Enable WebDAV

Once WebDAV is enabled, you can access the OpenKM repository with this URL:


Go to Administration > Configuration parameters:

Field / PropertyTypeDescription



Enable WebDAV service. By default  it is disabled.




Character ":" may cause problems with some WebDAV clients, Enabling this parameter will replace in the URL the character ":" by "_". By default is disabled.

It's recommended enabling this parameter to prevent compatibility problems with some WebDAV clients.

A path like /okm:root/myfile.txt will be translated to /okm_root/myfile.txt


OpenKM WebDAV is based on excellent Open Source Milton WebDAV API for Java. The Milton project maintains a detailed WebDAV client compatibility list that describes a "Recipe for broad client compatibility."


From Linux you can use:

For example, in Ubuntu or any Debian based Linux distro you can install this utility this way:

$ sudo aptitude install davfs2

Make a mount point:

$ sudo mkdir ~/okmdav

And mount it:

$ sudo mount.davfs "http://your-domain.com:8080/OpenKM/webdav" ~/okmdav

To ease the process, add this entry to your /etc/fstab:

http://your-domain.com:8080/OpenKM/webdav /home/username/webdav davfs noauto,user,rw 0 0

And then in the user's home directory, look for ./davfs2/davfs2.conf. There you'll find a if_match_bug 1 line. Uncomment it.

Install a WebDAV client for Windows.

We don't recommend using the  default Windows WebDAV support because is buggy.

Here you have several options:


Probably this is the best choice if you are under Windows, because of its stability and ease of configuration. WebDrive 10 (Version 10.00, Build 2521) has been roughly tested with OpenKM to enhance compatibility effort. This is the supported configuration to work with OpenKM WebDAV connector:

Windows Web Folders

Perform the following steps in Internet Explorer:

There are some well-known issues. Please consult the following articles in case of any problem

  • Be aware that there are multiple versions of WebDAV Microsoft libraries (and different type of bugs). To avoid some frustration if these steps don't work for you Update Windows XP for Web Folders, more information at  Web Folder Client (MSDAIPP.DLL) Versions and Issues.
  • Windows Vista and Windows 7 both restrict access to WebDAV servers that use Basic HTTP authentication on non-SSL connections. This restriction can be solved by changing a registry key. Read more on. However, SSL connections do bring improved security. This page from Greenbytes is an excellent resource to analyse & fix problems with your Windows WebDAV client.

Windows XP's "My Network Places"

Windows XP supports 'Network Places' in the standard File dialog:

  • Open networking.
  • Connect as network resource.
  • Write url http://your-domain.com:8080/OpenKM/webdav
  • Set user and password.
  • Open the Registry Editor utility (regedit.exe).
  • Go to  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters, look for TypeUseBasicAuth and replace the default value "1" by "2" allowing BasicAuth through NON SSL connections.
  • Map your drive using this address: \\your-domain.com:8080/OpenKM/repository/default/okm_root/

More information at our OpenKM Forum.

Other tools


Install any WebDAV client for Mac, here you have some options:

Mac OS X finder.

  • Select in the Finder "Go" and "Connect to Server...".
  • Fill in the WebDAV URL http://your-domain:8080/OpenKM/webdav
  • Enter a username and password.
  • And the document repository is accessible!


Slow WedDAV performance on Windows

If you have a slow webdav connection in windows 7 please follow the instructions in Fix Slow WebDAV Performance in Windows 7. It turns out to be a windows issue, not OpenKM.

Furthermore in Windows 7/Vista you need to add your certificate (if its not issued by a verified CA) into windows if you plan to use Webdav over SSL (and,like me, do not compensate with digest auth):

  1. Get the certificate from the server administrator in CER format or download it from Firefox.
  2. Start windows Certificate Manager: in command line type certmgr.msc
  3. Select on the left Trusted Root Certification Authorities.
  4. In the menu Actions > All Tasks select Import and then Next.
  5. Browse for the location of certificate file you saved earlier on your computer and click Open.
  6. You will get a few more warning messages. Just say to go through with it until the certificate is accepted.

Then map webdav content as a network drive without any other software. The folder should be: http://your-domain:8080/OpenKM/webdav

To make sure that everything is ok with certificates, open the address using IE. If no warning pops up is shown, then is right.

This allows you only to read/view files. If you need write access over a network drive you need to disable File Locking (windows does not support webdav file lock).

For Windows XP there is a fix (KB907306).

Turn off file locking

If you need to write access over a network drive you need to disable File Locking (windows does not support webdav file lock).

Execute registry editor tool, in command line type regedit. Modify or create this configuration parameter:
