Hi Angela,
I had a look into the jackrabbit webdav api, to understand how things are
done.
So here are the request headers from performing an unlock by netdrive
(that fails):

And here I have the webdav multistatus response:

</D:multistatus>
Having a look into rfc 2513 (
http://www.apps.ietf.org/rfc/rfc2518.html#sec-12.1.2) the response seems
to be ok.
There is just the lock token missing, because I can't see any lock related
headers in the request of NetDrive.
Do you need more information?
