Correct.  Locking is inherent in WebDAV level 2.

Are you sure?

No, this is incorrect.  I'm a developer of OpenGroupware Coils
<http://sourceforge.net/projects/coils/> which is a
WebDAV/GroupDAV/CalDAV server; WebDAV mounting works in Windows XP,
Vista, and 7.  This includes locking - Microsoft Office makes extensive
use of LOCK-NULL resources.

What syntax are you attempting to use when to mount the WebDAV share?

Regardless of the WebDAV server you are using take a look through the
OpenGroupware WebDAV notes
<http://coils.hg.sourceforge.net/hgweb/coils/coils/file/efb7ab7aac83/src/coils/protocol/dav/NOTES.txt> - it has quite a bit of information regarding WebDAV with various platforms and clients.
