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 However, nowadays this just seems outdated and makes contact pictures useless as they are too chuncky to allow recognition anyways.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?

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 / 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

« on: December 26, 2015, 11:46:42 pm »

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.
