========================================================================

Install prerequisites

  • A running Zimbra server
  • A running WebDAV server (for example ownCloud/Nextcloud)

Downloading the automated installer

wget --no-cache https://raw.githubusercontent.com/Zimbra-Community/owncloud-zimlet/soapServiceBarry/webdav-client-installer.sh -O /tmp/webdav-client-installer.sh
chmod +rx /tmp/webdav-client-installer.sh

Multi server support

The zimlet and extensions support multi server ZCS cluster setups where proxies and mailboxes are in different machines. The zimlet and extensions should only be installed on the mailbox servers. The zimlet and extensions must be installed on all of your mailbox servers (refer to the Installing section).

Installing

Use the automated installer (Interactive mode):

/tmp/webdav-client-installer.sh 
[zimbra@server zimbra]$ zmmailboxdctl restart

Use the automated installer (Non interactive mode):

/tmp/webdav-client-installer.sh --auto
[zimbra@server zimbra]$ zmmailboxdctl restart

Non interactive mode does not enable experimental Libreoffice document preview, automatically installs the Zimlet (in production mode) and force enables it in all COS'es. It also installs public link sharing.

Only Office online document editing

Using Zimbra WebDAV Client you can preview and edit docx,xlsx and pptx directly from the Zimbra UI using the power of OnlyOffice by configuring your OnlyOffice Document Server API url in owncloudzimletonlyofficeapiurl. See owncloudzimletenable_onlyoffice below.

In order to make sure OnlyOffice integration works, specially in muti server ZCS clusters, make sure that all of your domains have defined:

  • zimbraPublicServiceHostname
  • zimbraPublicServiceProtocol
  • zimbraPublicServicePort

values which can be found at:

  • Configure
  • Domains
  • example.com
  • General Information
    • Public service hostname: mail.example.com
    • Public service protocol: https
    • Public service port: 443

Document preview

Zimbra WebDAV Client uses OnlyOffice, LibreOffice and jsPDF to display previews of your documents. To enable LibreOffice preview, re-run the installer and choose Y when asked to install LibreOffice Document Preview. Previews are supported for the following file types: pdf,jpg,jpeg,png,txt,md (markdown rendering). Video playback results may be poor supported types: mp4 and webm. If you enabled the optional LibreOffice conversion in the installer, these file types are previewed as well: docx,doc,xlsx,xls,pptx,ppt,odt,ods,odp. On CentOS 7 only (see extras folder): djvu. On top of that the Zimbra WebDAV Client supports editing and redering plain/text and markdown documents.

Configure bruteforce protection

Zimbra WebDAV Client sends all requests to Nextcloud with an X-Forwarded-For HTTP header. You must configure Zimbra and Nextcloud properly to avoid problems with Nextcloud's bruteforce protection mechanism.

On Zimbra:

#Check current config
zmlocalconfig zimbra_http_originating_ip_header
zimbra_http_originating_ip_header = X-Forwarded-For
zmprov gcf zimbraMailTrustedIP #default empty

#Add Zimbra Proxies and Zimbra Server
zmprov mcf +zimbraMailTrustedIP 

#This needs to be told to Zimbra WebDAV Client as well (workaround for an issue in upload handler)
echo -n "zimbramailtrustedips=" >> /opt/zimbra/lib/ext/ownCloud/trustedIPs.properties
echo $(su zimbra -c "/opt/zimbra/bin/zmprov gcf zimbraMailTrustedIP | cut -c22- | tr '\n' ';'") >> /opt/zimbra/lib/ext/ownCloud/trustedIPs.properties

Then in Nextcloud config.php:

'trusted_proxies' => array(''),
'forwarded_for_headers' => array('HTTP_X_FORWARDED_FOR'),

You do not need to restart anything after changing these IP.

Configuring preferences

see github.

Restrict allowed DAV Servers

Your clients can connect to all dav servers by default, you can restrict the allowed DAV servers to connect to in:

/opt/zimbra/lib/ext/ownCloud/config.properties
allowdomains=allowme.example.com;allowmealso.example.com

No service restart is needed after changing this file.

Un-installing (For both production and development mode)

rm -Rf /opt/zimbra/zimlets-deployed/_dev/tk_barrydegraaff_owncloud_zimlet/
rm -Rf /opt/zimbra/zimlets-deployed/_dev/tk_barrydegraaff_docconvert/
rm -Rf /opt/zimbra/lib/ext/ownCloud/
rm -Rf /opt/zimbra/lib/ext/OCS
rm -Rf /opt/zimbra/lib/ext/DocConvert/
zmzimletctl undeploy tk_barrydegraaff_owncloud_zimlet
# It's ok if zmzimlet uninstall fails in development mode
[zimbra@server zimbra]$ zmmailboxdctl restart

Translations

The Zimbra WebDAV Client uses built-in language strings from Zimbra, as such it is translated for all languages that are supported by Zimbra.

Known issues and troubleshooting:

  1. Passwords with characters like @ will not work, try to install this using a simple account and password (A-Za-z0-9). fixed in 0.6.2.
  2. Error 500 but some features work, if you use ownCloud external storage, make sure it is available and marked green.
  3. Running a WebDAV server behind and NGINX reverse proxy (from CentOS or Debian) won't work, it will work when proper options are enabled (as for example with zimbra-proxy, also based on NGINX).
  4. Delay of 30 seconds in response from Nextcloud, the brute force login protection has kicked in. Configure X-Forwarded-For see above! Or and this is not recommended: set in your Nextcloud the preference 'auth.bruteforce.protection.enabled' => false, and issue truncate table bruteforce_attempts;
