carldav

A lightweight CalDAV and CardDAV server for personal use powered by Spring Boot.

Supported clients

So far caldav has been tested with the following clients:

• Mozilla Thunderbird with TbSync
• Evolution (on Fedora 23)
• DAVdroid and OpenTasks
• iOS iCalendar (version 4)

Installation

Dependencies

• Java 17

Build and package

• run ./mvnw package or mvnw.cmd on Windows
• you will find a fat jar (Spring Boot application) int the target folder
• run java -jar target/carldav.jar

Configuration

If not specified carldav will create a random admin password on every startup. Generated admin password can be found in the logs: 19:08:41.678 [main] INFO carldav.bootstrap.AdminUserCreator - admin user 'root@localhost:test'

If you want to set your own persistent admin password create config/application.properties file in the same directory as carldav.jar. Add carldav.admin.password with your desired password to application.properties, for example.: carldav.admin.password=4b033fad-db09-4aa3-852b-87aa2b2598ea

Admin user name is set to root@localhost. You can change it with the property carldav.admin.name.

Add a user

In the current state of development caldav doesn't support a web ui. Therefore you'll need to issue a HTTP request by hand in order to create a user. For example:

curl -i --user root@localhost:4b033fad-db09-4aa3-852b-87aa2b2598ea -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d '{"email": "you@localhost", "password": "password"}' http://localhost:1984/carldav/user

Connect your client to carldav

• Mozilla Thunderbird with TbSync: set CalDAV and CardDAV server address to http://localhost:1984/carldav/dav/you@localhost/calendar. Contact sync will be configured automatically.
• Evolution: set CalDAV server address to http://localhost:1984/carldav/dav/you@localhost/calendar and CardDAV server address to http://localhost:1984/carldav/dav/you@localhost/contacts. In addition, you can use VJOURNAL calendar entries (Evolution Memo) as defined in RFC 4791.
• Android: Set CalDAV and CardDAV server address to http://localhost:1984/carldav/dav/you@localhost/calendar. Contact sync will be configured automatically.
• iOS: ehm, you know it.
