Contacts / CardDAV
|
|
==================
|
|
|
|
Nextcloud ships a CardDAV backend for users to store and share their address books and contacts.

System Address Book
|
|
-------------------
|
|
|
|
.. versionchanged:: 27
|
|
The system address book is now accessible to all Nextcloud users
|
|
|
|
Nextcloud maintains a read-only address book containing contact information of all users of the instance.
|
|
|
|
Disabled users are removed from this address book.
|
|
|
|
Privacy and User Property Scopes
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Contact information in the system address book is taken from users' :ref:`profile information<profile>`. Profile properties are only written to the system contact if the :ref:`scope<profile-property-scopes>` is set to *Local* or higher.
|
|
|
|
Users who set all their property scopes to *Private* are removed from the system address book and therefore not seen by other users.
|
|
|
|
:ref:`File sharing settings<file-sharing-configuration>` controls the enumeration of other users.
|
|
|
|
* If username autocompletion is not allowed, the system address book will only show user's own system contact but no other contacts.
|
|
* If username autocompletion is allowed, users will see contact cards for all other users.
|
|
|
|
* If autocompletion is limited to users within the same groups, users will see contact cards for other users in shared groups.
|
|
* If autocompletion is limited to matching phone numbers, the system address book will only show user's own system contact but no other contacts.
|
|
* If autocompletion is limited to users within the same groups **and** matching phone numbers, users will see contact cards for other users in shared groups.

Address Book Sync
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
The address book is updated automatically with every added, modified, disabled or removed user. Admins can also trigger a full rewrite of the address book :ref:`with occ<occ-dav-sync-system-address-book>`.
