This module for Dolibarr 3.7/3.8/3.9 add CardDAV / CalDAV and ICS synchronisation. It uses included Sabre/DAV library.

You can :

• Read and Edit calendars through CalDAV
• Read and Edit addressBooks through CardDAV
• Read calendars through ICS Full version or only Free/Busy (hide details)
• Access Dolibarr documents through WebDAV (if admin)

Each user can access his/her contacts address book (public and own private contacts), his/her own calendar and other users calendars according to his/her rights.

Dolibarr contact informations fill personnal informations in client software cards.

Society informations (to which contact is attached) fill professional informations in client software cards.

Cards updated in client software fill only Dolibarr contacts (not Society).

Calendar records with "Status / Percentage" set to "Not applicable" are converted to events in CalDAV (VEVENT), others are converted to tasks (VTODO).

If you find the module is useful and want to finance improvements, consider to pay it on Dolistore

Like all Dolibarr modules, git clone this repository and install cdav directory in dolibarr/htdocs/

Enable CDav module in Interfaces Modules list.

It would add a link in Agenda left menu and in Contacts left menu to access DAV / ICS URLs.

Use these URLs in your CardDAV or CalDAV client software.

• Disable CDav module in Interfaces Modules list.
• Unzip last version or git pull in dolibarr/htdocs/cdav
• Enable CDav module in Interfaces Modules list.

Thunderbird (with Lightning and SoGo Connector addons) needs a precise URL for each address book and calendar :

https://server.example.com/dolibarr/htdocs/cdav/server.php/calendars/<connected-user-login>/<calendar-user-id>-cal-<calendar-user-login>

https://server.example.com/dolibarr/htdocs/cdav/server.php/addressbooks/<connected-user-login>/default/

DAVDroid can detect automatically address book and all existing calendars (if an event exists) with generic DAV URL :

https://server.example.com/dolibarr/htdocs/cdav/

You can use a tasks application to manage Dolibarr tasks (VTODO) on Android. DAVDroid is compatible with OpenTasks.

Be carefull, if you use https, DAVDroid needs a valid SSL certificate, excluding auto-signed certificates.

iOS uses principals url to grab list of CalDAV or CardDAV resources :

https://server.example.com/dolibarr/htdocs/cdav/server.php/principals/<connected-user-login>

Admin users can also access Dolibarr documents through WebDAV with WebDAV URL :

https://server.example.com/dolibarr/htdocs/cdav/server.php/documents/

To test cdav module, you can use DAVDroid url https://server.example.com/dolibarr/htdocs/cdav/ in a web browser. Error messages are clearer.

Apache rewrite module is necessary if you use fcgi or php-fpm mode. In this case, .htacess file in cdav module has to be read by Apache or reported in your Apache configuration.

<IfModule mod_fastcgi.c>
	<IfModule mod_rewrite.c>
		RewriteEngine on
		RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
	</IfModule>
</IfModule>

It is recommanded to disable these Apache modules : dav / dav_fs / dav_lock

fastcgi_param PHP_AUTH_PW $http_authorization;

or

fastcgi_pass_header Authorization;
