Project Description

The primary target of the Horde/Kolab project is the the integration of the Horde Groupware with the Kolab Groupware Server.



Horde has had partial Kolab support for a long time but the implementation was rather unstable. With Horde-3.2 a lot of the structural problems have been removed as large portions of the code have been rewritten. Currently the project is busy with completing the less central parts of the implementation.


Horde-3.2 will feature stable Kolab Server support for the first time. Only some minor functions in the groupware area do not yet work together with the Kolab Server and some Kolab specific patches have not yet been integrated into Horde CVS.
