SOGo - Scaleable OpenGroupware.org

http://www.sogo.nu

SOGo is a groupware server built around OpenGroupware.org (OGo) and the SOPE application server. It focuses on scalability.

SOGo provides a rich AJAX-based Web interface and supports multiple native clients through the use of standard protocols such as CalDAV, CardDAV and GroupDAV.

Once configured, SOGo offers multiple ways to access the calendaring and messaging data. Your users can either use a web browser, Mozilla Thunderbird, Apple iCal, or a mobile device to access the same information.

There is a separate Howto for installing the Funambol middleware that allows SyncML mobile device synchronisation with SOGo.

Requirements

SOGo requires SME 8 (beta 5)

Install

Adding the repository to your SME Server 8:

db yum_repositories set sogo repository \
     BaseURL http://inverse.ca/downloads/SOGo/RHEL5/i386 \
     EnableGroups yes \
     GPGCheck no \
     Name "Inverse SOGo Repository" \
     Visible yes \
     status disabled

db yum_repositories set nethsme repository \
     BaseURL http://smeserver.nethesis.it/releases/8/i386 \
     EnableGroups yes \
     GPGCheck yes \
     Name "Nethesis SME Repository" \
     Visible yes \
     status disabled

signal-event yum-modify

Installing the GPG key to verify the packages:

wget http://smeserver.nethesis.it/releases/RPM-GPG-KEY-nethesis
rpm --import RPM-GPG-KEY-nethesis

Then you can install smeserver-sogo package

yum install smeserver-sogo --enablerepo=nethsme --enablerepo=sogo

Once you have installed SOGo you may find that there is a timeout issue in that SOGo keeps logging you out. To stop this, you will need to add the following line to the .GNUstepDefaults file

OCSSessionsFolderURL = "mysql://sogo:{$sogod{'DbPassword'}}@localhost/sogo/sogo_sessions_folder";

To do this you need to edit the following file in your favourite editor:

/etc/e-smith/templates/home/sogo/GNUstep/Defaults/.GNUstepDefaults/10defaults 

I would put it under the SOGoProfileURL = "mysql://sogo:{$sogod{'DbPassword'}}@localhost/sogo/sogo_user_profile"; line.

Once saved, then execute the following commands:

signal-event sogo-modify;
/etc/rc7.d/S85sogod restart

Hopefully now you will no longer experience the time-out issue.

Upgrade

Upgrade to a later SOGo version (here: upgrade to 1.3 which was released on 21.7.2010)

yum update --disablerepo=* --enablerepo=sogo
/etc/rc7.d/S85sogod restart

Usage

To access webmail and calenders, open the url http://yourdomain.net/SOGo

Thunderbird Configuration

You are encourage to use Thunderbird ESR (Extended Support Release) and corresponding compatible Lightning plugin. According to Mozilla Team "Thunderbird Extended Support Release (ESR) is intended for groups who deploy and maintain the desktop environment in large organizations such as universities and other schools, county or city governments and businesses". Furthermore the latest releases of Lightning plugin is fully SOGo compatibile, so no more need of a SOGo customized version.

1.) From a Windows client create the folder "SOGo-plugins\WINNT_x86-msvc" in your Primary ibay "html" folder (e.g. \\<SME server name>\Primary\hmtl\SOGo-plugins\WINNT_x86-msvc)

2.) Download the latest Lightning, Connector and Integrator plugins from [1] and place them in the "WINNT_x86-msvc" folder.

3.) Rename "sogo-integrator-<version>-sogo-demo.xpi" to "sogo-integrator-<version>-sogo.xpi". (This is optional)

4.) Open the "sogo-integrator-<version>-sogo.xpi" file with your favorite zip program (it is just a renamed zip file. 7-zip works nicely for this) and edit the file "\chrome\content\sogo-integrator\extensions.rdf".

Change the following lines:

       <Seq about="http://inverse.ca/sogo-integrator/extensions"
          isi:updateURL="http://sogo-demo.inverse.ca/plugins/updates.php?plugin=%ITEM_ID%&version=%ITEM_VERSION%&platform=%PLATFORM%">
          <li>
            <Description
              em:id="sogo-integrator@inverse.ca"
              em:name="SOGo Integrator"/>
          </li>
          <li>
            <Description
              em:id="sogo-connector@inverse.ca"
              em:name="SOGo Connector"/>
          </li>
        </Seq>

To read: (change the server address to your server and add the Lightning plugin to the extensions list): (Then save the "extensions.rdf" back to the same place in the "sogo-integrator-<version>-sogo.xpi" file and then save the .xpi file back on the server in the "\\<SME server name>\Primary\hmtl\SOGo-plugins\WINNT_x86-msvc" folder.)

       <Seq about="http://inverse.ca/sogo-integrator/extensions"
          isi:updateURL="http://<sme server name.domain>/SOGo-plugins/updates.php?plugin=%ITEM_ID%&version=%ITEM_VERSION%&platform=%PLATFORM%">
          <li>
            <Description
              em:id="sogo-integrator@inverse.ca"
              em:name="SOGo Integrator"/>
          </li>
          <li>
            <Description
              em:id="sogo-connector@inverse.ca"
              em:name="SOGo Connector"/>
          </li>
          <li>
	      <Description
		em:id="{e2fda1a4-762b-4020-b5ad-a41df1933103}"
		em:name="Lightning"/>
          </li>
        </Seq>

5.) Create the file "updates.php" in the "SOGo-plugins" folder

6.) Add the following lines to the file: (Please note you must customize the "version =>", "filename =>" and "<em:updateLink>http://<sme server name.domain>/SOGo-plugins/<?php echo $plugin["filename"] ?></em:updateLink>" in the lines below!)

(You will have to update this file everytime you update the plugins.)

7.) Install the Thunderbird and configure it to use the SME IMAP email

8.) Install the "sogo-integrator-<version>-sogo.xpi" plugin you modified, into Thunderbird and restart Thunderbird. Sogo will then go to the server and install the other plugins as configured in your "updates.php" file.

Now you can create and share address books and calendars in Thunderbird with other SME users and control access rights to them. Your calendars and address books will also sync with the SOGO webmail page as well as any other computers where you have the SOGO Integrator plugin installed.

To configure other devices refer to website

The memcached - libevent nightmare

Many users have experienced the following errors while trying to install/update SOGo or updating system with yum update:

memcached-1.4.2-1.el5.i386 from sogo has depsolving problems
 --> Missing Dependency: libevent-1.1a.so.1 is needed by package memcached-1.4.2-1.el5.i386 (sogo)
Error: Missing Dependency: libevent-1.1a.so.1 is needed by package memcached-1.4.2-1.el5.i386 (sogo)

To solve this issue you need to install memcached form Epel repository according to wiki http://wiki.contribs.org/Epel
