2006-12+21 khaeru: might this be handled by the ubuntu-server-tasks spec?
é
21/12/2006 - I think we should pick an existing suite, i.e. hula and then create the ubiquitous middleware to achieve what we want

13/07/2007 (stephan-impilinux) - We have recently evaluated a load of
these solutions and have some professional experience in it.

2008-06-07 (pixelpapst) - Just a quick reminder that the hula project
ist effectively dead since late 2006, and the community created a fork
called "bongo project". However, by now they ripped out all of Hula's
LDAP connectivity, which makes this a very pretty but useless solution
for SmallBusinessServer.

2008-06-08  (Guy Van Sanden) Citadel seems a very good choice.  IT offers many features (including a Jabber server) and is completely GPL'ed.
The only caveat is that it does not have LDAP support (yet)

2008-06-19 (Art Cancro) -- yes, definitely go with Citadel.  Ubuntu
packages are already being maintained, and the project would be
delighted to cooperate with the Ubuntu team on integration issues.

2008-06-19 (Todd Hanna) I would also like to give a big +1 to Citadel.
They already have the .debs and there is even a connector to use it as
an "Exchange" replacement if you have clients using Outlook.  I have run
it without issue on Ubuntu server since version 6.06.  It's head and
shoulders above the rest at the moment..  and it is easy to setup,
update, and maintain.

2008-07-08 (Stuart Cianos) - I'll also give major points to Citadel, and
have been a longtime user of it. It is the only open-source groupware
package that is self maintaining and straightforward to configure.

2008-07-09 (Stephan Buys) - Please also dont forget Kolab (Citadel
implements the Kolab v1 format). Kolab has 3 plugins for Outlook,
support Horde Webmail, Thunderbird/Lightning and Kontact.

2008-07-09 (Guy Van Sanden) RE Kolab - Kolab is not a full groupware
AFAIK, it does not have a web interface.  Correct me if I'm wrong.

2008-07-09 (Christian Merlin) Remember also SOGo
(http://sogo.opengroupware.org/) it use LDAP for users and PostgreSQL
for database. So It could be easy to integrate with Ebox (http://ebox-
platform.com/). So Ubuntu can became an'easy and powerfull groupware
server like the commercial one.

2008-07-10 (Stephan Buys) Kolab does have a web interface (for admin and
email) through Horde (www.horde.org). Calendars, Contacts and Tasks can
be shared between Outlook/Kontact/Horde/Thunderbird

2008-07-10 - Personally I prefer bongo, however it is still in its
infancy.  It has a great UI, and is targeted at being simple to install
and use

2008-11-14 - (Guy Van Sanden) Zarafa is becoming an option too.  It was
AGPL'd recently and offers many features including CalDAV in the
upcoming 6.30 release.

2008-11-14 - (Stuart Cianos) Only the server-side components of Zarafa
were opened up... There are still numerous proprietary functions that
are unavailable in the AGPL version. There are plenty of completely open
solutions out there (Horde, Citadel, Kolab, etc.) Personally, I use
Citadel (with Funambol for push e-mail) due to its funtionality,
reliability, speed and flexibility... They also have a fantastic
developer/user community that is supportive and communicative.

2008-11-15 - (Guy Van Sanden)  @Stuart Cianos  Actually most of it seems to be in the AGPL version except for the client license required for Outlook usage.  Which is logical, if you are paying for closed source outlook you should also pay for the connector...
I know about citadel, have been running it for 2 years but it does have some issues and lacks certain features like LDAP integration.

2008-11-16 (Stuart Cianos) @Guy Van Sanden: Citadel will allow you to
authenticate against any service which support the underlying
authentication of the operating system (in this case, PAM). I have used
this to authenticate users against PAM using modules such as pam_ldap;
additionally, it can automatically populate an LDAP directory with
information from its global address book for use with external clients.

I do not see eGroupware, what about it?
