5 Compatible CalDav servers ¶
- Owncloud and Nextcloud: Regularly tested.
- Radicale and Baikal: Works. If you get problems with ’Digest’
authentication, switch back to ’Basic’ (make sure to use https,
though!). If you get asked for password repeatedly, put it in
.authinfo file (Storing authentication information).
- SOGo and Kolab: Reported to be working
(https://docs.kolab.org/client-configuration/emacs.html)
- Google Calendar: Should work, but you need to register an
application with the Google Developer Console for OAuth2
authentication (see below), because Google explicitly forbids to put
client id/secrets into open source software (see
https://developers.google.com/terms, section 4b, paragraph 1). Instead
of doing that though, I’d rather suggest you choose another service
provider.
