When I’m trying to setup carddav account on Owncloud I get error:
"Missing capabilities, couldn't determine address book home set"
Similar error I got for calendars.
I found problem connected with the @ symbol in login, when I created account “test” everything was working, but it doesn’t seems to be working with account “test@”.
Maybe it is because owncloud suggets me using address https://our.owncloud.address/remote.php/carddav/addressbooks/test%40/contacts (note %40 instead of @)
It would be great if davdroid would be able to support @'s - in our system user logins and user mails are one thing and I believe that it isn’t a strange case.
