I have a mainly working environment with thunderbird 3.1, sogo connector and apple calendar server, but I cannot create new contacts from thunderbird because of the use of the old carddav draft in sogo (sogo-connector uses x-vcard and not vcard as mimetype and so the server does not accept the information). This compatibility issue should be fixed (bug 933), but I have no information that it is already working or it is time to try it again.
Can you create new contacts from thunderbird via sogo-connector? -- users@sogo.nu https://inverse.ca/sogo/lists
