= Using CalDAV and CardDAV with Open-Xchange =
+
This article is valid until the version 7.10.2 of the Open Xchange Server. For newer versions please visit https://documentation.open-xchange.com/latest/middleware/miscellaneous/caldav_carddav.html
  
Beginning with the 6.20.1 release, Open-Xchange provides interfaces to connect CalDAV- and CardDAV-clients. Please note that at first only MacOS X with its clients "iCal" and "Address Book" is supported. This will change later and support for other clients such as Thunderbird will be added.
+
<!-- = Installation and Configuration of the CalDAV- and CardDAV-bundles =
  
== Preparation ==
+
The Open-Xchange server can be accessed via it's CalDAV- and CardDAV-interfaces to allow the synchronization of Calendar- and Contact-data with external applications like the Mac OS Calendar and Address Book clients.
  
Please edit your file /etc/apache2/ox6.conf so that the existing configuration for ox as well as the new configuration for CalDAV and CardDav is placed inside a virtual host.
+
CalDAV and CardDAV are standard protocols for the exchange of calendar data and address data respectively. The CalDAV interface publishes all the user's calendar folders via CalDAV so the user can subscribe to them in a client application. Similarly, the CardDAV interface publishes the user's contact folders. Depending on the used client, the user can either subscribe one or more folders, or access all available data in an aggregated way.  
  
This is an example where MYSERVER.TLD is the domain-name of the ox-server:

== User Guide and Client Configuration ==
 +
Please find further information regarding the client configuration at [[CalDAVClients]] and [[CardDAVClients]].
  
  $ vi /etc/apache2/ox6.conf
+
== Webserver Configuration ==
 +
In order to redirect DAV requests to the appropiate servlets, the webserver's configuration may need to be adjusted using one of the following alternatives. Please be aware that for a working Mavericks auto configuration setup you need to have SSL enabled on the server. The non-SSL variant described below only works if you use the advanced CalDAV configuration in Mac OS X Mavericks and enter the path by hand. If you just want to enter the hostname, SSL is required. The same applies to iOS7 where SSL is always required.
  
  NameVirtualHost *:80
+
=== Alternative 1: Apache vhost (recommended) ===
  <VirtualHost *:80>
+
Please edit your site configuration file for OX so that ''' the existing OX configuration as well as the CalDAV/CardDAV configuration are placed inside their own virtual hosts sections.'''.

</VirtualHost>
  
== Configuration ==
+
If you use this method, you have to make sure that <code>dav.<MYSERVER.TLD></code> is reachable, your DNS configuration needs an entry for this name. Take care of the the dav.* logfiles, the example writes them without logrotation to <code>/tmp</code>.
  
=== Mac OSX Address Book ===
+
Please note the <code>NameVirtualHost</code> directive is needed to be able to specify multiple virtual hosts for the same IP. The differentiation is only done by the given <code>ServerName</code>. This implies that you need two server names, so the virtual host entry for the existing ox site configuration needs to be also enriched by a <code>ServerName</code> if not already present. If you access the system without one of the given <code>ServerName</code>s so e.g. via the IP the system will pick the corresponding one by order (in this case the DAV part first. If you want it to work differently please change the order accordingly.
  
- Click on the "+" in Address Book -> Preferences -> Accounts.
+
=== Alternative 2: Apache useragent detection ===
- Keep "CardDAV" selected in "Account type"
+
For environments where it is inconvenient to setup a vhost there is the possibility to redirect to relevant servlets another way: Via useragent detection. This is not recommended for the following reason: Per definition this is a whitelist-approach and any client sending a useragent-string not explicitly listed in the configuration will not be able to connect . Useragent-strings may also change between different versions of an application or may even be actively changed into something non-standard.
- Enter your username replacing the "@" with a "*" (e.g. "peter.fraser*MYSERVER.TLD" if you normally log into ox with username ""peter.fraser@MYSERVER.TLD"") as "User name"
 
- Enter your password in "Password"
 
- Enter as the path to the ox-server as follows in in "Server address": dav.MYSERVER.TLD:80
 
- Click "Create"

  RewriteRule (.*)                  http://localhost:8009/servlet/dav$1    [P] # for grizzly http service
 +
 
 +
'''Note:''' The address book app on OSX 10.6 uses a localized user-agent string. If you're expecting clients with non-english language settings, you need to add the translated user-agent string to these rewrite rules. For example: "Adressbuch" for german OSX clients.
 +
 
 +
'''Note:''' Depending on the specific configuration, such a global definition of the rewrite rules might not be appropriate. However, the rules may also be defined inside a <code>Directory</code> context. More details are available at http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule.
 +
 
 +
== Autodiscovery ==
 +
 
 +
By providing some DNS service name registrations for your domain and adding an additional rewrite-rule to the webserver's configuration, it's possible for some clients to automatically discover the account settings by just providing the user's e-mail address and password. The procedure is specified in [http://tools.ietf.org/html/rfc6764 RFC 6764].
 +
 
 +
The following example illustrates the DNS entries where MYSERVER.TLD would be the domain name of the ox-server, both for CalDAV and CardDAV via HTTP and HTTPS on the virtual host dav.MYSERVER.TLD:
 +
 
 +
_caldavs._tcp.MYSERVER.TLD.      10800 IN SRV      10 1 443 dav.MYSERVER.TLD.
 +
_caldav._tcp.MYSERVER.TLD.      10800 IN SRV      10 1  80 dav.MYSERVER.TLD.
 +
_carddavs._tcp.MYSERVER.TLD.    10800 IN SRV      10 1 443 dav.MYSERVER.TLD.
 +
_carddav._tcp.MYSERVER.TLD.      10800 IN SRV      10 1  80 dav.MYSERVER.TLD.
 +
 
