[Owncloud] What's the correct URL: for accessing an addressbook from Thunderbird/SOGO connector?

[Chris Green]

I am trying to get Thunderbird to access my owncloud addressbook with
the SOGO connector.

There seem to be lots of different possible URLs to use to do this and I
can't find a definite correct one.  Unfortunately thunderbird doesn't
show any errors when it doesn't work, just silence.

I'm running owncloud version 4.5.7

I'm currently using:-

    http://localhost/owncloud/remote.php/carddav/addressbooks/chris/

but this doesn't work.

There are no errors in the apache2 error.log and just a 'PROPFIND' entry
in the access.log.

I've turned debug on in owncloud, where does the debug output go?
