Fetching a folder with the unique ID

[Ada]

I'm new to Open-Xchange and wan't to use the WebDAV interface. As described in the Wiki under OXWebDAV#Fetching_Folders

It is possible to request all folders for a specific user or even a only one folder if the unique ID ("object_id") is known.

, but when I send a request, for example:

PROPFIND /servlet/webdav.folders HTTP/1.1
Content-Type: text/xml
User-Agent: user agent
Host: myhost_x
Content-Length: 168

<D:propfind xmlns:D="DAV:" xmlns:ox="http://www.open-xchange.org">
<D:prop>
<ox:object_id>28055</ox:object_id>
</D:prop>
</D:propfind>

I always get ALL the folders (including the folder with the given object_id)! That's the problem.

Any idea??
