What's the correct method presently for accessing multiple address books via CardDav from Apple's Contacts application on Mac?
For example, user 'foo' on my ownCloud 9.1 server has a default address book. The URL for this is 'https://example.com/remote.php/dav/addressbooks/users/foo/contacts/' and I can access this successfully from Contacts 10.0 (1756.9).
I created a second ownCloud address book called 'bar'. The URL for this is 'https://example.com/remote.php/dav/addressbooks/users/foo/bar/'. If I try to add this as a second "account" in Apple's Address Book, it shows, "This account already exists."
Simply having access to the first address book via CardDAV does not cause the second to appear in Address Book. How can I cause it to do so?
