it says "The PDC server has been already provisioned". I tried reinstalling openchange again, but it just won´t work. I think the problem is that it wants to create new config files but then struggles with the old one fromt the previous installation. Does anybody know where these files are located and if they are safe to delete?

General information:

my installation is a fresh installation running on a real machine with an Intel 64bit, 8GB of RAM and a 256 SSD. I upgraded everything to the latest version using apt get update && upgrade and installing all the updates available on the Zentyal webadmin module. The Zentyal server is not my gateway, however, it is my AD Controller and my DNS/DHCP server.

Thanks to everyone who read this and special thanks in advance to those how help me with the soluton.

Directory and Authentication / [SOLVED] LDAP Password & Owncloud

Solved!! Solution at the end of this post!

Hi every one,

I changed my WS2012R2 to Zentyal 4.2 Development Edition yesterday. I did not migrated users or anything from the old server (except some data but thats probably not important for this problem), its a completly fresh installation. I´m running Ubuntu Linux 14.04.3 (Kernel and CPU: Linux 3.19.0-42-generic on x86_64). It´s a physical machine, it`s the main domain controller and dhcp/dns server. It`s not my firewall, it`s connected to the internet like every other device in my network via my router. I installed the system with the latest CD-Image from the Zentyal-site. I upgraded and installed alll updates available.

Today, I installed Owncloud (onto the preinstalled Apache 2 Server). After the installation, I wanted to use the ldap-backend.  I installed it using this https://www.youtube.com/watch?v=lW2iS3l4568. However, Zentyal 4.x doesn`t show the DN User/Password. Does somebody know if this information is stored somewhere accessable on the filesystem or is there an other solution for this prolem?

I want to say thank you in advance for taking time and helping me.


After a night of searching around the web, I found this https://forum.zentyal.org/index.php?topic=22559.0.

The path to the file, where the password is stored, is: "/etc/postfix/groupaliases.cf".
In my case, the file was only readable as a superuser, so you either have to open it with
Code: [Select]
sudo nano /etc/postfix/groupaliases.cf or you can start your filemanager as a superuser
Code: [Select]
sudo gksu pcmanfm if you prefer the graphical way.
