As of version 0.5.6 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.
If you installed WebDAV Client before, you should remove your DAV servers
from zimbraProxyAllowedDomains:
zmprov gc default zimbraProxyAllowedDomains
zmprov mc default -zimbraProxyAllowedDomains allowme.example.com
Make sure to download the latest installer!
wget 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
/tmp/webdav-client-installer.sh
This change has been made to separate the WebDAV Client configuration from the Zimbra Proxy Servlet.
In older versions one could use proxy servlet to access DAV files (if you have enough credentials):
https://zimbra.example.com/service/proxy?target=https://myzimbra.com/owncloud/remote.php/webdav/folder/file.zip
Now you can opt not to allow this servlet, and this can increase security
in scenarios where your DAV server is only accessible in a LAN or vlan.
