====== CardDAV - Address Book ======
===== Installation =====
  * Install //CardDAV Server// from Package Center
  * Open or port forward port 8443 to your DSM
  * I recommend you to enable HTTPS in the application and redirect HTTP to HTTPS.

===== Client configuration =====
==== Thunderbird on Desktop computers (Windows, Mac, Linux) ====
  - Install //CategoryManager// app in Thunderbird --> Add-ons
  - Download [[https://sogo.nu/download.html#/frontends|SOGo Connector]] and manual install from file. Make sure to pick the correct version for Thunderbird.
  - If the SOGo Connector cannot be installed as an app, download the [[https://sogo.nu/download.html#/frontends|SOGo Connector]] with a right-click on the button, then install it from file in Thunderbird.
  - Open Address Book, then click **File --> New -->Remote Address Book**. Right click on the new address book, disable periodic sync, and enter the following URL to connect, replace "user" with your user name.:
    * Synology DSM: <nowiki>https://your.domain.tld:8443/addressbooks/users/user/addressbook/</nowiki>
    * ownCloud server: <nowiki>https://your.domain.tld/remote.php/dav/addressbooks/users/user/default/</nowiki>
  - If you have an existing remote address book, change the URL to sync existing contacts. Right click the remote address book and select //Synchronize//. If you don't, you must initiate the first sync from your mobile device.
  - Thunderbird will ask for the access credentials to your DAV server, enter them, and select //save to Password Manager//. This way, you will not need to enter the credentials repeatedly for Address Book and Calendar sync.
  - After the first manual sync, change the settings of the Address Book to //Periodic sync//.

==== Contacts on iOS 10 ====
  - Before you modify anything on your mobile device, you should make a backup of your contacts in case they get deleted in the process. Install app //Groups// from Qbix and save all Contacts to a single .vcf file. Email the file to yourself, so will have it available on the device should you need it later.
  - Go to //Settings --> Contacts --> Accounts//. If your inital sync should copy contacts from the server, then disable any existing contact account setups and let the device delete all contacts, then create a new contact server setup. If your initial sync should copy contacts from the device, then you must modify the existing contact server setup.
  - Settings for the server setup are as follows:<code>Server       your.domain.tld
Username     user
Password     *****
Description  your server name
Use SSL      <enable>
Port         8443
Account URL  (filled in automatically)
</code>
