Overview


This talk is about


Exploring Open Source groupware options


Deriving a fare comparison between Open Source options and
Microsoft Exchange



This talk is NOT about

At the end, one must evaluate options that suite their
respective setup.

Shared calendars with free / busy view


Task lists


Meeting / task requests


Address book


Shared folders


File Sharing (Document management)


Single client interface for all services

Groupware Components

Why find an alternative?

Why not?

Why find an alternative?


Licensing cost


Performance and security issues


Integration problems


Standards compliance helps


Full control of your own infrastructure

Options?


Assemble a solution from scratch


Use an already assembled product


Mix and match

Common Pieces


OpenLDAP (Auth and addressbook)



Courier IMAP / POP3 server (Maildir, shared folders)



Postfix / Exim / Qmail (SMTP)



Squirrelmail / Horde (Web based interface)



MySQL / PostgreSQL (Data store)



Calendar (Write your own / use a readymade option)



Outlook Integration (is a problem)

Open Source Groupware options


OpenXchange


OpenGroupware


KOLAB


PHPGroupware (No 1.0 yet)


PHProjekt

Demonstration

Lets take a look at some of the options

Conclusion


There is no completely free, “drop
-
in”
replacement for MS Exchange


It is easier to start from scratch


Most of the cost is either the resources or
the outlook compatibility plugin
