SOGo is a very fast and scalable modern collaboration suite (or groupware). It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins) to many clients such as Microsoft Outlook, Apple iCal, the iPhone, Mozilla Lightning, and a plethora of mobile devices via SyncML. It can reuse any existing email and database infrastructure, avoiding long hours of site restructuring.
Inverse Lightning enhancer plugin enhances the functionalities of the Lightning calendar plugin for Thunderbird. It is meant to add better integration with CalDAV compatible servers such as SOGo. It provides support for CalDAV freebusy information in the scheduling interface and in the addressbook. It manages the iCalendar organizers by taking into account the identities configured in Thunderbird. And it fixes bugs found from time to time in Lightning which are not yet fixed upstream.
Inverse SOGo Connector for Thunderbird is an extension which transforms Thunderbird into a full DAV client for groupware servers such as SOGo, OpenGroupware.org, and Citadel. It does this by adding support for remote DAV address books and by adding features to be used along with the Lightning calendar extension. It is a merge of the Lightning Enhancer and the GroupDAV Addressbook Connector.
Inverse SOGo Integrator for Thunderbird is an extension that transforms Thunderbird into a pure "heavy" client for SOGo. Whereas the SOGo Connector is meant for portability, the SOGo Integrator provides "vertical" integration with the SOGo groupware server by making use of the specific features it provides. The general features provided are: remote administration of folder subscriptions, an automatic replication of user folders and subscriptions, propagation of updates to chosen extensions from a local update server, and propagation of default settings and integrated GUI elements.
