Radicale is a calendar server following the CalDAV protocol. It allows you to synchronize calendar events, contact information and notes across devices and to share these within groups.
The web-interface is used to create, delete calendars It can not be used to manage your calendars. To edit the calendar you will have to setup a client for your device (see setup).
You can find the web interface at https://cal.physik.fu-berlin.de. Logging in is done with the normal ZEDAT-credentials.
A web-interface to edit your calendars is available at https://cal.physik.fu-berlin.de/infcloud. You can log into it with you ZEDAT credentials.
Personal calendars can be shared with groups. To do this enter the name of the group (e.g. ag-franke, ag-vorlesung, feinwerk…) in the field owner when creating the calendar.
After a couple minutes the calendar should be available to all members of the selected group.
On top of this it is possible to give individual users permission to a collection by using the “Individual permissions” field. This option takes a comma separated list of the pattern user:permission. The available permissions are “r” for read access and “w” for write access. If, for example, if user bob is supposed to be able to read and writer the collection and alice should only be able to read it, the option should be set as:
Because radicale is compliant with the CalDAV protocoll every calendar application supporting CalDAV should work with radicale. Below you'll find configurations for different operating systems that we tested and recommend
In general when setting up a client these fields are required
In most applications you can choose which of the availablen calendars you want to sync with your device.
For Linux and Windows we recommend using Thunderbird with the Lightning, TbSync and Provider for CalDAV & CardDAV add-ons.
After installing these add-ons and restarting Thunderbird you can open the calendar settings by clicking Tools → Add-On Preferences → TbSync. To set up the synchronization you click Account actions → Add new Account → CalDAV & CardDAV → Manual Configuration → insert CalDAV-address, username and password → Next → Finish
Now select Enable and synchronize this account, select the calendars you want to sync and click Synchronize now. The calendars should now be available in Thunderbird.
Download the App DAVx5 and simple calendar. In DAVx5 click on the ⊕-button → select to sign in with username and password → insert CalDAV-address, username and password and select to sign in → If necessary approve the certificate → specify a name for the account and accept to create it
The account should now be available in the start menu of DAVx5. Select it and go to the tab CALDAV. Here you can now select which calendars to synchronize onto your device. After selecting tap the synchronize-button (🔁).
Now you can enable this CALDAV-account in your calendar app. For the “simple calendar” app you can enable the account as follows: Open the app → open the menu in the upper right corner → select settings → select CalDAV synchronization → select your account in the list and tap ok
Now the calendar events from the server should be appearing in your calendar. You can now also select between local and synchronized events when creating a new event.
Start the settings app → Password & Accounts → Add Account → other → Add CalDAV Account → enter CalDAV-address, username and password → Next → select Calendars and select Keep on My iPhone on the pop-up !(if you don't do this, your local calendar data might get lost)! → select Reminders (if you want reminders) and again select Keep on My iPhone! → Save Your calendar should now synch with the calendar server. In the calendar app you can tap Calendars to open the calendar selection and select, which remote calendars you want to synchronize. When adding a new event you can select the calendar to decide if the event is to be saved locally on your phone or on the calendar server.
