FLOSS developers working on closed source solutions replacement are in many aspects similar to magicians. First, they both try to understand and reproduce existing routines. Finally when the secret is revealed, they try to figure out a way to improve or revolutionize it and take it to the next level.
This parallel will be used along the talk to illustrate OpenChange progresses since last SambaXP: MAPI development libraries and OpenChange server status, impact of Exchange documentation on development, etc..
If you want to fight the Borg, you better have a good Warp engine. Similarly, competing with Microsoft Exchange requires OpenChange to develop a robust, reliable and extensible server.
This presentation first provides a quick status update on OpenChange and its MAPI library. It next focuses on OpenChange server design and architecture. The talk finally concludes with a live demonstration of the server running with Microsoft Outlook and what can be expected from OpenChange within next months.
OpenChangeProxy est un serveur proxy hybride Open Source sous license GPL version 3 ou ultérieure capable de comprendre et de parler les protocoles impliqués dans les communications entre Microsoft Exchange Server et Microsoft Outlook. OpenChangeProxy fonctionne avec le serveur Samba4 et propose une gestion de modules avancée permettant le developpement et l'ajout rapide de nouvelles fonctionnalités.
OpenChangeProxy est en mesure de surveiller et analyser passivement les communications Outlook-Exchange et, à titre d'exemple, de repliquer les créations, modifications ou suppressions d'évènements calendrier sur Google calendar.
Il peut également adopter un comportement actif et modifier le contenu du traffic Outlook-Exchange en temps réel. Combinée à d'autres briques logicielles, le développement de modules de securité antivirus MAPI ou antispam Open Source devient possible.
Enfin il offre l'environnement nécessaire à la substitution progressive et transparente d'un serveur Exchange par une autre solution de travail collaboratif et facilite la migration des données.
OpenChangeProxy est déjà disponible dans Debian, Ubuntu Intrepid et devrait faire partie de la distribution de base de Fedora Core 11. En outre, le développement de modules openchangeproxy fait désormais parti du cursus de l'EPITECH et devrait rassembler une communauté de développeurs de l'ordre de 120 étudiants de quatrième année sur une période allant d'Octobre 2008 à Janvier 2009.
OpenChange and KDE - bridging to Microsoft Exchange
21st - 24th January 2009 (Hobart, Australia)
Author: Brad Hards
Abstract:
Once upon a time, in a land called KDE, there lived a bunch of happy hackers. Every so often, they looked over to the neighbouring lands of the Evil Empire, and saw the masses who would come to the free and open lands of KDE, if only the masses could unshackle themselves from the chains of Microsoft Exchange.
Then one day, a couple of hackers from the lands of KDE found a small enclave of hackers in a land called OpenChange. OpenChange was close to the kingdom of Samba, where good king Tridge presided. Amongst the fine works of OpenChange and Samba, there was a big sign saying "Exchange compatibility this way". And the KDE hackers rejoiced, for it was good (if a little rough around the edges).
Come along to:
understand how the introduction of Akonadi in KDE 4.1 enables the easy development of Groupware clients, without having to write all that tricky network code yourself;
find out how OpenChange libraries allow access to Exchange servers using native protocols ("as seen in Outlook");
and see how Akonadi and OpenChange are used together to allow KDE4 groupware clients to access Exchange servers.
The OpenChange MAPI client library 1.0 baptised BORG will soon be released and will provide full-features and complete access to Microsoft Exchange Server from UNIX platforms: email, calendar, contacts, address book, tasks, notes or public folders. This library has been a long time coming but is finally on the right track, feature complete, and intended to be used in production environments. The first part of the presentation will provide an overview of existing libmapi applications - graphical or console based - and focuses on visual demonstrations.
However OpenChange does not only supply client-side MAPI capabilities. The server side is also in progress and aims to provide a transparent Exchange server replacement based upon Samba4. The last part of this demonstration will focus on OpenChange server design, how it uses Samba4 infrastructure and its current development status.
Après avoir introduit le contexte économique du projet, nous présenterons les différentes composantes d'OpenChange à l'aide de démonstrations: fonctionnalités de la bibliothèque de développement de clients MAPI et d'outils d'administration d'un serveur Exchange. Nous détaillerons ensuite la stratégie retenue par OpenChange sur l'année 2008, ses collaborations avec d'autres projets Open Source et son positionnement sur le marché du travail collaboratif.
The OpenChange MAPI library aims to provide an Open Source implementation of Microsoft Exchange protocols under unix/linux. Firstly we provide a general overview of MAPI internals and the OpenChange MAPI library architecture. Then we focus on real-world programming examples and detail the internals of two sample applications based on libmapi, fetching Exchange e-mails and calendar items from a Linux terminal. Finally we provide an overview of graphical and console Linux desktop applications using OpenChange.
This presentation focuses on the relevant advances OpenChange made since the last SambaXP conference. The presentation will include a brief overview of the project integration with Samba4, a live demo of successful communication between Outlook 2003 and the OpenChange implementation of the EMSABP provider. Last but not least, the contributions OpenChange made or is currently working on will be mentioned.
This presentation intends to provide a complete overview of the OpenChange project progress. The first part of this talk offers an overview of the project context, describes its main objectives and discuss the integration with Samba4. The second part presents the different tools developed by the OpenChange team in order to facilitate the Exchange protocols analysis, information gathering and sharing. The last part of this presentation details the progress made since the last SambaXP conference.
