Hi,

I spent a long long time trying to use CardDav Server + SoGo + Thunderbird.
I have 20.000 contacts ++

I manage to make it work a bit with :

Sogo Connector installed
Lightning extension installed
URL : http://xx.xx.xx.xx:port/addressbooks/users/MYUSER/addressbook/

I upload a VCF file into the Syno CardDav server to upload all my contact.

Then I created an empty contact list, but have to use the external IP adress instead of a DNS name, I do not know why, but seems he can not sync with a DNS name, even if he asked the password. Idem if I try to use HTTPs, with the DNS name it do nothing except asking the password (My certificate is valid) or If I use the IP, and accept the fact that the certificate is not valid for the IP, it does not sync.

This is the first problem, I can not use HTTPs, and/or DNS Name.

With HTTP & IP address, it is working for downloading, editing or deleting contact.
BUT, it does not work for creating contact.
I have A 403 Error like this :

Avertissement : « nsIOService::NewChannelFromURI() » est obsolète, veuillez utiliser « nsIOService::NewChannelFromURI2() » sogoWebDAV.js:174:22

I saw in a request, that the VCARD sent seems not having parameters N & FN.
Maybe this is the problem.