 +
Additionally, a rewrite-rule similar to the following example should be added to the webserver configuration of the virtual host to enable the bootstrapping process. The rewrite target must be the root of your DAV server.
 +
The well-known aliases should be added for your DAV vhost and on the vhost serving the host matching the mail domain:
 +
 
 +
RewriteEngine On
 +
RewriteCond %{REQUEST_URI} ^/\.well-known/caldav  [OR]
 +
RewriteCond %{REQUEST_URI} ^/\.well-known/carddav
 +
RewriteRule (.*) / [L,R]
 +
 
 +
In the case of not serving the DAV service on the vhost root additionally some DNS TXT records are recommended:
 +
 
 +
_caldavs._tcp.MYSERVER.TLD.      10800 IN TXT  path=/servlet/dav
 +
_caldav._tcp.MYSERVER.TLD.      10800 IN TXT  path=/servlet/dav
 +
_carddavs._tcp.MYSERVER.TLD.    10800 IN TXT  path=/servlet/dav
 +
_carddav._tcp.MYSERVER.TLD.      10800 IN TXT  path=/servlet/dav

== CalDAV Configuration ==
 +
 
 +
The following configuration options are available in the configuration files <code>caldav.properties</code> and <code>caldav.yml</code>:
 +
 
 +
===com.openexchange.caldav.enabled===
 +
The property '''com.openexchange.caldav.enabled''' governs whether a user has access to the CalDAV interface. This can be configured along the config cascade, in the default setting, everyone that has access to the infostore also has access to caldav. This is achieved in the following way:
 +
 
 +
/opt/open-xchange/etc/caldav.properties:
 +
  com.openexchange.caldav.enabled=false
 +
 
 +
/opt/open-xchange/etc/contextSets/caldav.yml
 +
  premium:
 +
      com.openexchange.caldav.enabled: true
 +
      withTags: ucInfostore
 +
 
 +
 
 +
This means: In general CalDAV is turned off, but using the <code>contextSets</code> feature of the config cascade it is turned on for everyone that has infostore access.
 +
 
 +
===com.openexchange.caldav.tree===
 +
Configures the ID of the folder tree used by the CalDAV interface. Currently, this should be set to the default value of '0'.
 +
 
 +
===com.openexchange.caldav.interval.start===
 +
Defines the minimum end time of appointments to be synchronized via the CalDAV interface, relative to the current date. Possible values are "one_month" (default), "one_year" and "six_months". 
 +
 
 +
===com.openexchange.caldav.interval.end===
 +
Defines the maximum start time of appointments to be synchronized via the CalDAV interface, relative to the current date. Possible values are "one_year" (default) and "two_years". 
 +
 
 +
===com.openexchange.caldav.url===
 +
Tells users where to find a caldav folder. This can be displayed in frontends. You can use the variables [hostname] and [folderId]. If you chose to deploy caldav as a virtual host (say 'dav.open-xchange.com') use https://dav.open-xchange.com/caldav/[folderId] as the value. If you are using user-agent sniffing use https://[hostname]/caldav/[folderId].
 +
 
 +
 
 +
== CardDAV Configuration ==
 +
 
 +
The following configuration options are available in the configuration files carddav.properties and carddav.yml:
 +
 
 +
===com.openexchange.carddav.enabled===
 +
Similarly to CalDAV, the property '''com.openexchange.carddav.enabled''' governs whether CardDAV is available for a certain user. This is configured exactly like CalDAV with the config cascade only enabling this for users that have access to the infostore:
 +
 
 +
/opt/open-xchange/etc/carddav.properties:
 +
  com.openexchange.carddav.enabled=false
 +
 
 +
/opt/open-xchange/etc/contextSets/carddav.yml
 +
  premium:
 +
      com.openexchange.carddav.enabled: true
 +
      withTags: ucInfostore
 +
 
 +
===com.openexchange.carddav.ignoreFolders===
 +
A comma-separated list of folder IDs to exclude from the synchronization. Use this to disable syncing of very large folders (e.g. the global address list in large contexts, which always has ID 6). By default, no folders are excluded.
 +
 
 +
===com.openexchange.carddav.tree===
 +
Configures the ID of the folder tree used by the CardDAV interface. Currently, this should be set to the default value of '0'.
 +
 
 +
===com.openexchange.carddav.exposedCollections===
 +
Controls which collections are exposed via the CardDAV interface. Possible values are '0', '1' and '2'. A value of '1' makes each visible folder available as a resource collection, while '2' only exposes an aggregated collection containing  all contact resources from all visible folders. The default value '0' exposes either an aggregated collection or individual collections for each folder, depending on the client's user-agent that is matched against the pattern in 'userAgentForAggregatedCollection'.
 +
 
 +
===com.openexchange.carddav.userAgentForAggregatedCollection===
 +
Regular expression to match against the client's user-agent to decide whether the aggregated collection is exposed or not. The default pattern matches all known varieties of the Mac OS Addressbook client, that doesn't support multiple collections. Only used if 'exposedCollections' is set to '0'. The pattern is used case insensitive.
 +
 
 +
===com.openexchange.carddav.reducedAggregatedCollection===
 +
Specifies if all visible folders are used to create the aggregated collection, or if a reduced set of folders only containing the global addressbook and the personal contacts folders should be used. This setting only influences the aggregated collection that is used for clients that don't support multiple collections. Possible values are 'true' and 'false. -->
