Groupware

Groupware solutions include shared calendars, group email servers, groups address lists, group projects, and internal messaging. They require (one or more) servers with LAMP or similar server stacks.

Groupware Servers

Groupware servers are meant to operate on a server platform. You should install the server version of Ubuntu (in the interest of speed) for a dedicated groupware server. Read Servers.

Kolab

Kolab is the most comprehensive open-source groupware solution available and is distributed as a multi-platform solution. (It integrates easily with both Ubuntu (including Evolution) and KDE/Kubuntu (including Kontact).) It is free and open source with a GPL license (unlike other groupware solutions), yet enterprise support is also available. It is scalable to large organizations and is Outlook (MS-Exchange) and Mozilla compatible. This is a German package, however, and documentation in English can occasionally be limited. The Kolab website provides its own instructions for installation from source (currently v. 2.2). Version 2.2 includes the Horde web interface. The current beta Debian package instructions are here or the OpenPkg installation instructions are here.

  • Note: Kolab uses its own server components, and it is best to run Kolab on a dedicated server. However, it is possible to run other servers on the same machine, as long as you choose alternate ports if the server modules conflict.
  • Install the compiler and other necessary stuff:
sudo apt-get install build-essential

Kolab Ubuntu package

  • There is an Ubuntu/Kubuntu package for the new version of Kolab (v. 2.2), but no documentation support for it yet exists. Install:
sudo apt-get install kolabd

Manual Kolab installation

  • Make a directory for the Kolab installation and make it universally accessible:
sudo cd /
sudo mkdir /kolab
sudo chmod 777 /kolab
  • Optional: If you wish to mount kolab in its own partition, then create a new partition (using Gparted, for example). Figure out the device name of your extra partition:
sudo fdisk -l
It should be something like /dev/sda3.
Mount /dev/sda3 (or whatever your partition is) as /kolab by editing /etc/fstab:
sudo nano /etc/fstab
and adding the line:
/dev/sda3  /kolab  ext3  defaults,rw 0 0
then reboot and make sure there are no errors.
  • Make a directory into which to download kolab:
cd /tmp
mkdir /kolabtmp
  • Download all the current Kolab files:
cd /tmp/kolabtmp
wget -r -l1 -nd --no-parent http://files.kolab.org/server/release/kolab-server-2.2.2/sources/
  • Install Kolab (as root using sudo -s):
sudo -s
sh install-kolab.sh 2>&1 | tee kolab-install.log
  • Reboot your system.
  • Stop Kolab services and run the configuration utility:
sudo /kolab/bin/openpkg rc all stop
sudo /kolab/sbin/kolab_bootstrap -b
Obviously, you should know all your details, such as your fully qualified host name (which you can determine from hostname -f), domain details, etc., before doing this step. If you are not familiar with OpenLDAPand LDAP basics, you should learn about it, as Kolab uses the slapd OpenLDAP server daemon.
  • Restart all Kolab services:
sudo /kolab/bin/openpkg rc all start
  • Login to the web administrator interface using "manager" and the password you set at bootstrap configuration:
https://yourhost.yourdomain.name/admin

Citadel

Citadel is a turn-key fully open source groupware solution (that is both KDE and Kolab-1 compliant). Based on a bulletin-board framework spanning over 20 years, it is user friendly and interfaces with both KDE and Gnome apps and also has a web-based client. It is also WebDAV compliant and can be used with Thunderbird.

  • Install the Citadel server:
sudo apt-get install citadel-server
  • Install the Citadel client:
sudo apt-get install citadel-client
  • Install both:
sudo apt-get install citadel-suite

eGroupware

eGroupware is a robust and stable free open source groupware solution (with GPL license) based on the LAMP stack (the default server stack included with Ubuntu Server) and the Postfix mail server (both of which should be installed first). There is a new version recently available, with a new corporate sponsor in Germany and a commercial enterprise version. Compatibility with many clients has been improved. Egroupware provides the easiest installation and quickest setup time of all groupware solutions. Much of the documentation for the current version, unfortunately, is not in English.

sudo apt-get install egroupware

Open-Xchange

Open-Xchange is a proprietary groupware solution (meant as an MS-Exchange replacement) that has released a "community edition" based on commercial versions. The latest .deb package is for Hardy Heron 8.04. It is compliant with many different types of clients, including Kontact, Outlook, and Palm PDAs. Installation instructions are at the website and are not trivial.

OpenGroupware

OpenGroupware is a groupware solution based on the postgreSQL database. There is an enterprise version and a limited open source version, and development appears to have been stagnant in 2008. Installation must be from source, as packages are very outdated. See the website for details.

Zarafa

Zarafa is the leading European MS-Exchange replacement/groupware solution. It is proprietary, but a GPL-licensed (except for trademarks) free open-source community edition was released in 2008. Download instructions are available from the website.

Zimbra

Zimbra is a proprietary groupware solution (now owned by VMWare) that offers an open source "community edition". Although currently free, the community edition is limited in features and does not have a GPL license. All submitted modifications and contributions become the property of VMWare. See the Zimbra wiki.

A Beta version for Lucid Lynx 10.04 LTS is available for 64-bit users, or the older Hardy 8.04 version can be used.

SchoolTool

SchoolTool is a free open source groupware solution for use in primary and secondary schools which includes calendaring, gradebooks, attendance records, and student information databases. It was created with the help of the Shuttleworth Foundation (which also sponsors Ubuntu). See these installation instructions.

SugarCRM Community Edition

SugarCRM is a customer-relationship management system that is used to co-ordinate a sales force (sales, marketing, support, project management, calendaring). SugarCRM has a community edition that is one of the most widely used. A LAMP server stack should be installed first ( sudo tasksel install lamp-server ). Extract SugarCRM to /var/www and then logon to http://localhost/SUGAR-FOLDER. Alternatively, for a new server SugarCRM provides a (binary) integrated installation of the LAMP stack with the SugarCRM Community Edition.

Groupware Clients

Many groupware solutions have connectors to interface with clients such as Kontact/KMail and Mozilla Thunderbird (or SeaMonkey).

Evolution Exchange

The Evolution Exchange connector adds connectivity (using Outlook Web Access) to the Evolution suite for MS Exchange 2000 and 2003. Install:

sudo apt-get install evolution-exchange

Kontact Personal Information Manager

The Kontact Personal Information Manager, included in Kubuntu by default, interfaces with many groupware servers.

KDE Groupware Wizard

Kubuntu provides a wizard (script) to help clients (such as Kontact/Kmail) connect to a groupware server. Currently supported groupware servers are Kolab, eGroupware, SUSE Linux Openexchange, and Novell Groupwise.

Zimbra Desktop

Zimbra Desktop is a desktop that collaborates with Zimbra servers. See the Zimbra Desktop FAQ. For more info also see this Ubuntu Forums Zimbra Desktop Installation thread.
