I'm trying to sync one of my friends' calendars in Mac OSX El Capitan. When I try to create a calDAV account and enter the required information, I get "unable to verify account name or password." error message. Here is the info I provide:
Account name: manual
User Name: joe
Server Address: https://example.com/owncloud/remote.php/principals/users/joe
Is the server address correct? Does it work with https? Because there is no http.
