Description:
Scalable groupware server
SOGo is a groupware server built around OpenGroupware.org (OGo) and the SOPE application server with focus on scalability. It has many feature enhancements: . * CalDAV and GroupDAV compliance * full handling of vCard as well as vCalendar/iCalendar formats * support for folder sharing and ACLs . The Web interface has been rewritten in an AJAX fashion to provide a faster UI for the users, consistency in look and feel with the Mozilla applications, and to reduce the load of the transactions on the server. . This package contains the SOGo daemon.
