Johan,

As far as I can tell the NTLM authentication was in fact successful. No
problem there. The request was rejected because the target server
expected the SEARCH request to provide some content and a content-length
header, which was missing in the request. 

This appears to be a problem caused by the Slide library you are using.
As far as I know stable releases of Slide are incompatible with
HttpClient 3.0. Anyways, you should seek assistance at the Slide user
list.
