CalDAV Interface

General

CalDAV is a cross-manufactur standard that allows you to synchronize calendars or appointments between different devices or applications. Limbas provides a CalDAV interface that supports the following features of the standard:

• All-day or temporary appointments
• Regular Schedule Repetitions: Set daily, weekly, monthly, or yearly recurring appointments.
• Appointment Reminders: Reminders are displayed a specified amount of time before the appointment starts in the user’s calendar application. Reminders are automatically created in LIMBAS and linked to the appointment.

Setup

To set up CalDAV with different clients, the following LIMBAS data must be known:

• <LIMBAS-URL>: The URL to the base of the LIMBAS installation, e.g. “domain.de/openlimbas”.
• <LIMBAS-USER>: The name of the LIMBAS user, e.g. “admin” (the user of course must have the rights to access the calendar)

Thunderbird also requires the following information:

• <CALENDER-ID>: The ID of the corresponding calendar or calendar table (see also Table Settings).

With CalDAV new appointments are synchronized intermittently or manually between different devices. Depending on the frequency of appointments, the synchronization interval can be set step by step to manual, every minute, every 5 minutes, every hour, etc.

On iOS, the calendar can be set up as follows:

1. Open “Settings” > “Mail,Contacts,Calendar” > “Add Account…” > “Other” > “Add CalDAV-Account”
