Calendars and IMAP

Korganiser suggests: "Calendar on IMAP Server via KMail... Most IMAP servers can be used to hold calendar and address book resources, allowing you to use access your data from just anywhere! " Has anyone tried this recently? If so, how does it work? I have tried all the obvious things, and looked at kolab, which is way more powerful than what I want to do. All I need is a calendar that can be synced to the korganiser calendar. Suggestions? cheers anthony -- Sent from my linux system running Debian 7, desktop trinity-KDE.
